Jason Sellers · Fractional Staff Engineer

You're moving fast. You need senior judgment—without the full-time hire.

If you're early-stage, you're making big technical decisions under time pressure: what the data model should look like, how APIs should evolve, what "good" reliability looks like, what to build now vs later, and how to set an end state the team can align to.

I'm a fractional Staff Engineer who helps you set direction and pressure-test architecture, migrations, and reliability—so you ship faster with fewer surprises.

We'll map your top risks and next steps.

This is usually what's going on

The product works, but the system feels fragile and nobody's sure where the real risks are
Decisions happen quickly, but there's no clear end state for architecture or data model
You're adding features faster than you can reduce risk, and tech debt is becoming unpredictable
You need stronger review on big changes (migrations, boundaries, reliability, billing/data)
Fundraising or enterprise conversations are coming, and you want your technical story to be defensible

How it works

Technical Risk Audit

A focused deep dive into your stack, architecture, infrastructure, and technical debt.

Deliverable: a short written memo with what's solid vs fragile, the top risks, and a prioritized 90-day roadmap (what to do first, second, third).

$3,500–$5,000 depending on scope.

Retained Technical Oversight

Ongoing Staff-level review so decisions stay coherent as you move fast: design/code review, migrations, reliability, incident readiness, and technical decision-making.

$2,500–$4,000/mo depending on complexity.

What you get out of this

Clear direction: what to build, what to postpone, what to fix first
Fewer surprises: safer deploys, cleaner migrations, fewer fire drills
Decisions documented and repeatable—not trapped in Slack
A technical foundation that supports hiring, fundraising, and growth
