Building AI, SaaS, & Scalable Architectures.
Designing, building, and scaling high-performance digital products end-to-end.
About Me.
From HTML in Grade 9 to AI-powered SaaS — the journey of a builder.
My journey into software engineering started in Grade 9 — with a basic HTML tutorial, a slow internet connection, and an insatiable curiosity about how the web worked.
What started as copying code from tutorials became an obsession with building things. I taught myself C++, dived into competitive programming, then discovered the power of full-stack web development. Every new technology wasn't just a skill to learn — it was a tool to solve real problems.
Today, I specialize in building production-grade AI systems and scalable SaaS platforms. As the founder of multiple startups, I've learned that great engineering isn't just about writing code — it's about designing systems that scale, building products that users love, and solving problems that matter.
I believe in shipping fast, iterating often, and engineering for resilience. Every project I take on is built with production-readiness in mind — from the first commit.
