Professional Summary
- Designed and delivered 10+ enterprise-scale applications end-to-end — US payroll, supply chain, and HR platforms — as sole or primary engineer from database schema through production go-live.
- Built and deployed 30+ small-to-mid scale web and desktop applications across healthcare, e-commerce, ed-tech, and modular kitchen domains — spanning monolithic, modular, and cloud-hosted models across Azure, AWS, IIS, GoDaddy, WinHost, and ctrl+s VM.
- Proactively identifies improvement opportunities beyond assigned scope — initiated and delivered frontend optimisation (4–6s → 2–3s load, 15–25 → 8–9 requests), automated tax correction replacing monthly manual effort, and closed 10–15 unnecessary requirements before development.
- Trusted go-to engineer for the hardest problems: security vulnerabilities, production outages, legacy refactors, and complex payroll tax logic that carries real financial risk.
- 13+ years of end-to-end delivery across US payroll, supply chain, healthcare, property & HR management, e-commerce, and ed-tech — enterprise products, freelance builds, and international client engagements across India, Netherlands, and UK.
- Equally strong on backend (.NET Core, Web API, Azure) and frontend (Angular, Bootstrap, responsive UIs) — not just one or the other.
- 2+ years of disciplined AI-augmented development (GitHub Copilot, Claude Code, ChatGPT) — directing, questioning, and correcting AI output to maintain engineering integrity.
- Worked directly with US and offshore clients across full SDLC — from requirements through production deployment.
