not the demo.
Six years, 20+ production apps on Android and iOS. Flutter and Dart first, with backend in Kotlin/Spring Boot and Supabase — built end to end, from Postgres schema through native store release, for founders and teams in the USA, Germany, the UAE, Ireland, and India.
Chandpur, BD
Six years,
twenty-plus apps.
Senior software engineer building and shipping production mobile applications in Flutter/Dart first and foremost — 20+ Android and iOS apps across recruiting, e-commerce, healthcare, fintech, and social domains for companies in the USA, Germany, the UAE, Ireland, and India.
Equally at home directing agentic AI tools (Claude, Copilot) to build full applications end to end — frontend, backend, and infra — knowing what breaks and handling it the way a senior engineer would. Deshi Choco was built entirely this way.
Backend work in Kotlin/Spring Boot and Supabase rounds it out, from database and API design through native integrations, Play Console and App Store Connect release, and handover. Four of those apps — Referable (Customer and Business), Kingstone Comics, and JobsNavi — are live in both stores today.
Where the work happened
Senior Software Engineer
Built Kingstone Comics, a motion-comics and movie reader app (Android & iOS), and Referable, a multi-tenant referral platform (Flutter + Kotlin/Spring Boot). Currently building HottestSpot, an event-ticketing platform where creators organize events and sell tickets and admins monitor activity (Go backend, clean architecture throughout) — own the Flutter and web frontend end to end. Still engaged on a project basis.

Self-directed and client work including Deshi Choco (e-commerce, Next.js 14 + Flutter + Supabase, 10-table Postgres schema with triggers and row-level security). Technical lead on Madrasah Management and MIBD financial systems — schema design, RBAC, migrations, and code review.
