## Work

- [Workers IO (YC F26)](https://workers.io/): Developer Relations Engineer, Sep 2026 – Present. Leading developer relations at Workers IO, a YC F26 startup. A founder reached out after seeing Breakscale, and the offer came 10 days after the repo went up. I never applied.
- [Vercel OSS Program × Breakscale](https://breakscale.tech): Founder & Maintainer, Aug 2026 – Present. Selected for Vercel's Summer 2026 Open Source Program in September 2026, which backs Breakscale for the next 12 months.
- [Google Summer of Code 2026 · KDE Kdenlive](https://invent.kde.org/multimedia/kdenlive/-/merge_requests/887): Open Source Contributor (C++ / Qt), May 2026 – Sep 2026. Selected among ~1,200 contributors worldwide for a 350-hour Large Project, and shipped all three of it: a per-channel RGB curve editor with tabs, a 32-stop gradient map editor, and a speed ramp UI built on Kdenlive's keyframe types. All merged into master and released in Kdenlive 26.08, written in C++ and Qt under maintainer Jean-Baptiste Mardelle.
- [Open Source](https://github.com/nlohmann/json/pull/5332): Contributor, 2025 – Present. 72 merged pull requests into repositories I don't own, across nuxt/nuxt, kubernetes-sigs/headlamp, nlohmann/json, vitest, croc, Zeal and OneUptime, plus 20+ upstream contributions to KDE Kdenlive and MLT through GSoC 2026.

## Projects

- [HatchZip](https://hatchzip.dev): Extract huge archives in place. It unpacks from the end and cuts the archive shorter as it goes, so a 180 GB download that unpacks to 200 GB needs a little over 200 GB free instead of 380. Crash-safe and resumable, tested by killing it at every commit point. ZIP, 7z, tar, RAR and split archives, as a CLI and a native desktop app.
- [Breakscale](https://breakscale.tech): Build a system, load it until it breaks, and watch why. A system design simulator with a real discrete-event engine: 33 components, measured percentiles, retry storms that collapse on their own. 1,000+ GitHub stars in its first week, part of Vercel's Open Source Program and sponsored by Workers IO.
- [Gyotaku](https://gyotaku.app): Search every screenshot you've ever taken by the text inside it. Native on Linux, macOS and Windows, fully offline: PaddleOCR, SQLite and GPUI, with 1-10ms search across 5,000+ screenshots.
- [mytimetheirtime](https://mytimetheirtime.com): Share your free time in someone else's time zone. Drag on a 24-hour clock, and a second clock shows the same hours in their zone. Send it as a short link that opens in the reader's own time zone, with no sign-up and no database: the whole schedule is packed into a link of about 23 characters.
- [Kdenlive (GSoC '26)](https://kdenlive.org/): GSoC 2026 contributor for Kdenlive, the open source video editor. Three effect widgets in the C++/Qt codebase, all merged and shipping in Kdenlive 26.08: per-channel Curves, a multi-stop gradient editor, and keyframe types for time remapping.
- [Photon](https://xevrion.dev/blogs/photon-blog): A nanosecond-scale NASDAQ ITCH 5.0 feed handler and matching engine in C++20, with zero-copy parsing, a lock-free SPSC ring, busy-polled UDP multicast, and per-symbol order books. 38ns median parse on real market data, measured over loopback.
- [Flock](https://flock-demo-canvas.vercel.app): An embeddable real-time presence and multiplayer-cursor SDK. Drop it in and see who else is on the page, with live cursors and awareness, in a few lines of code.
- [cutback](https://github.com/xevrion/cutback): Version control for Kdenlive projects. Watches a project folder, commits every save to a local git repo without being asked, and describes what changed in plain English instead of a diff of MLT XML.
- [Grindmap](https://grindmap.xevrion.dev): The LeetCode questions companies actually ask, ranked by frequency, as a static site generated straight from CSV data.
