I'm Mark Rawson, founder of Webhooks Ltd. Azure and .NET specialist, former Head of Engineering at Cardiff fintechs, based in South Wales a short drive from Cardiff. I build and ship product for UK founders.
I'm based in Tonyrefail, in the Rhondda Cynon Taf borough, a short drive from Cardiff city centre. Close enough for in-person scoping sessions, on-site workshops, or a coffee in Cardiff when a conversation needs to happen face to face. Day-to-day work is remote, so you're not paying for my time in the car.
A short drive from Cardiff, not a three-hour train from London. I can be at your office or a coffee in Cardiff in well under an hour. On-site when it matters, remote by default.
Over a decade of Azure and .NET in production, from Dynamics and Azure Functions in 2014 through to event-driven microservices on AKS today. Kubernetes in production since 2018, plus a personal k3s cluster I run for fun. Hard-won opinions, not reference architecture decks.
You work with me directly. No junior developer handed the brief, no project manager relay, no silent hand-off offshore. One senior engineer, directly responsible for what ships.
I work in productised engagements: a Paid Discovery, an MVP Sprint, a Feature Build or Rescue, or a Fractional CTO retainer. Clear scope, clear price, clear outcome. No open-ended day-rate drift.
Cardiff has a visible and growing tech ecosystem. A short orientation, in case you're earlier in the journey or based outside Wales.
Tramshed Tech in Grangetown is the best-known hub for Cardiff's startup scene. Welsh ICE in Caerphilly and the sbarc|spark building at Cardiff Innovation Campus round out the community. If you're looking for peers, events, or shared workspace, that's where to start.
The Development Bank of Wales provides seed and growth capital to companies across the region. Business Wales offers grant and advisory support backed by the Welsh Government. Together they're the first stop for most founders looking at non-dilutive or local capital.
Cardiff has a visible FinTech cluster anchored by FinTech Wales, a growing creative-tech scene around BBC Cymru Wales, and financial-services employers like Admiral and Principality that feed the local engineering talent market.
Six to ten weeks, fixed scope, milestone billing. For pre-seed and seed founders with funding (or a signed letter of intent) and a deadline. Built in .NET, Blazor, or React on Azure. Scoped honestly, shipped on time.
Technical leadership for non-technical founders: roadmap, architecture decisions, hiring, and Series A technical due diligence prep. One to three days per week on a three or six month retainer. From £2,500 per month.
Two to six weeks, fixed fee. For scale-ups with a stuck feature, a half-built product, or a deadline that needs senior engineering to land. Azure and .NET by default, happy to work in the stack you already have.
One to two weeks, fixed fee. A written recommendation on what to build, how long it'll take, and what it'll cost. For founders who aren't yet sure what they need. Often the cheapest way to de-risk the next six months.
Yes, when it helps. I'll come in for kickoffs, scoping workshops, board meetings, and technical due diligence sessions. Day-to-day delivery is remote so you're not paying for my travel time.
Happy to. If you're a Cardiff founder weighing up whether to build in-house, hire an agency, or bring in fractional help, I'll give you 45 minutes of honest advice over a coffee. No pitch deck. Book in via the contact form below.
No. I work with UK founders anywhere in the country, remotely by default. Being near Cardiff is a bonus for South Wales clients, not a limit on who I work with.
I know the names and broad positioning of the main players: the Development Bank of Wales, Cardiff Capital Region, FinTech Wales, and Business Wales. The deeper specifics of any one programme's technical expectations, I'll learn fast when you bring me in.
Tell me what you're building. I'll share honest feedback on feasibility, timeline, and cost. If I'm not the right fit, I'll tell you that too.
