4+ years architecting highly scalable, high-throughput distributed systems. Expert in microservices, robust backend APIs, and React frontends built for enterprise-scale demands. Based in Vadodara, India.
Engineering systems that scale.
I'm a Software Engineer with 4+ years of hands-on experience building distributed, high-throughput systems. My core strength is .NET Core / ASP.NET Core backend development paired with React.js frontends — a combination that lets me own features end-to-end.
At Sikka.ai, I helped serve 100,000+ daily API requests for enterprise healthcare and insurance clients while cutting load times by 30% and boosting user engagement by 40%. At valcz.com, I built a full observability stack using OpenTelemetry — reducing MTTR by 30% and achieving 90% code coverage through automated CI/CD pipelines.
I care deeply about clean architecture, rigorous testing, and systems that are built to last — not just to ship.
My technical arsenal.
A focused stack built through real-world production experience — chosen for reliability, scalability, and enterprise fitness.
