Match with Top-Tier TalentsSee how it works
In short
Hire App Developers at TechHub gives you senior mobile app developers from Hanoi, Vietnam, shortlisted within 48 hours and productive within about a week. You keep the roadmap and the code; we handle sourcing, employment, payroll and compliance under ISO 9001:2015 and ISO 27001:2013 certified processes.
What it is
What do mobile app developers do, and how do they work with your team?
Mobile developers at TechHub design, build and ship production iOS and Android applications end to end. That means architecture and data modelling, native or cross-platform implementation, API and offline-sync integration, automated testing, store submission and post-launch monitoring. They join your team as senior owners — attending your standups, working in your repo and your definition of done — rather than as ticket-takers who need constant supervision.
The practical difference shows up in the details that decide whether an app succeeds: startup time and frame rate on mid-range Android devices, battery and memory behaviour, graceful offline states, secure token storage, and a release pipeline that lets you ship weekly instead of quarterly. Our engineers have delivered apps that reached 1,000+ downloads in their first month, so these are lessons learned in production rather than theory.
Capabilities
What can our mobile app developers deliver?
Each engagement is staffed against the capabilities your roadmap actually needs.
Native iOS & Android
Swift, SwiftUI, Kotlin and Jetpack Compose for apps that need maximum performance, platform APIs and long-term maintainability.
Cross-platform delivery
React Native and Flutter so one team ships both platforms from a single codebase, typically cutting mobile delivery cost by 30–40%.
API, sync & offline
REST and GraphQL integration, background sync, conflict resolution and encrypted local storage for apps that must work on poor connections.
Performance engineering
Profiling, cold-start reduction, memory and battery optimisation, and crash-free-session monitoring after release.
Release & CI/CD
Automated builds, signing, staged rollouts and App Store / Google Play submission, including review-rejection handling.
Security & privacy
Secure authentication, certificate pinning, data-at-rest encryption and privacy-manifest compliance for both stores.

Which app specialisation do you need?
Hire by the exact technology. Each page covers skills, typical use cases and engagement options for that specialisation.
Use cases
What can you build with mobile app developers?
Clients typically bring us one of a handful of situations, and the right team shape differs for each. The list below reflects what we are asked for most often across 300+ delivered projects.
- Consumer apps that must scale to hundreds of thousands of users
- Enterprise and field-workforce apps with offline requirements
- Marketplace, booking and fintech apps with payment integration
- Modernisation of ageing apps and migration to cross-platform
- MVPs validated in weeks rather than quarters
Which technologies can you cover?
Our 200+ engineers cover more than 100 technologies. If a stack is missing, we recruit for it — most specialised roles are filled within two to three weeks.
Engagement
Which engagement model should you choose?
Most clients start with one model and evolve. The decision usually comes down to two questions: who owns day-to-day management, and how long you need the capacity. We will tell you when a smaller engagement is the right answer.
- Need specific skills fast, keep control → staff augmentation
- Need a managed unit for a long roadmap → dedicated team
- Want a local presence you eventually own → BOT / ODC
Staff augmentation
Individual engineers join your existing team, under your management and inside your process. Best when you know what to build and need specific skills or extra capacity.
Commercial model: Monthly, per engineer
Dedicated team
A complete team — engineers, QA and a delivery lead — works exclusively on your product, managed by TechHub to your standards. Best for sustained roadmaps and several workstreams at once.
Commercial model: Monthly, per team
Build-Operate-Transfer / ODC
We build and run a dedicated centre in Vietnam, then transfer it into your ownership once it is stable. Best when you want a permanent local presence without running market entry yourself.
Commercial model: Phased, by agreement
Process
How do you hire mobile app developers from TechHub?
Four steps, roughly one week from brief to a productive engineer.
- Share the briefTell us the role, seniority, stack and timeline. We turn that into a role profile and success criteria.
- Receive a shortlist in 48 hoursWe screen our vetted pool and send profiles with real project context, not keyword-matched CVs.
