Available for senior & lead mobile roles

Naresh Chocha

Senior Mobile Engineer

Senior mobile engineer — native-Android-first by depth (6+ yrs), Flutter-strong by current project mix. I currently tech-lead an 8-engineer cross-platform team and own per-project stack selection, choosing native Android or Flutter based on hardware depth, time-to-market, and long-term maintenance. I own the platform-channel bridge layer that lets both stacks share security, FFmpeg, file-picker, and on-device AI infrastructure.

About

Engineering depth, leadership at scale

I pair hands-on native-Android depth with cross-platform Flutter delivery — and lead the team and own the architecture decisions that turn both into shipped, audited, production software.

GitHub Stars (OSS)

Two stacks, one bridge

Native Android and Flutter sharing a platform-channel layer — security, FFmpeg, file-picker, and on-device AI infrastructure reused across both.

Production on-device AI

Privacy-first TensorFlow Lite & ML Kit pipelines — sub-100 ms inference, quantized models, NNAPI acceleration, zero cloud round-trips.

Security by default

SSL pinning, Android Keystore, encrypted storage, root detection, and R8 hardening — baselines that pass annual third-party audits.

Leadership that scales

Modular architecture, ADRs, code-review governance, and CI/CD that let an 8-engineer team ship in parallel without merge bottlenecks.

Where I've made an impact

6+ years building and leading mobile teams — from individual contributor to tech lead owning architecture, releases, and an 8-engineer team.

Current

Senior Mobile Engineer — Tech Lead, Android & Flutter (8 reports)

Openxcell Technolabs Pvt. Ltd.

Aug 2022 – PresentAhmedabad, India
  • Tech-lead an 8-engineer cross-platform mobile team shipping both native Android and Flutter apps across 5+ concurrent client engagements; own architecture, code-review governance, hiring loop, and technical roadmap.
  • Own per-project stack selection (native Android vs Flutter) based on hardware-integration depth, time-to-market, and long-term maintenance cost — documented as ADRs so the next lead can audit the trade-offs.
  • Architected reusable Platform-Channel bridges exposing native Android capabilities (NFC, geofencing, FFmpeg, FusedLocation, file picker) to Flutter — one Flutter codebase consuming the same native infrastructure across clients.
  • Eliminated cross-squad merge bottlenecks through modular architecture (Modular Monolith for Android; feature-modular Flutter with BLoC + Clean Architecture), enabling parallel feature delivery.
  • Shipped 15+ store production releases across Google Play and Apple App Store with zero critical rollout failures — owned App Store Connect submission, TestFlight, phased rollouts, and Crashlytics-gated promotion.
  • Lead the on-device AI / GenAI evaluation track across both stacks — POCs on Gemini Nano, ML Kit GenAI APIs, MediaPipe LLM Inference, TensorFlow Lite, and LiteRT-LM with a privacy-first hybrid local/cloud routing strategy.

Senior Android Developer

Sky Productivity Pvt. Ltd.

Jul 2021 – Aug 2022Ahmedabad, India
  • Cut the app’s Crashlytics crash rate by ~30% over 2 release cycles through Android Profiler–driven lifecycle audits, memory-leak fixes (LeakCanary), and elimination of recurring ANR patterns.
  • Implemented SSL certificate pinning and Android Keystore-backed encryption to secure API traffic and at-rest credentials — a baseline that carried the app through annual third-party security audits.
  • Defined the org-wide mobile-security baseline (SSL pinning, root detection, encrypted storage, ProGuard/R8 hardening) adopted across all enterprise client apps.
  • Improved API reliability through stricter contract validation, exponential-backoff retry logic, and standardized error mapping — measurably reducing retry-loop incidents and the 5xx tail in production.
