If your project needs more than someone who writes code to spec โ€” if you need someone who can architect the solution, own the delivery, and still be there for support six months later โ€” that's the role I take on.

I manage scope, timelines, and stakeholder expectations as carefully as I manage the codebase itself. Depending on what your project needs, I can work as a hands-on senior engineer, a solution architect, or a long-term technical lead. I'll tell you honestly, early, if I'm the right fit for what you're building. Send me your project scope and I'll respond within a few hours.