- Interview and decideYou run your own technical and cultural assessment. You make the final call.
- Onboard in about a weekContracts, accounts, tooling and security briefing are handled. A free replacement applies during the trial period.
Process
What happens in the first 30 days?
Speed only matters if the engineer becomes productive. This is the ramp plan we run on every engagement.
- Days 1–2 — access and contextAccounts, repositories, environments and security briefing. The engineer reads your architecture notes and meets the people they will work with.
- Days 3–5 — first contributionA small, real ticket goes through your full review and release process, so integration problems surface immediately rather than in week four.
- Week 2 — full sprint participationThe engineer takes normal sprint load, joins ceremonies and starts contributing to estimates and technical discussion.
- Week 3–4 — ownershipThey own a feature area end to end. We hold a 30-day review with you covering delivery, communication and fit — with a free replacement if anything is off.
Quality
How do you vet engineers before we see them?
Roughly three per cent of applicants join the TechHub pool. The screen is deliberately expensive to pass, because the cost of a wrong hire lands on your roadmap rather than ours.
- CV and experience verificationReal project history, references and employment checks — not keyword matching.
- Live technical assessmentWorking code under observation, in the stack the role actually requires.
- System design discussionTrade-off reasoning, not memorised patterns.
- English and communication interviewB2–C1 level so the engineer works with your team, not through a translator.
- Reliability and reference checkDelivery track record, ownership and how they behave when something goes wrong.
How does this compare with hiring locally?
The comparison that matters is total elapsed time and total cost, not the hourly rate in isolation.
| Criteria | In-house hiring | TechHub |
|---|---|---|
| Time to productive engineer | 2–3 months | ~7 days after selection |
| Sourcing & technical screening | Your team’s time | Handled; 3% acceptance rate |
| Payroll, tax & compliance | Your overhead | Fully managed in Vietnam |
| Wrong-hire risk | Costly and slow to unwind | Free replacement during trial |
| Scaling down | Redundancy process | Agreed notice period |
| Intellectual property | Yours | Yours, assigned contractually |
Which industries have you delivered in?
Domain familiarity shortens ramp-up: engineers who have already handled payment reconciliation, clinical data or logistics tracking do not need six weeks to understand your constraints. Across 300+ projects we have worked in:
Commercials
How is pricing structured, and what is included?
Pricing is quoted per engagement rather than published as a single rate, because seniority, stack and duration move the number significantly. What matters commercially is that our quotes are all-in: sourcing, five-step vetting, employment contracts, payroll, personal income tax, statutory insurance, workspace, equipment and delivery management are already included. There is no separate recruitment fee and no hidden employer-cost surprise.
For budgeting, most clients compare our all-in monthly cost against the fully loaded cost of a local hire — salary plus employer contributions, recruitment fees, equipment, workspace, management overhead and the two-to-three-month vacancy before anyone starts. On that basis, senior engineering capacity in Vietnam is consistently the more efficient option, which is why clients keep teams with us for years rather than months.
Contracts run monthly with an agreed notice period, so you can scale down without a redundancy process. You receive a written quote against your specific role profile before committing to anything.
Security & compliance
How do you protect our code, data and IP?
Every engagement runs under an information-security management system aligned to ISO/IEC 27001, with quality processes certified to ISO 9001. In practice that means role-based access to repositories and environments, device and password policy, segregated networks in our Hanoi centre, logged access to production data and a documented offboarding checklist so credentials do not outlive an engagement.
Contractually, intellectual property in everything we build is assigned to your company, NDAs cover every individual on the engagement, and we can sign your own security addendum or data-processing agreement. Clients in fintech, healthcare and insurance have taken our teams through their own vendor security reviews.
If your compliance team needs evidence, we provide certification documentation, policy summaries and named points of contact rather than generic assurances.
Why it works
Why do companies outsource engineering?
Recruiting a senior engineer in the US or Western Europe typically takes two to three months and commits you to fixed cost long after the project that justified it. Outsourcing to a vetted partner converts that into flexible capacity: you add proven engineers in days, scale down without a redundancy process, and keep your own team focused on product and customers.
