Programs

Four ways to engage. One that we politely decline.

We map almost every conversation onto one of four engagement types. Picking the right one in the first week saves three weeks of friction later. The fifth type — "you bring requirements, we bring developers" — we don't do; the reasons are at the bottom of this page.

Every engagement begins with a free 30-minute call. If we're not the right studio, we'll point you at someone who is — usually with a name and a warm intro.

Greenfield Build

/01

New product, from spec to production

Greenfield Build

A complete custom platform: data model, API, persistence, auth, deployment, frontend. Most often a SaaS or an internal tool.

  • Written technical proposal (8–14 pages)
  • Schema, API contract, ER diagram
  • Backend (Laravel / Symfony / vanilla PHP)
  • Postgres + Redis, prod-ready
  • Front-end interface (8–12 templates)

Legacy Modernization

/02

Legacy app, made workable again

Legacy Modernization

Your existing app works, mostly, but new features are taking longer than they should and people on your team are afraid to touch certain files. We rebuild from inside out.

  • Written audit (8–14 pages)
  • Risk-ranked refactor plan
  • Test harness retrofitted around legacy code
  • Strangler-pattern rebuild of identified hot zones
  • CI/CD if not already in place
€11,800.00
from · 8–12 weeks

Performance & Scale

/03

Performance and architecture

Performance & Scale

A focused engagement: a slow API, a database that has outgrown its primary key strategy, a queue that's started backing up. We measure first, then change one thing at a time.

  • Profiling: APM traces, query plans, p99 response
  • Written report ranking interventions by ROI
  • Implementation of top 3 interventions
  • Load tests before / after
  • Capacity planning notes for the next 12 months
€8,500.00
from · 4–6 weeks

Care Plan

/04

Retainer for software in flight

Care Plan

Monthly retainer for ongoing engineering: bug fixes, small features, security patches, on-call. Four tiers, transparent hour budgets, no roll-over expiry beyond 90 days.

  • 6 / 14 / 30 / 60 hours per month, four tiers
  • Bi-weekly status email
  • On-call (Active and above)
  • Quarterly architecture review
  • Cancel any month, prorated to the day
€1,400.00

And the one we politely decline:

Pure body-shop or staff-augmentation engagements — "we have the spec, we just need a developer for three months". We tried it for two years. The work was less interesting, the outcomes were worse, and the writing-down-decisions habit (which is most of what makes our work different) doesn't happen when we're inside someone else's process. If that's what you need, we keep a list of three studios in Andalusia we'd trust and we'll send you names.
