What I'm looking for

I’m looking for a role where I can own API and database architecture end-to-end, build reliable microservices, and improve performance with strong testing and observability—collaborating closely with product, QA, and operations to ship impactful releases.

I’m a senior software engineer with 6+ years of experience building scalable backend systems, full-stack web applications, and data processing platforms across healthcare, travel, and betting domains. I take ownership of API design, database architecture, and modern frontend development.

In my current role, I build healthcare provider verification systems with React/TypeScript and .NET/C# backed by PostgreSQL. I’ve optimized search performance through query tuning, indexing, and stored procedure improvements, and improved reliability by expanding test coverage across UI (Jest) and backend APIs (xUnit/MSTest).

Previously at Appinventiv, I contributed to BuddyBet platform launches across US, New Zealand, and Malta, working on .NET microservices enhancements and production support. I integrated payment vendors, redesigned Azure Functions and automation modules, and built Audit Automation REST APIs in .NET 6.

At Fareportal India, I delivered major backend outcomes like a RuleBook API that consolidated data for call-center agents and reduced response times by ~10x. I also led a team of 4, supported airline partner integrations, and helped drive quality using observability and testing practices.
