I build reliable Node.js backend services for healthcare and B2B SaaS.
IndiaWhat I'm looking for
At AthanSys HealthCare, I build RevSync’s Node.js/Express backend, delivering REST and GraphQL APIs for B2B CRM workflows, sales pipelines, and support operations. I designed a PostgreSQL, MongoDB, and Elasticsearch architecture that improved data retrieval speed by about 40%.
I optimize production services handling 10K+ daily requests, reducing GraphQL latency by about 35% and SQL execution time by about 30%. I also build event-driven workers, Redis caching, secure authentication, real-time WebSocket updates, and Python/FastAPI services, including LangChain RAG integrations and an automated GitHub pull-request reviewer that cut review time by about 50%.
