About Me
Md Abdus Salam Suhag
I'm a Full Stack & Backend Developer with 1.5+ years of professional experience, focused on building scalable, secure, and high-concurrency production systems. I work extensively with Node.js, TypeScript, Express.js, MongoDB, PostgreSQL, Redis, BullMQ, Elasticsearch, AWS, and Docker, alongside modern frontend frameworks like React.js and Next.js.
My hands-on experience includes engineering Real-Time Live Shopping & Auction Platforms, multi-vendor eCommerce marketplaces, UK tradesperson lead engines, and on-demand service booking apps. I specialize in Stripe Connect split payouts & escrow, native In-App Subscription verification (Google Play StoreKit 2 & App Store), WebSockets clusters, AI API integrations (OpenAI, Gemini, Agentic AI), and AWS/Docker cloud deployments.
