B Manoj Kumar

I’m a Senior Full Stack Engineer who builds and scales real world products—from custom CMS platforms powering enterprise websites to AI chatbots that understand context.
With 4+ years across the full stack, I’ve architected backend systems, optimized frontend performance, and integrated AI/ML solutions where performance, cost, and UX matter equally.
I build production applications using React, Next.js, and Node.js serving 200K+ monthly visitors; design scalable backends with PostgreSQL, MongoDB, REST APIs, and multi tenancy; and develop AI solutions using RAG architecture, vector embeddings, and LLM integrations. I’ve also optimized infrastructure and code, recently reducing a client’s cloud costs by 40%, and I enjoy mentoring developers and leading technical decisions.
My recent work includes building a custom CMS from scratch Node.js, PostgreSQL, Prisma, developing a multi tenant RAG based AI chatbot with semantic search, improving Core Web Vitals for high traffic apps.
