About me
I fix bugs and build small automation tools — Python, JavaScript and SQL.
Most of what I take on is whatever is blocking you right now: a bug you've lost a day to, a report whose numbers don't add up, a task you're still doing by hand every week.
How I work — I ask two or three questions before quoting, so the price and the date are fixed and there are no surprises later. I deliver early rather than late. You get working code, setup steps written in plain English, and an honest note on anything it doesn't handle.
If it's not something I can do well, I'll say so before you order.
