Technical strategy & architecture
Roadmaps, build-vs-buy calls, and architecture that fits your stage and budget — so today's decisions don't become tomorrow's rewrite.
Fractional CTO & Technical Leadership
Senior engineering leadership,
without the full-time hire.
MBX Technologies is the practice of Michael Butler — a hands-on CTO who helps founders and scaling teams set technical direction, ship product, and build engineering they can rely on. Strategy when you need a steady hand, and code when you need things shipped.
How I can help
Engaged fractionally — a few days a month or an intensive sprint — to give you the technical leadership a senior hire would bring, at the stage you actually need it.
Hands-on delivery
I still write production code. When a build needs to happen, I can lead it from the front rather than just advise from the side.
Team & engineering leadership
Hiring, mentoring, and the processes that turn a group of developers into a team that ships predictably.
Scaling & platform work
Taking products from prototype to dependable platform — performance, reliability, integrations, and the unglamorous foundations that matter.
Selected work
A mix of companies I've founded, led, and built for.
Insert Affiliate
A platform that lets app developers track affiliate-driven in-app purchases on iOS and Android, manage affiliates, and automate commission payouts.

SIFS & Open Access
The School of International Financial Services delivers digital and in-person education to financial services professionals worldwide. As fractional CTO I lead the technology — and single-handedly built Open Access, the platform serving 350+ hours of live webinars and CPD a year across compliance, governance, taxation and digital assets. Strategy and the keyboard, both.
About
I'm Michael Butler — a founder and engineer based in Jersey. I've been writing code since 2015 and working professionally since 2018, and in that time I've started my own product company, taken on the CTO role at a venture-backed marketplace, and acted as the fractional technical lead and sole developer for an international education business.
That range is the point. I've felt the pressure of being the person who has to make the call and ship the result. When I work with you, you get both: the perspective of someone who has run engineering, and the hands of someone who still builds.
MBX Technologies works with a small number of clients at a time, so the attention is genuine. If that sounds like what your team is missing, let's talk.
