The software development company that is one senior developer.
Registered, invoicing, under contract — and when you buy a build, one person designs it, writes it, tests it and ships it.

Most firms setting out to hire a software company are trying to get one thing built properly. The usual route to that is a team you never meet, a discovery phase that bills by the day, and a codebase you inherit but cannot maintain.
This is the other route. Scope is fixed and priced once, before anything starts. The person you speak to is the person writing the code. What you get at the end is software that runs and a repository any developer can pick up.
// what gets built
Four shapes of work.
Narrow on purpose. If what you need is outside this, I will say so and point you at whose job it is.
01
Web applications
Accounts, permissions, payments, documents, file handling — the parts where getting it wrong is expensive rather than embarrassing. Built so the rules hold at the database, not only in the interface.
02
Internal tooling & automation
The repetitive work your team does by hand every week, removed. Usually this starts as an audit of where the hours actually go, which occasionally ends with me telling you the software is not the answer.
03
AI workflow engineering
Pipelines that do real work and are checked rather than trusted. The verification layer is the deliverable — anything can produce output, and output nobody validated is a liability with good grammar.
04
Full products, end to end
Architecture through to a thing in real hands: database, auth, billing, email, the interface, the deploy. One person carrying it means nothing falls between roles, because there are no roles.

// the honest comparison
What you are choosing between.
Not a pitch that every alternative is bad. A description of the trade you are making.
| The question | A development agency | Here |
|---|---|---|
| Who writes it? | A team assembled after signing, often more junior than the people who sold it. | the person you spoke to |
| What do you own? | A framework, a build pipeline and a dependency list somebody has to keep current. | plain code, no lock-in |
| How is it priced? | Day rates. The estimate grows with the discovery, and discovery is billable. | one fixed number |
| Who do you chase? | An account manager, who relays your question to someone else and the answer back. | nobody to relay |
| And the catch? | Capacity. An agency can put five people on it; a bus factor of one is a real risk. | one person, one queue |
The last row is the honest one. If your project genuinely needs five people in parallel, or a support rota, an agency is the right answer and I will tell you that on the call rather than after the contract.
What I turn down: anything needing round-the-clock cover or a formal SLA, staff augmentation where you want a body inside your team for six months, work that is mostly meetings, and rescue jobs on large codebases where nobody can tell me what the software is supposed to do. Those are real needs. They are not this.

Software I built and shipped myself.
Read this before the numbers. Everything in this section is my own product, built and funded by me on my own infrastructure — nobody commissioned it and nobody paid for it. It is here because it is the only honest way to show you what I can carry alone, at full size, with the awkward parts left in.
The paying client work on this site is Developer Genome and CityRoamer, and both are web builds rather than software engagements. I would rather you knew that from the first line of this section than worked it out from the badges.

// the method
Directed, not vibe-coded.
The fair question to ask anyone who ships this much on their own.
Every architectural call is mine, and so is every decision to reject one. I run an orchestrated build pipeline against those calls and sit in the middle red-teaming the plans and running the verification myself. The judgment and the refusal are the scarce parts.
Which raises the obvious objection: why hire me rather than the same tools? Because this is what those tools produce with nothing checking them — a privilege column that looks completely plausible and is writable from the browser; a payment status that flips on a redirect instead of a verified webhook; a storage rule that holds in the interface and not against a direct API call. Each one reads fine in review and fails the moment somebody hostile looks at it.
// working together
Where I work, and how.
Riga-based and remote. Riga runs two hours ahead of London and one ahead of Amsterdam, Berlin and Zurich, so the working day overlaps in full either way — you are not waiting overnight for an answer.
- Remote across the EU and UK, in English. Video calls, written decisions, and a reply within one business day.
- Fixed scope, one number. Agreed before anything starts. No hourly meter and no invoice that grows while you watch.
- You see it as it is built. Real software you can click, not status meetings and a demo at the end.
- It ships with a handover walkthrough. What was built, what changed and why, and the exact path to live — see a real one.
Tell me what the software has to do. I will tell you whether it is a job for one person.
Custom software, full products and AI workflow engineering are quoted case by case — the scope varies too much to shelf-price honestly, and they start well above the website offers. You still get one fixed number before anything begins. See the offers
