What I Do

Approach

I build tools that give business owners their time back. I find the manual, repetitive tasks that keep you stuck in spreadsheets and replace them with fast, reliable automation — without expensive over-engineering. With hands-on experience in both technical execution and business leadership, I bridge the gap between engineering and real-world results.
