What I'm looking for

I work directly with clients to translate ambiguous business problems into agentic AI architecture, taking systems from first principles through live deployment. I value direct engagement and full ownership of outcomes.

At Vigilant IT Solution, I engineer production AI systems where LLMs are the runtime—not the feature. I built a self-healing SQL engine that reaches 100% autonomous transaction success and a security middleware layer that has recorded zero successful jailbreak attempts in production.

I created Miracle OS from scratch as its sole architect and engineer. Its 10+ live AGI modules span accounting, property management, hospitality, HRM, marketing, and fleet operations.

At BAQARA, I founded and built a mobile-first logistics and inventory platform for cooperative dairy farmers, taking it from architecture through production. Its supply chain technology implementation across 1,200+ farmers received the Second-Best Dairy Processor Award 2022 from the World Bank.
