How we work together

Three ways to engage.

Staff Augmentation

Your team. Our engineers.

1–5 senior engineers embedded in your existing team. Your processes, your tools, your sprint cadence — we plug in and contribute from day one.

Ideal for: Already have a team, need senior capacity fast

Most common

Dedicated Squad

Your product. Our team.

A full self-managed squad — tech lead, developers, QA — assigned exclusively to your product for 3–12+ months. Full ownership, full velocity.

Ideal for: Building from 0 to 1, or scaling an existing product

Project Build

Your brief. Our delivery.

Fixed scope, fixed timeline, milestone-based payments. We define the architecture, deliver working software, and hand over full ownership.

Ideal for: Clear scope, defined outcome, budget certainty

Engineering standards

What you get. By default.

Every engagement. Every project.
Non-negotiable standards.

2-week sprints

Every sprint ends with a working demo. You get Jira board access and join sprint reviews — always knowing what ships next.

Mandatory code review

Every PR requires 2 senior approvals + all automated tests passing before merge. No shortcuts, no exceptions.

Staging environments

Every feature branch gets a live staging deployment. You test before it touches production. No surprises at launch.

≥ 80% test coverage

Unit, integration, and E2E tests enforced via CI pipeline. Coverage reports attached to every build, tracked over time.

Weekly sync

30-min video call every week. Daily async updates via Slack or Teams. You're never left guessing what's happening.

Security-first

OWASP checklist, dependency scanning, secrets via Azure Key Vault or HashiCorp Vault — enforced on every project, not as an afterthought.
