Available for engagements

I build and fix software projects.

Signal Rate is James Pain. I work with founders and teams who need someone they can trust with the technical side of a web product or platform.

What I do

How I can help.

I become your technical co-founder

I step in as the accountable technical leader for a fixed term. I set direction, unblock delivery, and represent engineering to the board or founders, while you find, or decide whether you need, a permanent hire.

Interim & Fractional CTO

I tell you what's actually wrong, honestly

An independent, unsentimental review of your codebase, infrastructure, and team. You get a prioritised list of what's actually wrong, and the documentation your business needs if a key person leaves tomorrow.

Technical Audit & Continuity

I turn your idea into something real, however you want it built

You know what you want to build but not how. I turn that into a concrete plan (data model, system design, and a phased estimate), then take it as far as you need: build it myself, lead your existing team through it, or find and bring in the right people to deliver it.

Architecture & Scoping
Can I work with your stack?

Probably. This is what I've shipped with.

Languages & Frameworks
TypeScript JavaScript Python C# Visual Basic React Next.js HTML5 CSS
Databases
PostgreSQL Microsoft SQL Server MySQL SQLite Redis Supabase
Cloud & Infrastructure
AWS Google Cloud Microsoft Azure Power Platform Terraform Docker Linux
CI/CD & Observability
Git GitHub GitHub Actions TeamCity Jenkins Datadog Grafana Prometheus
AI & Machine Learning
OpenAI Anthropic / Claude Google Vertex AI AWS Bedrock YOLO / CLIP OpenCV FFmpeg
Platforms & Analytics
Chrome Extensions (MV3) Power BI WordPress

Not on this list? Most stacks share the same underlying decisions. Tell me what you're running and I'll tell you honestly if it's a fit.

Security & Compliance

Security isn't bolted on afterwards.

Most of the founders I work with are handling data they can't afford to get wrong: customer records, financial details, or personal information under GDPR. I design for that from the architecture stage, not as a retrofit once a client or regulator asks.

How it works

No deck, no pitch. Just three steps.

01

Intro call

It's free, informal, and takes about thirty minutes. You describe the situation, I ask questions, and we work out together whether it's actually worth taking further. Some conversations end here, and that's a fine outcome.

02

Proposal

If there's a fit, I write up what I found, what I'd actually do about it, and what it costs. No obligation. It's yours to take elsewhere if you'd rather use it as a brief for someone else.

03

Engagement

It's scoped from the start, so you know what "done" looks like. You work with me directly throughout, not an account manager or a delegate, with short regular updates instead of disappearing for weeks and reappearing with a reveal.

I'm happy to sign an NDA before the intro call if that's useful. Just say so when you get in touch. I keep my diary clear enough that a first call has, more than once, happened within an hour of someone reaching out.

Selected work

Built, launched, and scaled.

~20Years in software engineering
22Products taken from build to launch
80kDaily active users, on one of them
Writing

Occasional, unpolished, honest.

Get in touch

Got something worth a conversation?

Tell me what's going on: a team without direction, a system nobody trusts, or a build that needs a plan. I typically reply within a day.
