Real systems we built and run — the network, the tooling, the shops and platforms — with the decisions and the numbers behind them.
E-commerce
How we took letcon.ro — our own online store for development boards, sensors, soldering equipment and 3D printing — from an empty catalogue to a live, indexed, selling shop in one week, and what we built into it so it keeps earning search traffic.
Network Engineering
Our own ASN, our own address space, three independent transit providers — designed and operated without a NOC team, and verifiable by anyone on bgp.tools.
Security
We replaced a fake attack map with a real pipeline: IDS detections from the AS210622 edge, shipped over an authenticated fail-closed path, stored in SQLite, and rendered live — with a 'Blocked: 0' stat we refuse to inflate.
Platform Engineering
The runtime behind our invoicing platform — an API gateway, split public and admin APIs, four dedicated integration workers, and a simulator for the government API we cannot hammer in development.
Operations
Running community infrastructure on the fediverse: a full Rails stack, three separate Sidekiq tiers, pooled Postgres connections, and a monthly upgrade discipline — on a deliberately modest footprint.
AI-Driven Development
nftably, birdy, and meerkat — a firewall UI, a BGP control plane, and an IDS console — shipped in about four months with agents doing most of the typing and humans owning every design and merge decision.
