What I'm looking for

I'm looking for a remote-friendly role where I can own end-to-end product delivery across Flutter, web, backend, and deployment, collaborate closely with product teams, and ship scalable user-facing applications.

I've shipped Flutter, FastAPI, and Supabase products end-to-end, including a SaaS news platform serving 10,000+ monthly active users. I built its mobile UI, backend, and Next.js frontend while adding subscriptions, SEO tools, newsletters, and Razorpay payments.

At Metacrest LLP, I'm the primary engineer for a production Flutter/FastAPI application, owning UI, backend services, database design, testing, and Docker/Nginx deployment. I build resilient mobile experiences with reusable async state handling, connectivity recovery, navigation, notification scheduling, and UTC-aware backend logic.

Previously at Nexshrim Technologies, I delivered an HRMS Android app and admin dashboard for 200+ active employees, built tamper-proof Razorpay workflows with zero fraud incidents, and reduced page load times by 40%. I enjoy remote-first collaboration and shipping practical products that solve real operational problems.
