What I'm looking for

I'm looking to build scalable, secure production systems where I can own architecture through deployment, solve backend and performance challenges, and work directly with stakeholders on meaningful products.

I've delivered backend services and frontend modules for Karnataka Labour Welfare Board's scholarship and contributor platform, serving 396,915+ students and 32,657+ registered industries. I build secure Node.js, NestJS, TypeScript, React.js, and Next.js applications with REST APIs, JWT authentication, RBAC, Redis caching, optimized databases, and Dockerized production deployments.

At Litspark Solutions, I own delivery from architecture and requirements through CI/CD, deployment, and long-term production support. I've also built logistics, HR automation, and investor-service platforms, integrating payment gateways and designing reliable workflows for high-traffic business systems.
