Freelancer profile translated to English.

Description

My name is Thomas. Python developer for 5 years, I design custom business software for SMEs: inventory management, scheduling, invoicing, customer tracking.

Are you wasting time with Excel or unsuitable tools? I develop simple and fast desktop applications, installed directly on your computer — no monthly subscription, no internet dependency, software you truly own.

I have worked on desktop interfaces (Qt/PySide), robust backends (Django), REST APIs, as well as plugins for third-party software. This versatility allows me to adapt to your existing tools rather than imposing a generic solution.

I can help you to:

•Create custom management software (inventory, customers, schedules, quotes/invoices)

•Migrate an Excel or paper system to real software

•Add features to existing software

•Ensure maintenance and evolution over time

Clear specifications before starting, regular communication during development, delivery of ready-to-use software.
