What sets us apart

We focus on production, not PowerPoints. Every project runs from discovery through sprints to maintenance, with team continuity. Practices: automated tests, code review, CI/CD, monitoring.

/* how_we_think */

Four principles we keep in mind

Not a poster for the wall — four things that actually drive our decisions in projects.

// 01

Code, not slides

Every architectural decision ends in a commit, not PowerPoint. Slides come when we hand a report to the client — not while building the product.

// 02

Ship, then iterate

First version in production in 8-12 weeks, then learning on real users. 80% shipped beats 100% sitting in Jira.

// 03

Honest trade-offs

We'll tell you what NOT to do when the choice is bad for your business. We don't sell microservices to a three-person MVP startup.

// 04

Long-term thinking

Average partnership runs 18 months. We write code we'll still read in three years — because we usually still maintain it.

/* timeline */

Tech stack

We don't try to know everything — we know what we regularly ship to production. Tech choice is always driven by the problem, not fashion.

AI-assisted development

AI is a power tool, not a substitute for thinking. We use it where it shortens our work without compromising quality — and we keep a human eye on everything we shouldn't hand to a machine.

> ai_assisted

Where AI helps

  • Boilerplate, CRUD, scaffolding
  • Test generation (unit and integration)
  • Exploring new libraries and APIs
  • Code documentation and ADRs
  • Refactoring and bulk renames
  • First drafts of database migrations
  • Preliminary code review (assist)

> human_only

Where humans stay in charge

  • Architecture and key technical decisions
  • Code review before merging to main
  • Business logic and edge cases
  • Security review and threat modeling
  • Performance critical paths
  • Client communication
  • Final production deploys
