Hi, I'mFehmi Can Ay
I design and ship production systems end-to-end — from pixel to pipeline. Two SaaS products built from scratch, and counting.
About Me
Full-stack software engineer with 4+ years of experience designing and shipping production systems end-to-end. Architected and built two SaaS products from scratch — a multi-tenant e-commerce platform and a nationwide event aggregator — owning the full stack from frontend to backend, infrastructure, and CI/CD. Strong grasp of software architecture and scalable system design, with hands-on expertise in Next.js, NestJS, TypeScript, MongoDB, OAuth/JWT authentication, third-party API integrations, and self-hosted deployments. Effective at both leveraging AI tools to accelerate development and building AI-powered features into production products.
