About me

Engineering with
intent.

I'm a full-stack software engineer with 5 years of hands-on experience designing and shipping production systems — from greenfield SaaS platforms to complex enterprise migrations. My work sits at the intersection of engineering excellence and product thinking. I don't just build features; I architect outcomes.

Over the last 5 years, I've worked across the full stack — from crafting pixel-perfect React interfaces to designing distributed backend systems on AWS. I've shipped products used by tens of thousands of users, led architecture reviews, and mentored engineers to write better, more maintainable code. My philosophy is simple: write code that your future self will respect, design systems that scale without drama, and always ship with intent.

Philosophy

How I think about engineering.

Clean code is non-negotiable

I write code that my team can read, review, and maintain without a decoder ring. Naming matters. Structure matters. Documentation matters.

Design before you build

Every decision I make starts with understanding the system boundary. I draw before I code. This saves weeks.

Speed without quality is debt

Fast shipping is a virtue. Shipping broken things is not. I move fast within quality guardrails — not around them.

Ship to users, not to repos

Code that's not deployed is theory. I prioritize getting things to production safely and iterating from real feedback.
