About

One engineer. Twelve years. Zero hand-offs.

I'm Golam Mostafa. I've been shipping production web software since 2014 — first as a freelance full-stack engineer, then through my studio, and now through saify.dev: productized infrastructure for the agentic web.

Over 2,000 buyers run my marketplace code in production. On Upwork I hold Top Rated Plus — the top 3% of talent — on long-term Next.js, dashboard, and SaaS MVP contracts. That track record is the warranty on everything sold here.

In 2025 I went deep on the agent protocols — MCP first, then ACP and UCP as agentic commerce went from demo to revenue. saify.dev is where that work ships: real servers, real checkouts, real docs.
