Not an agency. Not a freelancer. Something better.
The software market is full of agencies that sell senior talent and deliver junior work. I built my practice to be the alternative — focused, experienced, accountable.
Senior engineer on every line
I don't delegate. Every architecture decision, every code review, every critical path — that's me. You're not paying for junior work disguised as senior output.
I've been the client too
I build and operate 3 production SaaS products myself. I know what bad architecture costs at 2am. That perspective shapes every decision I make on your project.
Focused, not fragmented
I work with a small number of clients at a time. Your deadline gets real priority, not the scraps between 12 other projects. When I commit, I'm in.
Your next project
starts with a conversation.
Tell me what you're building. I'll tell you if I can make it exceptional. No pressure, no sales script — just an honest engineering conversation.
