Post-MVP and shipping, but no senior engineer owning the system? That's the stage where codebases quietly rot and velocity dies. I prevent that.

A fixed weekly block of senior engineering, every week:

Feature development on your React/Next.js/PostgreSQL stack

Architecture decisions and technical roadmap, thinking from design to deployment

Code review that levels up your existing team

Performance and reliability ownership: 40-60% gains and zero-downtime deploys are my track record, not my pitch

Why fractional works: most post-MVP startups need senior judgment consistently, not 40 hours of it. You get the judgment, the shipping, and the accountability at a fraction of a senior hire's cost.

Async-first, weekly sync call, monthly summary of what shipped and what's next. Cancel monthly. I keep the engagement by being worth it, not by lock-in.
