GIA Spatial Reasoning Practice
RotateMirror
Built for the parts people don’t see.
Two practical GIA spatial reasoning tools, built from the same production-minded approach.
01Thomas GIA Spatial Reasoning SimulatorA timed simulator for the Thomas GIA spatial visualisation test. It generates rotated and mirrored letter pairs, tracks accuracy and speed, then reviews every answer.
02GIA Spatial Reasoning PracticeLearn why rotation is allowed but mirroring is not, then practise at your own pace.
From the first page to the system behind it.
Websites, integrations and custom software, from first design through production. The useful work often starts where the website ends.
Websites that work
Fast, accessible and search-friendly websites and landing pages for small businesses, non-profits and professionals. Built so you can update them yourself, hosted cheaply, and without bloated page builders.
Integrations & automation
Connect the tools you already pay for. Payments, CRMs, ERPs, accounting, email and spreadsheets talking through APIs and webhooks, so data stops being copied by hand.
Custom web apps & SaaS
Booking systems, client portals, internal dashboards and multi-tenant SaaS backends. Designed for the long run: tested, documented and easy for the next developer to pick up.
Cloud, DevOps & rescue
AWS infrastructure as code, CI/CD pipelines, cost reviews and production support. I can stabilise inherited PHP applications and modernise them step by step.
A clear route from problem to production.
Clear scope, a fixed quote and frequent demos. No surprises, and you can see progress every week.
- 01 / Understand
Sniff
A free call to understand the problem, the users and the budget. You get an honest opinion, even if the answer is “you don’t need custom software”.
- 02 / Define
Plan
A short written proposal: what gets built, what doesn’t, timeline and a fixed price. Bigger projects are split into milestones.
- 03 / Make
Build
Weekly demos on a live preview link. Automated tests and reviewable code from day one, so quality doesn’t depend on luck.
- 04 / Run
Fetch
Launch, hand-over and documentation. Optional monthly care plan for updates, monitoring and small improvements.
One engineer.
One excellent supervisor.
Pyxel is a one-person studio run by a back-end engineer with 15+ years building and running SaaS platforms. I work remotely from Europe with clients worldwide.

Good questions.
How long does a project take?
A small business website usually takes two to four weeks. Integrations and custom apps depend on scope; after the first call you get a timeline split into milestones, each with something you can see and test.
Can you work on an existing codebase?
Yes, and it is a large part of the work. Taking over legacy PHP applications, upgrading frameworks, adding tests and fixing production issues without rewriting everything at once.
What does hosting cost after launch?
For most websites, close to nothing: static hosting on a global CDN is free or a few euros a month. Apps with servers and databases are sized to their real traffic, and you always own the accounts.
Do you offer support after launch?
Yes. An optional monthly care plan covers updates, security patches, uptime monitoring and a few hours of small improvements. No lock-in; you can take the code anywhere.
