Four lanes. One single team from diagnosis to deploy.
No hand-offs between vendors. You talk to the person designing, writing, and committing.

- TypeScript end-to-end
- CI/CD + observability

02Process
How we sync up from brief to launch.
- 01 · Discovery
We listen first. Always.
60-min call to understand business, goals, bottlenecks and north-star metric. We leave with a shared doc of hypotheses and priorities.
3-5 days - 02 · Proposal
Surgical scope, no inflated invoice.
Scope, timeline and investment per phase. You know exactly what enters each milestone — and what does NOT. No fine print.
2-4 days - 03 · Build
Weekly sprints, daily commits.
Shared Linear/Notion access, demos every Friday and a staging environment from the first deploy. You watch the product being born.
4-12 weeks - 04 · Launch
Launch is the start, not the end.
Gradual rollout, Web Vitals and funnel monitoring. Post-launch: 30 days of included hyper-care for fine-tuning on real data.
+ 30 days hyper-care
03Stack
Serious tools. No hype, no tech debt in disguise.
We pick a stack that scales — and that you can hire a dev for after we hand it off. No boutique framework lock-in.

04FAQ
Questions we stopped answering on the first call.
Yes. We operate as an outsourced squad behind your brand: deliveries in your standard, communication only with the focal point, NDAs signed. We've shipped for dozens of agencies that needed technical capacity without staffing an in-house team.
