I have connected online stores to Visma Nova, a POS system to a store, and bank statements to bookkeeping. The principle is the same everywhere: every row carries an external id, every run can be repeated, and every error leaves a trace.
Three integrations that move data every day without manual work.
Facade-panel store integrated with the Visma Nova / Loocos ERP
End-to-end bookkeeping automation for a sole trader, a limited company and a personal account.
Online store with 8,000+ products and continuous POS synchronisation
In integration work the first week goes into mapping and one working direction: where the data comes from, where it goes and how errors show up.
In a few lines: the project, the technologies, the timeline. I answer the same working day with my CV and the two closest examples of my work.
I start with a small, clearly bounded task in your repository and your tools. At the end of the week you see the code and decide what happens next.
Hours go into your tracker, the invoice comes from GG Solutions Oy. No lock in: we continue for as long as it is useful to you.
A company: GG Solutions Oy, Finnish Business ID 3465139-7. I invoice hours or an agreed scope. I am not looking for employment.
Java, .NET, native mobile and PLC programming. The core is Python, PHP and Laravel, React and TypeScript, PostgreSQL and MySQL, Docker and AI integrations.
Yes. Many end clients want their own interview and a CV with references, and both are fine.
The first week is a bounded task. If the result does not convince you, we stop there and you pay only for the hours worked.
Central and Northern European working hours are covered. I work remotely, or hybrid from Helsinki.
Send the systems, the API documentation if there is any, and the timeline. I answer the same working day.
