One person, two disciplines. I keep ledgers accurate and VAT returns filed on time for UK businesses — and I build the websites and internal tools that small businesses run on across the UK, Spain and Bolivia.
What I do
Most of my work is for owner-managed businesses too small for a finance team and too particular for an off-the-shelf website.
End-to-end record keeping for a business that needs its numbers to be right, not just present. Primarily Xero, with Hubdoc for document capture.
Websites and internal tools built to be maintained, not just launched. I work end to end — data model, interface, deployment, handover.
Selected work
Happy to walk through any of these in detail on a call.
A full site with a five-step reservation flow the restaurant owns outright, instead of paying commission per cover to a booking platform. Built plainly enough that the team can edit a menu without calling a developer.
The site for a station with a very large social following and comparatively little audience of its own. Server-rendered so it can actually be found, with the live player and schedule kept current alongside the station's internal teams.
A community futsal league running across London venues, with team and player registration, league tables, results and fixtures. Six years of continuous work on one codebase, built so a volunteer can update a matchweek by editing data rather than risking a deployment.
Sole charge of the books for a hospitality business: daily takings through to VAT return preparation, tips handled properly through a liability account rather than buried in revenue, and card settlements reconciled against POS reports so the two never quietly drift apart.

About
I'm Geischglin Rojas. I hold a first-class degree in Accounting and Financial Management from the University of Northampton and run the finance function for a UK restaurant; my first degree is in Computer Science, from the Universidad Politécnica de Madrid. For now the finance work is bookkeeping rather than accountancy practice: I don't prepare statutory accounts or tax returns.
The combination pays off in both directions. Knowing what a card settlement actually is means I can build a system that takes payments without quietly corrupting the VAT position behind it; having built systems means I can look at a bookkeeping process and see which parts are load-bearing. I'm based in London, with clients across the UK, Spain and Bolivia, in English and Spanish.
