What I'm looking for

I'm looking to take ambiguous, resource-constrained product problems from requirements through architecture, development, and deployment, especially for AI-powered platforms, backend systems, and full-stack web or mobile products.

I've owned end-to-end technical delivery at SPAS Computers Pvt. Ltd., gathering business requirements and designing, building, and deploying web platforms. I also launched an online auctioning platform for Proaucs from requirements through production.

As a freelance full-stack developer, I've built ecommerce, on-demand home services, and mobile products with payments, authentication, booking workflows, live location tracking, support chat, and admin panels.

My recent work includes Diya Company Brain, an enterprise knowledge graph platform using Neo4j, LangGraph, Cognee, and source-cited proof-chain answers. I've also built Rayn, an AI legal dispute-resolution platform combining LoRA fine-tuning with agentic RAG.

I take ambiguous requirements from scope and system design to shipped products, using AI-assisted development workflows alongside Python, TypeScript, React, Next.js, cloud infrastructure, and production APIs.
