My story so far
From internships to shipping enterprise software.
I'm a Full-Stack Software Developer based in Chennai with hands-on experience designing, developing and maintaining scalable web applications. Currently a .NET Developer at Thapovan Info Systems, I contribute to enterprise applications, payment integrations, system migrations and feature enhancements that deliver real business value.
My journey began with internships focused on web development and software engineering, where I built a foundation in ASP.NET Core, AngularJS, Web APIs, databases and cloud workflows. Since then I've expanded across the full stack — leading a payment migration from Authorize.Net to Stripe, integrating modern gateways like NMI, and modernizing legacy .NET + MSSQL systems to NestJS + PostgreSQL with Supabase authentication.
I'm a fast learner, a self-motivator and adaptable to any environment. I care about clean architecture, measurable impact and shipping high-quality software — and I love collaborating with teams to solve real-world problems.
