Oyeleke Oluseun Emmanuel

Passionate Developer,
Lifelong Learner

I'm a Full-Stack Software Engineer based in the UK, with deep expertise in PHP & Laravel, Python, React and modern web technologies. I love turning complex problems into elegant, scalable solutions.

Over the past 5+ years I've shipped production-grade HR platforms, accounting systems, AI-powered tools and REST APIs used by thousands of people. My recent work includes an AI CV tailoring application built with Python (FastAPI) and React that uses OpenAI to help candidates land their dream jobs.

When I'm not coding, I'm contributing to open-source, mentoring junior developers, or exploring the latest in AI/ML tooling.
