What we
do best.

Three disciplines, one team. We pair senior engineers with embedded designers and project managers so your roadmap moves in a straight line — from kickoff to certified release.

/ 01

Software Engineering

Production systems engineered for scale and clarity — backends, APIs, web platforms, and infra that you can read at 2 AM.

  • Typescript · Go · Rust
  • Distributed systems
  • Observability & SLOs
/ 02

UI / UX Design

Interfaces that respect the user and the engineer. Design systems, prototypes, and pixel-tight handoffs.

  • Design systems
  • Hi-fi prototypes
  • Accessibility audits
/ 03

Project Management

Embedded PMs run the cadence — kickoffs, weekly demos, risk logs, and clear handoffs to your internal team.

  • Roadmapping & sprints
  • Risk & scope ledger
  • Stakeholder demos
02 / Process

How we
work.

A four-phase loop tuned for clarity and momentum. Every phase has a named owner, a written artifact, and a working demo at the end. Nothing ships without a signature.

01

Discovery

Workshops, audits, success metrics. We write the brief together.

1–2 weeks · Spec
02

Design

System foundations, flows, and clickable prototypes you can test.

2–4 weeks · Figma
03

Build

Sprints with weekly demos. Tests, CI, and feature flags from day one.

6–14 weeks · Ship
04

Deliver

Cutover, training, runbooks, and a 90-day certified support window.

2 weeks · Handoff

04 / The Studio

Small team.
Serious software.

Certisoft is a senior-only studio of engineers, designers, and project managers. We don't sub-contract. Every line of code, pixel, and risk memo is owned by a named person on our team — and signed off before it ships. That's what we mean by “certified”.
