I work fast. I communicate clearly. I get the job done.
I’m Fahad Zakir — a Full-Stack AI Engineer based in Aurora, Illinois. I build complete solutions: model eval, prompt systems, APIs, and interfaces that real users can operate.
Teams hire me when they need someone who can sit with a messy problem, design the architecture, and still write the React and Python that ships.
