Fractional Senior Engineering · ongoing · monthly

Senior judgment on tap, without the senior hire.

A staff-level engineer costs six figures and six months to hire. This gets you the judgment part on a monthly basis: architecture, hard problems, AI strategy, and a calmer engineering team.

from €4,500/mo2 days/week equivalent · cancel monthly

This is for you if

  • Your team ships features but keeps hitting architecture decisions nobody feels safe making
  • You have AI ambitions and need someone who has actually put LLM features into production
  • You're a non-technical founder who needs a trustworthy technical counterpart for vendors, hires, and investors
  • An agency builds for you and you want independent eyes on what they deliver

What you get

Every item below is part of the fixed written proposal. Nothing here is an upsell.

A standing weekly cadence

Fixed weekly slots with visible output: reviewed pull requests, written architecture decisions, unblocked engineers, shipped fixes. Not a retainer that quietly evaporates.

Architecture and code review

System design, scaling decisions, security posture, and software architecture reviews with written recommendations your team can execute and future hires can read.

Hands-on hard problems

The bug nobody can reproduce, the migration nobody wants to touch, the AI feature that works in the demo and nowhere else. Senior hands, not just senior opinions.

Team leverage

Mentoring for your developers, interview support for engineering hires, and technical due diligence when you evaluate vendors or acquisitions.

How it runs

01

Intro call

30 minutes, free. We establish what you're building, what's blocking you, and whether we're the right fit. If we're not, we'll say so and point you somewhere better.

02

Written proposal

Within 48 hours you get a fixed scope, a price, and a timeline in writing, including what's explicitly out of scope. No surprises invoiced later.

03

Weekly working software

Every week ends with a demo of deployed software and a short written update. You always know where the project stands.

04

Handover & ownership

You own the code, the infrastructure, and the accounts from day one. Handover includes documentation and a walkthrough. No lock-in, ever.

Fair questions

How is this different from hiring a freelancer?+

Continuity and altitude. A freelancer executes tickets; this engagement owns outcomes across weeks: architecture, review, mentoring, and delivery. And it comes with the studio's standards: written decisions, monitored deploys, honest pushback.

What if we need more than two days a week?+

The engagement scales up or down with one month's notice. Bursts around launches are normal; sustained full-time demand usually means it's time to hire, and we'll help you do that instead of milking the retainer.

Is there a minimum commitment?+

One month. The first month is deliberately structured to produce visible value fast (an architecture review and a prioritized findings list in week one), so you can judge the fit quickly.

The studio also builds: Web applications & SaaS · Mobile apps (iOS & Android) · RAG & knowledge systems · Agentic workflows & AI assistants · Chat & voice bots · APIs & integrations· and more. If your project doesn't fit this package neatly, describe it anyway. Scope bends; standards don't.
