01 / About
I build systems
that actually scale.
I'm Kusumeshkant Sharma — a Senior Flutter Developer in Bangalore with 5+ years delivering production cross-platform iOS and Android apps — Clean Architecture, Riverpod, BLoC, GraphQL and real-time integrations across fintech, fitness and e-commerce. I own the full mobile delivery cycle: architecture, API integration, code reviews and mentoring, through App Store and Play Store releases.
I architected the Selfe Loans app for Equitas Small Finance Bank across 900+ branch integrations and led the 150+ Health app with smartwatch sync on both platforms. As a personal project, I'm currently building Cockpit — a Flutter + Supabase app for approving AI-agent actions.

Production Flutter apps across fintech, health and e-commerce — plus two personal projects.
Cockpit
AI Agent Approval Console
HMAC + RLS
Secure by design
Mobile-first, human-in-the-loop app for approving AI-agent actions (n8n / Make / Zapier / custom agents). Signed webhook → FCM push → one-tap approve / edit / reject → authenticated callback to the agent, backed by an append-only audit trail. Supabase Postgres with row-level security and transactional Edge Functions enforcing HMAC-signed webhooks and idempotent decisions.
