Building practical systems from data structure to interface.

I build practical web applications and internal systems, working from data structure and system logic through to the interface. Each project is documented like a working drawing: the problem, the approach, how the system is put together, and what it delivers.

LAN Meeting App

Internal meetings needed a simple way to gather notes, participant lists, and discussion outcomes in a structured form. Separate documents made note-taking and merging results impractical, especially when several participants needed to contribute at the same time. LAN Meeting App is built to run entirely over the local network, so a meeting works over Wi-Fi, tethering, or an internal network without depending on an internet connection or an external cloud service.

Inventaris Vidatra

Inventory management previously relied on spreadsheets, so recording assets, numbering, item identification, labeling, and compiling reports still required manual work. Separate files also made inventory data harder to manage centrally. Inventaris Vidatra was built to turn that workflow into a web-based system with a centralized database, QR/barcode asset identification, and labeling and report export features.
