Embedded build & leadership
Embedded as a senior engineer, technical lead, or architecture partner. PRs, design docs, code reviews, and the decisions that keep delivery on track.
1 – 2 weeks
Scale & hand off
We harden the system for growth, leave ADRs and runbooks, and I run a knowledge-transfer session per engineer. Your team owns it cleanly after I'm out.
Understand the goal
We start from your business goal, not the technology. What you need, by when, and what success looks like.
A clear plan
I propose a plan with scope, timeline, and cost before a single line of code. No fine print.
We build it
I execute with frequent updates in plain language. You always know where your project stands.
Delivery & support
We ship it to production, I walk you through how it works, and I stay available for what comes next.
Async-friendly, timezone-fluent (UTC−3, overlaps EU and US East).
What they say.
From engineers, leads, founders, and clients across a decade of shipping.
