Tech Stack

Boring in the best way

We use battle-tested tools that have stood the test of time — not hype-driven frameworks that'll be deprecated next quarter.

From brief to shipped

01 — DISCOVERY

Scope & Architecture

We audit your requirements, map the data model, and write a technical brief before any code gets written. No surprises later.

02 — BUILD

Weekly Sprint Cycles

Two-week sprints with a demo at the end of each. You see working software constantly — not a big reveal at month three.

03 — REVIEW

Code Review & QA

Every PR reviewed, every feature tested. We write RSpec and Cypress tests alongside feature code — not as an afterthought.

04 — SHIP

Deploy & Support

Zero-downtime deploys, monitoring setup, and a 30-day support window after launch. We don't disappear after handover.
