Code as craft
// what shipping actually looks likeexport async function deploy(build: Build) { const checks = await runCI(build); if (!checks.passing) throw new Error("fix it first"); await rollout({ canary: 10, region: "eu-west" }); observe("p99", { under: 180 }); return { status: "live", downtime: 0 };}Ways to work together
Scoped retainers and project rates — clear deliverables, no surprises.
Project sprint
A scoped 2-4 week build: ship a feature, fix a bottleneck, or de-risk a launch. Fixed deliverables.
Monthly retainer
Ongoing senior capacity: architecture, code review, and shipping. Your team, plus one more pair of hands that ship.
Fractional tech lead
I own technical direction for your product: roadmap, hiring bar, and the hard calls. Limited slots.
Screens & shipped UI
What teams say
Yusuf shipped our payments dashboard ahead of schedule and it just worked. The kind of engineer who removes risk instead of adding it.
He took our flaky search to sub-200ms p99 and documented every decision. The most reliable contractor we have ever hired.
Pragmatic, fast, and honest about trade-offs. Our routing engine went from prototype to production in weeks.
Clean code, clear PRs, zero drama. Yusuf raised the bar for the whole team while he was with us.
Strategy call
30 minutes. Your stack, your blockers, a clear next step.
