Just finished a 40-min live coding challenge for a major HFT firm: full-stack CRUD + external API + persistent DB + dashboard.
Shipped 100% working, production-ready in 26 min flat – zero AI, typed live.
My day-to-day work is with enterprise-grade, long-lived systems on Java / Spring Boot, Go, Angular
Strongly typed, self-documented, built to run 10+ years.
But when the clock is 40 min and it has to work or you’re out, Next.js 15 + Prisma + Tailwind is the fastest path that still respects structure.
If your monolith, pipeline, or cloud migration needs an architect who ships for decades but can deliver in days (or minutes), DM me.
