About Me

I'm Ezz, a Top Rated Plus (Top 3%) software consultant on Upwork. I specialize in helping AI startups reduce their LLM infrastructure costs through strategic optimization. My proven track record includes helping an Oxford spin-off AI startup achieve a remarkable 95.5% performance improvement in their API calls.

My expertise spans AI agent development, backend infrastructure optimization, and cost-effective LLM implementations. I've earned the Machine Learning Specialty Certificate from AWS and consistently deliver measurable results that directly impact my clients' bottom line. I write clean, maintainable code and architect solutions that scale efficiently.

When I'm not optimizing backend systems, you can find me walking, reading, or experimenting with new programming languages and frameworks to stay ahead of the curve.
