My Story

I'm a Lead Software & AI Engineer with over 5 years of experience designing and shipping production systems across full-stack, backend, and AI domains. I've worked remotely with companies in the United Kingdom, United States, and United Arab Emirates — building scalable APIs, autonomous agent pipelines, and real-time web applications.

I co-founded Paoneers, led architectural refactors that improved system performance by 20%, and shipped MVPs from zero to production in under 3 months. Beyond engineering, I'm a technical writer and mentor — I share what I learn through blog series on DEV.to, Medium, and Hashnode, and I actively invest in growing the next generation of engineers.

I'm currently open to senior and lead remote roles globally — particularly in AI infrastructure, full-stack product engineering, or developer tooling.