Outsourcing (Wikipedia) and Offshoring (Wikipedia) are now standard operating models for software companies rather than cost-cutting measures of last resort. The decisive factor is not the hourly rate but whether the partner stays accountable for quality and retention once the contract is signed.
Location
Why Vietnam, and why Hanoi specifically?
Vietnam is one of Asia’s fastest-growing technology economies (World Bank — Vietnam), producing a large annual cohort of STEM graduates with strong engineering fundamentals and improving English. Senior engineering costs run substantially below US and Western European levels for comparable seniority.
Working hours overlap with both APAC business hours and European mornings, so you get real-time collaboration rather than overnight hand-offs. Hanoi in particular concentrates universities, technology parks and a mature IT services sector, which is why our 200+ engineers are based there.
Why us
Why choose TechHub as your engineering partner?
We have spent 10+ years building software and technical teams from Hanoi, delivering 300+ projects for clients in 12 countries with a 90% client satisfaction rate. Every engineer passes a five-step screen with a 3% acceptance rate.
Delivery runs under ISO 9001 and ISO/IEC 27001 certified processes, with NDAs and full intellectual-property assignment as standard. Crucially, we stay accountable after the placement: we manage retention, replace poor fits at our cost during the trial period, and report on delivery rather than disappearing once an engineer starts.
That combination — senior talent, compliant employment and ongoing delivery ownership — is what separates a long-term engineering partner from a CV-forwarding agency.

Outcomes are drawn from verified client engagements; average rating 4.9/5 across independent B2B review platforms.
Our people
Who will actually be working on your product?
Engineers stay with us for years, and that continuity is what protects your institutional knowledge. Our teams run internal workshops, speak at developer events such as Vietnam Mobile Day, and have hosted community meetups in Hanoi — the same people you interview are the ones who ship your product.
FAQ
Frequently asked questions
What does a mobile app developer do at TechHub?
Mobile developers at TechHub design, build and ship production iOS and Android applications end to end. That means architecture and data modelling, native or cross-platform implementation, API and offline-sync integration, automated testing, store submission and post-launch monitoring. They join your team as senior owners — attending your standups, working in your repo and your definition of done
How much does it cost to hire mobile app developers in Vietnam?
Cost depends on seniority, stack and engagement length rather than a single published rate. Senior engineering capacity in Vietnam generally costs substantially less than equivalent US or Western European hires, and our pricing is all-in: sourcing, vetting, employment, payroll, statutory contributions and management are included, so there is no separate recruitment fee. Ask for a written quote against your specific role profile.
How fast can mobile app developers start?
We shortlist pre-vetted candidates within 48 hours of an agreed role profile. After you complete interviews, onboarding typically takes about a week, covering contracts, accounts, tooling and a security briefing. Local hiring for the same seniority usually takes two to three months.
How do you vet mobile app developers?
Every engineer passes a five-step screen: CV and experience verification, a live technical assessment, a system-design discussion, an English and communication interview, and a reliability and reference check. About 3% of applicants are accepted into the pool.
Do I manage the engineers, or does TechHub?
Both models are available. With staff augmentation you manage them directly inside your process. With a dedicated team, a TechHub delivery lead manages day-to-day execution against your priorities and reports on progress. Many clients start with augmentation and move to a managed team as scope grows.
Who owns the code and intellectual property?
You do. Intellectual property is assigned to your company contractually, NDAs are standard, and delivery runs under ISO/IEC 27001 information-security controls covering access management, device policy and code handling.
What happens if an engineer is not the right fit?
A free replacement applies during the trial period. In practice, mismatches are rare because you interview and select every engineer yourself, but the guarantee removes the downside risk of the decision.
Can I scale the team up or down later?
Yes. Engagements are structured so you can add engineers as scope grows or release them with an agreed notice period. This flexibility is the main reason clients choose a dedicated team over permanent local headcount.
