What I'm looking for

I'm looking to build secure, scalable full-stack and AI-powered products, with opportunities to work on backend systems, real-time workflows, cloud deployment, and production-ready software.

At Avsys International India, I build Python, Django, Django REST Framework, and FastAPI microservices for enterprise web, simulation, and monitoring applications. I deliver secure REST APIs, real-time WebSocket workflows, database-driven modules, and responsive React.js interfaces.

I've contributed to a real-time simulation platform for live data ingestion, tracking, scan workflows, reporting, and visualization-ready delivery, while also supporting an AI computer vision system with OpenCV-based processing and activity tracking. My work includes JWT access control, RBAC, PostgreSQL and MySQL optimization, Redis caching, Docker, AWS deployments, CI/CD, and production troubleshooting.

I also built AI-powered FinTech risk and fraud intelligence workflows using FastAPI, React.js, PostgreSQL, Redis, vector databases, OCR, NLP, embeddings, semantic search, and RAG. Earlier, I developed media streaming and real-time e-commerce platforms, improving performance, scalable deployment, and secure user experiences.
