I like figuring out why things break, mostly around Windows, and networks, and fixing them. I direct and test small, focused tools built to solve one specific annoying problem, using AI to help with implementation.
- Cloud fundamentals: what's actually happening under the abstractions
- Systems internals: how Linux, processes, and networks behave
- Networking and Windows troubleshooting: the stuff that comes up in IT/support work
- Fortinet NSE 1, enough security to understand the surface, not the whole field
- Small tools built out of curiosity, each solving one specific problem
- Repos that exist to work, not to look polished
- Notes left behind so future-me doesn't have to figure it out twice
Main projects
- formseal: server-blind encrypted form submissions. A browser embed encrypts with X25519, a CLI fetches the ciphertexts, and an offline CLI decrypts them locally. No hosted service, no backend trust.
- Libreprobe: self-hosted connection stability test. It probes 6 endpoints and reports latency against baseline bands.
- TinyScripts: my org for small portable Windows tools, each a single .exe built with the compiler that ships with Windows.
Also
- hyperos3-debloat: ADB debloat lists for Xiaomi HyperOS 3 (fork, tested on one phone)
- Personal site and blog: ggva.pages.dev
An IT / technical support internship or entry-level role. Troubleshooting, systems, and networking over writing code from scratch.
