Streaming & CDN engine
Just-in-time HLS/DASH packaging from a single source, server-side ad insertion, DRM, multi-tier edge caching and load balancing. Engineered toward 100 Gbit/s per node, with origin shielding and weighted edge routing.
// Projects
An in-house platform, and the open-source tools around it. Code efficiency matters.
The Platform
A coherent infrastructure stack written from scratch in C and evolved since 2014. One shared core — custom sharding, replication, automatic failover and live resharding over HTTP/2, HTTP/3/QUIC and mTLS — carries every product built on top of it. The components below are proprietary; the engineering is described here in the abstract.
Virtualization control plane
VM and container lifecycle, live migration, ZFS/Btrfs/LVM storage, BGP/EVPN networking, lease-based high availability and disaster recovery — a leaner alternative to heavyweight enterprise platforms, with sovereign peers over mTLS and HTTP/3.
Distributed object & data stores
Horizontally sharded storage with quorum replication, gossip-based automatic failover, live resharding and cross-region sync — including an S3-compatible gateway. Strong consistency where it matters; streaming of multi-gigabyte objects without buffering them in memory.
Fleet monitoring & telemetry
Lightweight push-based agents with crash-safe offline buffering, multi-collector redundancy and SNMP/JSON collection — built for fleets from IT estates to broadcast plants. Months of buffered data survive an outage and catch up in minutes.
Apps
Small things we built for ourselves and give away. Free, no ads, no tracking.
CELAJE – weather, clock & tide widget
A home-screen widget with the essentials at a glance and a full multi-day chart behind it: temperature, cloud and sunshine, rain, wind, pressure, tides, sun and moon, UV — plus a star map and an astronomical almanac. No account, no location permission; astronomy and the default tide model run on the device.

ft – Fearless Terminal
A fork of suckless st with tabs, split panes, Lua configuration and session logging. Uses Xft for font rendering — no OpenGL overhead, no GPU wake-ups for text. Single process, efficient, hackable.
# build
make clean && make
sudo make install
Just a small experiment.
