About Me

With over 4 years of experience crafting digital solutions

I create autonomous AI agent systems, scalable full-stack applications, and cloud infrastructure that delivers real business outcomes across fintech, e-commerce, mobile, and data-driven platforms.

I bring both the technical depth to ship agentic workflows and a formal background in economics and agricultural systems thinking, combining software engineering with domain understanding of capital flows, resource allocation, and data-driven decision making.

With experience across multiple technologies and frameworks, I approach each project with a focus on clean code, scalable architecture, and measurable outcomes.
