What I'm looking for

I'm looking to build production software where I can contribute across Flutter and full-stack development, work on scalable systems and AI-assisted workflows, and grow through mentorship, peer feedback, and collaborative delivery.

I've built production-grade full-stack applications at Engagetal Solutions and CareFi’s Aldun App, translating product requirements into maintainable software through collaborative development, peer reviews, and iterative delivery.

At CareFi, I launched a real-time geotagging feature that achieved 95%+ tagging accuracy and reduced manual input by 30%. I also improved the PayU payment flow to help reduce user drop-offs by 15–20% and integrated PostHog analytics for feature-level user insights.

Previously at CodexVeer, I developed reusable Flutter components and scalable Node.js/MongoDB APIs handling 1,000+ concurrent requests under 200ms latency. I also built BuildBuddy, an AI coding assistant using LangGraph, FastAPI, and LLMs to automate architecture, implementation, and validation workflows.
