What I'm looking for

I’m looking for a full stack role where I can own API design and microservices with .NET, build responsive Angular/React UIs, and drive measurable performance gains through SQL tuning, modernization, caching, and CI/CD automation.

I’m a Senior Full Stack Software Engineer with 3.8 years of experience building scalable web applications using C#, ASP.NET Core, Angular, and React. I focus on delivering reliable systems through strong API design, SQL Server performance tuning, legacy .NET modernization, and microservices architecture.

In high-throughput financial and enterprise environments, I’ve architected and optimized backend services for forex trading and ad-tech pricing. For FX Bazzar, I built transactional and routing API modules and optimized order matching and SQL Server stored procedures, reducing order placement API latency to under 100 milliseconds. At The Times of India (Response IT Department), I refactored a core calculation engine, fixed race conditions and SQL Server deadlocks, and improved system availability to 99.9% uptime.

I also build practical, production-ready solutions end-to-end. I modernized ad publishing queue processing with caching strategies to reduce database read load by 50% during peak traffic, developed secure Web API-driven chatbot integrations for Motilal Oswal Asset Management, and led .NET Framework 4.x to .NET Core 6/8 migrations while improving database batch performance and automating US Tax workflows. My personal project, AIBOS, reflects how I combine ASP.NET Core, React, PostgreSQL, Redis, JWT authentication, Docker, role-based access control, EF Core migrations, CI/CD, and unit tests to ship SaaS-ready platforms.
