Hire Cross-Platform App Developers for Your Product Team

Stacks and tools we use daily

React Native, Expo, Flutter, .NET MAUI, Firebase, Supabase, GraphQL, REST, Fastlane, Bitrise, Codemagic, AWS Amplify, Azure DevOps, and bespoke Node.js or API backends. We also integrate with your existing tooling — Jira, Linear, GitHub Actions, Firebase App Distribution, TestFlight — rather than imposing our own.

Individual developer

One senior cross-platform engineer embedded in your team. You manage them directly, they follow your processes, they bill monthly. This works best when you already have a product manager, designer, and QA process in place — you just need more mobile hands.

Indicative rate: $4,500–$6,500/month for a senior React Native or Flutter developer. Fully loaded — no hidden management or overhead fees.

Development pod

A self-contained unit: two to four developers, one QA engineer, and optional design or DevOps support. The pod has an internal lead who coordinates with your product owner. You set priorities; we handle execution cadence, code reviews, and release mechanics.

Indicative rate: $15,000–$28,000/month for a three- to five-person pod. Composition and seniority mix affect the final number.

Freelancers

Cheap and fast to engage, but they disappear. No backup, no QA safety net, no accountability beyond the next invoice. For a two-week prototype, freelancers can work. For anything that needs continuity over months, they're a gamble — and you'll spend time managing them that you'd rather spend on product decisions.

In-house hires

Maximum control, but the timeline is a killer. Between sourcing, interviewing, negotiating, and the first 90 days of onboarding, you're looking at four to six months before someone is fully productive. If you hire wrong, you start over with severance costs. Great for long-term roles you're certain about; painful for everything else.

Agencies

They build your product for you. Sounds convenient until you realize the engineering decisions stay with them, velocity depends on their internal priorities, and knowledge lives in their org — not yours. Agencies work for well-defined, time-boxed projects. For ongoing product development, they create dependency.

Staff augmentation (our model)

Sits in the middle: speed and flexibility without giving up control. The developers work on your terms, in your tools, under your engineering standards. When the engagement ends, you keep the code, the docs, and the knowledge. That's the fundamental difference.

Binsensors makes IoT sensors for municipal waste management. When they came to us, they had an Android-only pilot built by a contractor and an iOS proof-of-concept their CTO had prototyped in Swift. Neither codebase was production-ready, and they needed to launch in both stores before their next funding round closed.

We staffed a four-person pod: two senior React Native engineers, a QA automation lead, and a product designer.

• Consolidated both apps into a single React Native codebase with TypeScript in the first month. The hardest part was BLE integration — field sensors use a custom Bluetooth protocol, and React Native's BLE libraries needed native bridges in both Swift and Kotlin to handle edge cases.
• Delivered a design system that adapts to rugged tablets and smartphones, cutting UI maintenance effort by roughly 40%.
• Automated regression testing across iOS and Android, enabling weekly releases instead of the quarterly drops they were doing before.

Month three: both stores approved the app on first submission. Binsensors launched in ten cities that quarter and closed their Series A. Read the full case study.

Communication gaps

Remote developers in different countries can misread priorities or context. We mitigate this by staffing exclusively from Latin America — same time zones, cultural proximity to US teams, and strong English skills. Every developer we place has passed a live communication assessment, not just a grammar test.

Knowledge silos

An augmented developer leaves, and the knowledge goes with them. We require shared documentation, pair programming sessions, and recorded architecture decision records throughout every engagement. If you end the contract, we produce a handover package that your next hire (internal or augmented) can use to get up to speed.

Quality mismatch

The developer interviews well but underperforms on real work. Our two-week trial exists for exactly this reason. We also assign a delivery manager who checks in with both sides during the first month to catch misalignment before it becomes a problem.

Framework lock-in

You pick Flutter, then realize six months later you need native performance for a specific feature. We architect for this from the start — isolating platform channels, keeping business logic separate from UI, and documenting where native fallbacks may be needed. If you decide to go fully native eventually, the transition is incremental rather than a rewrite.

Hiring for the framework, not the problem

A "React Native developer" who has only built CRUD apps won't help you with a real-time IoT dashboard. The framework matters less than domain experience and the ability to debug production issues under pressure. When you talk to us, we push back on framework-first job descriptions and ask about the actual problems your team is solving.

Underestimating native knowledge

Cross-platform doesn't mean "no native." Every non-trivial app eventually hits a native wall — custom permissions, OS-level bugs, performance-critical modules. Developers who can't read Swift or Kotlin will hit a ceiling. We vet for this specifically, even when the job looks 100% React Native or Flutter on paper.

Skipping the trial

You wouldn't hire a full-time employee without a probation period. The same logic applies to augmented developers. Two weeks is enough to see whether someone matches your velocity and communication expectations. We insist on this even when clients say they trust our vetting — because the cost of a bad fit compounds fast.

Release-ready code

Pair programming on critical flows, enforced linting, and CI pipelines that gate merges with automated tests, visual diffs, and security scans. We treat augmented developers like core team — same standards, no exceptions.

Device coverage

Our device lab validates features on flagship and low-end devices, including network throttling and battery drain profiling. We don't ship features that work on a Pixel 8 but crash on a Samsung A14.

Documentation and handover

Runbooks, API references, and recorded demos make transitions smooth — whether for internal hires, investors, or new product managers joining later. Continuity never depends on a single person.
