Philosophy
How I think about software
01
Problem First
I don't start with a familiar stack, I start with the problem: studying the domain, the edge cases, and what's already been tried until I understand what's actually failing and why.
02
Fit, Not Trend
I bring in whatever genuinely fits, proven patterns, new frameworks, AI-assisted workflows, filtered through critical thinking instead of trend-chasing. The tools serve the solution, not the other way around.
03
Production Ownership
I own the whole lifecycle, from database design to UI implementation to deployment, taking applications from initial architecture through to production for real users.
