About
Associate Technical Lead with 6+ years of experience building production AI, backend, cloud and distributed systems.
I currently lead backend engineering for a production AI-powered healthcare platform using Python, FastAPI, Celery, PostgreSQL, Redis, AWS EKS and Kubernetes. My work includes Agentic AI, RAG, LLM integrations, tool calling, structured outputs, asynchronous processing, API design, evaluation workflows, caching, retries, observability and production reliability.
I have strong experience taking features from architecture and design through implementation, testing, deployment and production support. I regularly lead technical discussions, review pull requests, mentor engineers and work across backend, frontend, product and platform teams.
Previously at WSO2, I worked on enterprise Java and cloud systems including WSO2 Identity Server and Asgardeo, REST APIs, distributed and event-driven architectures, OAuth/OIDC/SAML, webhooks, multi-tenancy, AWS deployments and performance optimization.
My broader stack includes Python, FastAPI, TypeScript, Node.js, React, PostgreSQL, Redis, AWS, Azure, Docker, Kubernetes, Helm, Terraform and CI/CD.
I’m particularly interested in Senior AI/GenAI Engineer, Senior Backend Engineer, Technical Lead, Cloud Engineer and AI-native Full-Stack Engineer roles where I can combine hands-on engineering with architecture and technical leadership.
