Full Stack Developer
Fiverr • Vollzeit
Feb 2022 - Present • 4 yrs 7 mos
Since going independent, I've focused on full stack and AI-integrated development for clients across web, mobile, and SaaS products. This has included building multi-tenant backend systems with proper data isolation, integrating AI/LLM APIs (OpenAI, Claude) into production chatbots and voice agents, and developing REST APIs and database architecture for SaaS platforms from the ground up. I handle projects end to end — architecture, backend, frontend, and deployment — and work directly with clients to turn a rough product idea into something usable and scalable.
