Cenk Y.

If your business has outgrown packaged software, I build what fits, custom, end-to-end solutions designed around your exact processes. Since 2006, I've delivered bespoke software across 8+ countries for clients ranging from global enterprises to funded startups. I currently maintain active support contracts with Vodafone and Philip Morris International, and have built and shipped products in logistics, fintech, agriculture, manufacturing, real estate, maritime, and SaaS. What I bring that most developers don't: — I've sat inside IT departments of large corporations, so I understand how decisions are actually made and what "production-ready" really means. — I've founded multiple software ventures of my own, so I understand the pressure of building something that has to work from day one. — I work across the full stack: mobile (Expo / React Native), web, desktop, backend APIs, cloud infrastructure (Azure, AWS), databases (MSSQL, Supabase, PostgreSQL), and third-party integrations (Stripe, open banking, ERP systems, barcode/IoT, and more). — I own physical iOS, Android, macOS, and Windows devices — every build is tested on real hardware. I work in structured weekly milestones with written updates, clear communication, and no surprises. My clients stay with me long-term because the work is done properly the first time. If you have a project that needs to be built right — not just built fast — I'd like to hear about it.
