I'm Jonas, based in Rio de Janeiro, Brazil. I build desktop apps and organization systems for managing projects, records, and everyday tasks. My personal and academic projects cover business management, content workflows, and practical automation.
- Work organization: project boards, tasks, study libraries, and focus sessions.
- Business management: customer and product records, sales, and service orders.
- Content workflows: channel organization and separate local browser sessions.
- Automation and data: Python tools, database-backed apps, and Windows scripts.
| Project | Purpose |
|---|---|
| Editor Forge | Windows app for Kanban tasks, study material, and focus sessions. |
| TokFury | Windows app for organizing TikTok channels and browser sessions; in development. |
| InfoTechG | Java / MySQL coursework: store records, sales, repair orders, and menus by user role. |
| Auction system | Java / MySQL coursework for registering products and tracking sales. |
- SENAC — technical course projects: coursework organized by project, with activities, documentation and tests.
- My project catalog: grouped collections for coursework, work tools, web studies and references.
These collections are private and require access. Their links do not make the repositories public.
I also have a private desktop analysis project whose details are kept private.
