What I'm looking for

I'm looking to build production backend and AI systems where I can own architecture, ship end-to-end features, and work on practical, cost-conscious infrastructure.

At Techmasworld Infotech, I lead backend architecture for a service marketplace and deliver full-stack features across live client projects using Node.js, Laravel, PostgreSQL, and Next.js.

I've integrated PhonePe, Razorpay, and PayPal payments, built voice AI backends with Whisper and Chatterbox, and engineered real-time video streaming for a YOLO-based security detection pipeline. I also deployed Grafana and Prometheus to replace manual log inspection with real-time VPS monitoring.

I'm building Weave, a multi-provider AI agent SDK, alongside Nodebase workflow automation and Noetalm, a grounded AI research platform with agentic RAG, multi-provider LLM routing, and async document ingestion.
