Hire an Offshore Mobile Team That Ships Like an In-House One
BATSTACK is the custom mobile app development studio US founders and CTOs hire for React Native, Flutter, and native iOS/Android builds — 100% custom code, sub-second APIs, and a transparent Git + Jira workflow. MVPs in 4–6 weeks, with a dedicated daily overlap window across US time zones.
Engineering-first — the offshore team that doesn’t feel offshore
100% custom codebase
Senior-written, tested code you own outright — no templates, no low-code lock-in, no black boxes.
Native-grade performance
Sub-second API responses and 60fps UI as a hard budget, benchmarked, not promised.
In-house-grade transparency
GitHub, Jira, and Slack from sprint one — your team reviews every commit and PR as if we sat down the hall.
Costed scope, no surprises
Fixed sprint plan from Discovery. MVP in 4–6 weeks or a phased enterprise roadmap — predictable spend.
Offshore rates, US standards
Silicon-Valley-grade engineering discipline at a fraction of a US agency’s burn — runway goes into product.
The full engineering stack — mobile to cloud
Cross-Platform Excellence
React Native and Flutter: one maintainable codebase, native feel, faster iteration — ideal for lean startup teams.
Native Mobile
Native iOS (Swift) and Android (Kotlin) when performance and hardware depth demand it.
Resilient Microservices & APIs
Node.js, Go, GraphQL, PostgreSQL — built for scale, real-time sync, and offline-first mobile.
Enterprise Security & Cloud
AWS + Cloudflare, CI/CD, automated testing, SOC-aligned practices, and encryption in transit and at rest.
A transparent 4-phase delivery framework
Discovery
A 30-minute technical discovery call becomes a costed scope — user flows, architecture, tech-stack decisions, and a fixed sprint plan. You leave knowing exactly what, when, and how much.
Interactive Prototype
A clickable, real-data prototype before full engineering begins — so you validate the product and align stakeholders before the expensive part starts.
Agile Sprint Engineering
Weekly sprints, demoed live. Every sprint ships working software to a staging build you can install, with full Git + Jira transparency throughout.
Deployment & SLA Support
Store submission, production launch on AWS/Cloudflare, monitoring, and a defined post-launch SLA for maintenance, updates, and scaling.
What will your build actually take?
Engineering estimates confirmed in Discovery; App Store review time excluded.

Frequently asked questions
Who owns the IP and source code?
You own 100% of the IP and source code. On final payment, all code and design assets transfer to you in writing, and you hold the GitHub repository from day one — critical for your next fundraise or acquisition due diligence.
How does time-zone overlap work across US time zones?
Sri Lanka is UTC+5:30. We commit to a guaranteed daily overlap window aligned to your US working hours for live standups and demos, then run asynchronous progress while you’re offline — so your project advances around the clock.
Do we get repository access during the project?
Yes — GitHub repo, Jira board, and Slack from the first sprint. Full commit- and PR-level visibility, exactly like an in-house team.
What does post-launch maintenance and support include?
A defined SLA covering bug fixes, iOS/Android OS-version updates, security patches, and feature iterations — on a monthly retainer or sprint-by-sprint, whichever suits your stage.
How do you protect our IP and confidential data as an offshore team?
NDA before Discovery, least-privilege repo and cloud access, encryption in transit and at rest, and written IP assignment on delivery. Your GitHub ownership from day one means the codebase is always in your control, never ours.
