A PROBLEMsolverBY NATURE
Before I ever wrote a line of code, I was taking things apart to understand how they work. Fixing cars in the garage. Soldering circuits at the kitchen table. Building furniture from raw lumber. That same curiosity — that need to figure it out — drives every project I take on.
When I encounter a problem, I don't reach for the manual first. I reach for the tools. Whether it's debugging a complex API integration or rewiring a circuit board, the approach is the same: understand the system, find the bottleneck, build the fix.
