I came to open source from a hands-on engineering background rather than a traditional software career.

I started exploring Linux more seriously after getting tired of the limitations and friction of my previous desktop environment. I became an active user of CachyOS and other open-source tools, and eventually realized that I could do more than just use other people's work — I could contribute useful fixes back upstream.

I enjoy practical, verifiable problems: reproduce the issue, find the root cause, make the smallest useful fix, validate it locally, and send it upstream.

My main areas of interest are Linux, developer tooling, CLI and backend systems, debugging, regression analysis, CI, and reproducible fixes.

A curated selection of verified upstream contributions:

• open-coder-ai/chock#38 — Added an Antigravity CLI governance adapter with mirrored templates and validation coverage (TypeScript).
• shakenfist/shakenfist#3805 — Fixed single-element tuple syntax in state targets for instance deletion lifecycle (Python).
• vooyajs/vooya#51, #40, #39 — Diagnosed mutable borrowed string ABI types, enforced public ABI boundaries, and preserved comments inside contract defaults (Rust / WASM).
• McanKul/offpdf#45 — Hardened AppError type guard against malformed runtime values (TypeScript).
• kpavlov/kt-schema#114 — Added BigInteger and BigDecimal numeric type support to schema generator (Kotlin).
• optiland/optiland#734 — Added geometric overlap diagnostics for optical lens surface visualizations (Python / PyTorch).
• vinhnguyenthanhdn/claude-jobs#7 — Preserved unrelated crontab entries and formatting during CLI uninstall (Node.js).
• Ramzi-Abidi/filebouncer#42 — Ensured --json output remains strictly serializable on error conditions (TypeScript / Node.js).

• CachyOS/ananicy-rules#597 — Keep ly-dm session launcher out of SCHED_IDLE scheduler policy to prevent child session priority inheritance (Linux / scheduler).
• CachyOS/cachyos-fish-config#41 — Forward history management subcommands cleanly without invalid timestamp flags (Fish Shell).
• OpenEverest/openeverest#2949 — Set explicit read and idle timeouts on plain and TLS HTTP listeners (Go / HTTP).
• apache/fesod#1020 — Added java.time.ZonedDateTime converters with focused conversion, formatting, and windowing tests (Java).
• CachyOS/CachyOS-Settings#255 — Redact enumerated machine values from bug reports with shell-level regression coverage (Linux / privacy).

• fb2-silero-audiobook — Offline Russian FB2-to-MP3 audiobook generator for Linux with Silero TTS v5.5, CPU/CUDA inference, custom pronunciation dictionary, structured JSONL logging, and fast FFmpeg chapter assembly.

Open source comes first for me, especially improving software I actually use.

If something I contributed helped you, saved you time, or solved a real problem, support and coffee are always appreciated.

Useful first. Support optional.
