Backend, Data & Infra
This is not a proxy in front of something — the Nginx setup runs in production on antonpetnitsky.com: one hybrid vhost serving the static portfolio, the research catalog and the Botka Mini App, with guard-tested config in
Mukller/antonpetnitsky.com. Services are wired via systemd units, reverse-proxied and reached over Tailscale.
Embedded & Robotics
LiDAR (RPLIDAR LDS-01) on a 3-wheel omnidirectional platform, plus Klipper/Fly-D7 3D-printer control on a Raspberry Pi Zero 2 W.
Mobile & Client Work
Delivery platform «Safalife» — private, built on commission. A water-delivery business ordering stack: a Flutter courier app (signed Android releases, build pipeline) plus two Telegram bots in Russian and Uzbek for clients and couriers, backed by a FastAPI service and PostgreSQL. The code is closed and not published — it belongs to the client — so what is described here is architecture and scope, not source. Handling a real client's release process, versioning and signing from end to end is the part worth noting.
