About me

I am a senior backend engineer and tech lead with more building reliable, well-documented systems for travel and e-commerce, mostly with Laravel and PHP. I design how backend systems are structured and I own them from the first line of code through to production and ongoing support.

I care a lot about correctness and clarity. Exact values, audit logs, rules backed by automated tests that prove they hold. I still write the hard, high-stakes code myself.

My best work is where I have real ownership, genuinely difficult problems to solve, and the chance to grow both the systems and the people around me.
