// about the architect
I've spent 12+ years solving complex infrastructure challenges — not chasing frameworks. My work centers on Laravel and .NET Core backends that don't fall apart under load, cloud architectures that teams can actually understand, and the kind of code reviews that make junior developers better.
My focus is on impact, not on technology for its own sake. Whether it's a serverless system on AWS or a hexagonal monolith in Laravel, the decision is always the same: what truly solves the problem at the right scale?
