MFS Yazılım is an engineering team that takes production-floor problems seriously. We don't run slide decks; we build systems that ship, scale and stay alive long after we hand them over. Every project is a series of technical decisions, made on solid foundations and documented for the team that will inherit them.
Partnership is the bar — not a vendor billing hours, but a team that treats your product like it's our own. We treat AI as a sharp tool, not a goal in itself. We build what you need today, and document it so tomorrow's takeover is not a loss.
Mustafa Şen is the founder and lead engineer of MFS Yazılım. For years he has shipped production-grade systems across AI automation, LLM integration and Next.js / TypeScript stacks. From Hetzner to Kubernetes, from RAG architecture to DevOps discipline — he signs off on every technical decision end to end. He works directly with clients; there are no middlemen and no surprises.
We're partners, not vendors. Your Slack is open, you talk to engineers directly. We work like an extension of your team — no dropped calls, no lost emails, no proxy account managers.
Tested, reviewed, documented code. We don't stop at the demo; we guarantee it keeps running months into production. Lighthouse 90+, SLO-driven infrastructure, real ops discipline.
Fixed price, fixed scope, fixed delivery date. Weekly demos, open progress — never the 'what are they doing?' question. Invoices arrive without surprises.
A working demo by end of week one. No months of spec docs — live code, real UI, real feedback. Fast iteration without trading away engineering quality.
