Product Engineer and founder of DBSolutions Lab. I spent 14 years in industrial and logistics operations before going full-time into code — and that's what shapes how I work: I'm not guessing at the problems, I lived them on the operations floor and now I build the software that fixes them. I own the full cycle, from problem to deployment, across web and mobile.
