Backend systems, production failures, and learning in public.
Senior Software Engineer. 10+ years on APIs, backends, and infrastructure that have to keep working. PHP and Laravel are where I have spent the most time. They are not the whole job.

# usually working with Laravel PHP MySQL AWS Redis Docker Linux # currently exploring Vector databases, AI systems, C++, Qt, and desktop application architecture.
