What I'm looking for

I'm seeking remote or on-site opportunities across India where I can build secure, scalable backend systems, distributed APIs, authentication platforms, and AI-powered applications.

I architected SmartID at Shoptaki, a production-grade authentication platform securing four microservices with PASETO v4, Ed25519 keys, email OTP, refresh-token rotation, and JWKS.

I also engineered a four-service Node.js/Express, Prisma, and PostgreSQL backend with Docker Compose orchestration, plus an API gateway that centralized token verification and rate limiting while removing duplicated authentication logic across services.

Previously at Replete Software Solutions, I delivered five-plus production full-stack applications as a sole engineer across requirements, architecture, implementation, QA, and release. I built behavioral analytics for user drop-off patterns and re-architected a Python monolith into decoupled microservices to reduce backend latency.

I'm focused on scalable APIs, distributed systems, identity and access management, and practical AI applications, including RAG pipelines for PDF search and NLP-based resume matching.
