I developed a full-stack digital goods marketplace using NestJS and Next.js. The platform included product listings, order management, secure payment workflows, real-time buyer-seller chat, dispute resolution, JWT authentication, role-based access control, and a complete admin panel. I also optimized real-time performance with Redis and WebSockets and deployed the project using Docker and GitHub Actions.

I worked as a backend developer building scalable APIs, AI-powered backend workflows, Web3 authentication, blockchain event indexing, smart contract integrations, and crypto payment systems. I integrated OpenAI API, Infura, Alchemy, Solana Web3, Helius, and DeFi protocols such as Uniswap, 1inch, Jupiter, and PumpFun. I also optimized databases, implemented CI/CD pipelines, wrote Jest tests, and monitored production services with PM2 and Grafana.

I also configured Nginx, SSL, reverse proxying, load balancing, Docker, PM2, and built crypto arbitrage and analytics bots.
