Biography
I build technology that solves real business problems — and I own it end to end, from architecture to deployment.
Over five years I have shipped e-commerce platforms, enterprise systems, mobile applications, and automated workflows that organisations depend on at scale. Most recently as CTO, I led the build of a platform serving 30,000–50,000 monthly visitors, cutting operational overhead by 60% and order processing time by 40%.
My work sits at the intersection of systems thinking and practical delivery. I design for scalability and performance, but the measure of success is always the business outcome — if it does not make something measurably faster, cheaper, or better, it is not done.
I also invest seriously in the engineers around me. Building great teams is part of how I build great products.
Open to senior full-stack and engineering leadership roles where technology is a core business function.
