I've built and maintained production fundraising experiences at GivenGain, delivering React interface changes, reusable components, responsive embedded UI, and regression-safe releases.

At DeepAlert, I improved UI response performance by 35% and reduced initial page-load time by 70% through lazy loading, route-based chunking, and Next.js dynamic imports. I also developed .NET Core APIs with PostgreSQL and led WCAG 2.1 accessibility improvements.

Across MWEB, WordApp, Fireworkx, Sharenet, and Pisval Tech, I've worked on React applications, React Native mobile products, REST and GraphQL integrations, real-time SignalR features, testing, debugging, and CI/CD delivery. My work has reduced rendering delays, deployment time, defects, and critical production bugs.

I also built StockFlow Pro, a full-stack inventory and operations platform with React, React Native, TypeScript, .NET Core, SQL Server, SignalR, React Query, Zustand, offline support, and role-based access control. I use AI-assisted tools carefully, validating generated code through manual review, debugging, testing, and regression checks.
