I build software, and keep it running.
WealthR, Mailfois and FormatTools: designed, built, launched and run by me, alongside a full-time job. This is where they live together, with the occasional build I take on for someone else.
One person · Everything here is live · Built in Edinburgh
Three products, built and running.
WealthR has real users, real payments and real support emails. Mailfois is live and looking for its first pilot teams. FormatTools strips personal information from text before it goes into AI, and has 23 other free data tools, all running in the browser.
WealthR
A UK wealth tracker and retirement planner that people open every month to see where their pensions, investments and property are heading. Free to use, with a paid Pro plan.
Mailfois
A workspace for email teams sending across markets and languages: campaign planning, a brand checker, review rounds with client sign-off, and a permanent archive.
FormatTools
Strips names, emails, NI numbers and bank details from text before it goes into ChatGPT, Claude or Copilot, then puts them back in the answer. Plus 23 other data tools. Everything runs in the browser, so nothing anyone pastes is uploaded.
A demo is the easy 20%. This is the rest.
Anyone can make a screen look good in a weekend. What makes software safe to put real customers and real money through is everything underneath, and it's the part I enjoy most.
Email and password, magic links, invites, and people only seeing what their role allows.
Row-level security on every table, so one customer can never see another's data, even through a bug.
Stripe checkout, plans, upgrades, failed payments and webhooks that don't double-charge.
Branded transactional email with SPF, DKIM and DMARC set up, so it lands in the inbox and not spam.
Data export, deletion, privacy notices and knowing exactly where personal data lives.
Cloudflare's edge and a managed Postgres database, running for pennies until you're big.

Occasionally, I build for others.
One build at a time, when the problem's a good fit. Fixed price agreed first, and you own the code. These are the three ways in.
Finish an app built with AI
A fixed-price review of an app built with Lovable, Bolt, Replit or Claude: a written list of what's wrong, ranked by risk, and a fixed price to fix it. Taken off the fix if you go ahead. Or run the free launch checklist yourself first.
Turn an idea into a plan
For founders with an idea but no developer: a written plan for the first version, rough screens and a fixed build price. Taken off the build if you go ahead, and the plan is yours either way.
Build a tool or portal
A tool that replaces a spreadsheet, a client portal, or a quote or booking flow. Portals from £2,500 and first product versions from £4,000. Half to start, the rest at launch, with 30 days of fixes.
Hi, I'm Liam.
I'm an email marketer and a self-taught developer. I've worked in marketing for over 12 years, from B2B travel trade and social media to email, and today I work on automation projects for internal stakeholders and for consumers. The software grew out of that: I've been the person stuck with clunky tools, chasing sign-off over email and keeping a spreadsheet alive.
Today I build and run WealthR, a UK wealth planner with paying users and five-star reviews, Mailfois, a workflow tool for email teams, and FormatTools, free tools that strip personal information before it goes into AI.
I do all of this alongside my full-time marketing role, so client builds are occasional: one at a time, when it's a good fit. If we do work together, you deal with me from first call to handover, and the person who wrote the code is the one who fixes it.
“Not only was the application well designed and feature rich, Liam's support was exemplary.”

Before you get in touch.
Do you take on client builds?
Occasionally. I build alongside a full-time role and my own products, so I take on one build at a time, when the problem is a good fit. The easiest way to find out is to tell me what you need.
What does a build cost?
Every build gets a fixed price, agreed in writing before any work starts. As a guide, a tool or booking flow starts from £1,750, a client portal from £2,500 and the first version of a product from £4,000. You pay half to start and the rest at launch, and 30 days of fixes after launch are included.
I built my app with AI. Can you finish it?
Usually, yes. I start with a fixed-price review: I go through the code and the live set-up and give you a written list of what's wrong, ranked by risk, with a fixed price to fix it. The review costs £350, which comes off the fix if you go ahead. There's also a free launch checklist you can run yourself first.
I've got an idea but I'm not technical. Where do I start?
With a call. If software is the right answer, the next step is an idea-to-plan session: a written plan for the first version, rough screens and a fixed build price. It costs £495, which comes off the build if you go ahead, and you keep the plan either way.
Do I own the code?
Yes. The code lives in a repository you own, payment accounts are always in your name, and it's built on standard tools any competent developer could pick up.
Do you use AI?
I use AI tools to build faster, and I put the same checks on that work as on anything else. Inside the software, I only add AI where it earns its place. Mailfois uses it for optional image alt text, while its brand checker deliberately uses none, because every finding has to be a fact.
Say hello.
About one of the products, a build, or something else entirely. A few lines is plenty, and I reply personally, usually within a day or two.
Not sure it's worth building?
Ask anyway. Half of good scoping is working out what not to build. If an off-the-shelf product will do the job, I'll tell you which one, and it won't cost you anything.
No sales script, and I won't chase you afterwards.
