Software Design & Architecture
I help you design systems that hold up — including turning vibe-coded apps into real architecture: the right tradeoffs, clear boundaries, and a codebase where the next ten features don't slow the team down. Stack-agnostic; the architecture is what matters.
Performance & Scalability
Slow systems are usually architectural, not cosmetic. I audit and rework the parts that actually matter — data flow, rendering paths, caching, network — so your product feels fast under real load, not just in dev.
Ongoing Engineering Partnership
Long-term engineering muscle on retainer — code reviews, architectural guidance, mentorship for your team, and a steady hand on the parts of the codebase that need consistent care. Less firefighting, more compounding.
