Deniz Genc
Full Stack Developer · AI Automation
Boca Raton, FL, USA
Open to freelance & contract work
Summary
Full-stack developer and AI automation specialist based in Boca Raton, Florida. I design and ship complete systems for e-commerce and SaaS products — database schema, payment integration, background jobs and the admin dashboard a team actually uses every day.
Most of that work is my own: Moygo, an AI visual-generation SaaS on NestJS and React with multi-provider image pipelines and credit billing; TurGame and Gelsin, digital-goods stores with Iyzico and PayTR payments and automated fulfilment; Parayol, a Flutter personal-finance app on an ASP.NET Core API; and a suite of 16 WooCommerce plugins covering two-factor authentication, identity verification and fraud blocking.
Alongside my own products I work with founders, agencies and e-commerce brands as a freelancer on Upwork, where I hold a 100% Job Success Score and a 5.0 rating. I turn vague ideas into concrete specs, write code the next developer can read, and stay reachable while a project is live.
