What It's Like Working With Me
A few things clients consistently mention after we've worked together.
I communicate in plain English
No jargon, no lengthy technical reports. You get clear updates, honest assessments, and straight answers. Even when the answer is 'that's going to cost more than you think.'
I own the work end-to-end
I don't hand off to a team of juniors. From the first line of code to the final deploy, it's me. That means accountability and a consistent quality bar throughout.
I flag problems before they become incidents
16 years teaches you to recognize early warning signs. I proactively surface risks, performance issues, and potential blockers before they hit production.
I leave the codebase better than I found it
I don't accumulate technical debt. Every feature I ship is clean, documented, and maintainable. Your next engineer will thank you.
