About
Software engineer, 8 years across web, XR and mobile. Most recently built and shipped an enterprise mixed-reality product used by 100+ companies across four platforms. Sometimes as the only engineer, sometimes in a team of four with code review and sprint planning.
I also hand products over: onboarding developers, writing the technical docs, walking people through the architecture. The Kartoteka product line is now being sunset — the technology shipped and worked, the business case didn't.

Kartoteka
Software Engineer — XR & Web Platform
- —Built an enterprise MR product for interior renovation: the client walks their unfinished flat in a headset or on a phone and swaps real manufacturers' tile, brick and furniture in place. Adopted by 100+ companies since launch, ~40 with full product catalogues on the platform: models, textures and materials. Showcased at five industry expos and covered on national TV
- —Owned distribution across four stores: Meta Horizon, PICO XR, App Store, Google Play — store accounts, review submissions, release notes, update posts
- —Three Unity projects (MR, XR, AR) on Meta Quest 3, PICO 4 Ultra, iOS and Android, sharing a synced core and plugin layer. Platform differences go through compile-time defines
- —Cross-device multiplayer on Unity Netcode (host-client, RPC state sync), with a custom co-location method aligning a Quest and an iPhone to the same physical room, plus late-join scene replay. Validated across ~10 concurrent devices
- —Built the 3D asset pipeline behind 300+ production models: multi-pass decimation, retopology, normal-map baking, external texture compression. 500k-poly source down to ~5k, prep from ~4 h to ~30 min per model
- —Automated the release pipeline (Windows → macOS → iOS). Build time down ~60%, no manual config left
