What we actually do
We build and ship production software. That includes web platforms, mobile apps, internal tooling, and AI features — usually as a dedicated squad embedded with a client team, sometimes as a single senior engineer plugged into an existing codebase. We are deliberately narrow: we only take on work we are confident we can deliver at the standard our clients expect.
Alongside the engineering practice, we run an AI Training offering for frontier-model teams: domain experts producing the human data in the loop — RLHF preferences, SFT demonstrations, red-teaming, and model evaluations. Different buyer, same bar: senior people, timezone-aligned, no tier surcharges.
Why we exist
The usual outsourcing model trades cost for coordination friction. You pay less per hour, but you pay more in lost context, timezone gaps, and engineers who change every quarter. We built SONNET CODE around the opposite default: engineers who stay on your project, overlap with your working day, and communicate the way a senior hire on your own team would.
How we work
Every engagement starts with a short discovery call where we agree on scope, team shape, and how we'll measure success. From there we onboard in days, not weeks, and run in your existing rituals — your standups, your PR process, your Slack. We write production code from week one and demo live every week.
Our three-step process and our six commitments are the only contractually important bits outside of the SOW. We keep the rest of the paperwork to the minimum it takes to ship.
Who we're a fit for
- Product teams that need senior engineers quickly and cannot wait three months for a full-time hire.
- Founders building the first version of a product who want engineering judgment, not just execution.
- Companies with an existing team that need a specialized skill set — AI/ML, mobile, data — for a defined slice of work.
