Fractional Senior Engineering · ongoing · monthly
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.

Every item below is part of the fixed written proposal. Nothing here is an upsell.
Fixed weekly slots with visible output: reviewed pull requests, written architecture decisions, unblocked engineers, shipped fixes. Not a retainer that quietly evaporates.
System design, scaling decisions, security posture, and software architecture reviews with written recommendations your team can execute and future hires can read.
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.
Mentoring for your developers, interview support for engineering hires, and technical due diligence when you evaluate vendors or acquisitions.
01
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
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
Every week ends with a demo of deployed software and a short written update. You always know where the project stands.
04
You own the code, the infrastructure, and the accounts from day one. Handover includes documentation and a walkthrough. No lock-in, ever.
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.
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.
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.
