Wireframes → high-fidelity prototypes in Figma. Component library and design tokens before any code is written.
03WK 4–12

Two-week sprints. CI/CD from day one, weekly demos, async standups in Slack. You see progress, always.
04WK 12+
Ship & Support
Launch with monitoring, runbooks, and a documented handoff. Optional retainer for ongoing engineering.
§ 06WHAT CLIENTS SAY
Quiet confidence, from real teams.
“
Their Node + Postgres backend is still purring along two years later with zero unplanned downtime. Clean migrations, instrumented properly, documented for our in-house team.

CTO
HEALTHCARE PLATFORM
“
We came in with a scrappy MVP and left with a production mobile app on iOS and Android. The Strapi CMS they stood up means our marketing team can ship without a deploy.
P
Founder
EDTECH COMPANY
“
HashHorizon delivered a React + Next.js product in eight weeks — on scope, on budget, with a Lighthouse score above 95. They operated like an extension of our team, not a vendor.
