I build scalable systems that survive high traffic — and the teams that keep them alive.
Who I am
# Results-driven Senior Software Engineer with 8+ years leading technical strategy, end-to-end delivery, and operations. Deep across the full stack — PHP/Laravel on the back, React/Next.js on the front — with a track record of high-performance web solutions in high-traffic environments. Strong in team leadership, systematic problem-solving, and turning messy operations into automated, reliable systems.
I lead small, high-trust teams and like the unglamorous parts: on-call rotations, runbooks, code reviews, and automating the work nobody wants to do twice. I've taken services to 99.8% uptime, built an ERP that removed 70% of manual ops, and shipped landing pages that absorb 10K+ signups a week.
Equally at home translating architecture trade-offs for the C-suite and pairing with a junior on their first PR. I care about systems that don't break and teams that don't burn out.
