## Writing

- [The summer I mistook capacity for focus](https://gsubils.com/writing/doing-everything-at-once) (2026-10-10, craft): In the summer of 2026, I launched Balance while building for JGS Store, working on Faktu and taking on freelance clients. Almost everything moved forward. That was part of the problem.

## Projects

- [JGS Store](https://gsubils.com/projects/jgs-store): Premium FiveM scripts built with Lua and Vue: chat, HUDs, pause menus and a custom storefront.
- [Faktu](https://gsubils.com/projects/faktu): An invoicing platform that helps companies and self-employed professionals manage their work and prepare for VeriFactu.
- [Balance](https://gsubils.com/projects/balance-ios): An iOS app connected to Apple Pay that records every expense automatically and keeps all data on-device.
