Six English-language courses built on the jonnify design system: functional programming on the BEAM, an agile workflow for shipping reliable software with Claude agents, the Redis design patterns taught applied, the EchoMQ job-queue protocol in depth, and the Branded Component System — identity as a contract, and Echo Persistence — durable state taught as built. Each is a deep, hands-on dive with interactive elements.
All six are taught in English and open in any order. Filter by track below.
A deep dive into functional programming with Elixir on the BEAM — from foundational to advanced computer-science problems, with interactive elements.
The Redis design patterns taught applied — each grounded in how a real polyglot job queue (EchoMQ) and the Portal platform actually use it. The catalog mapped, every pattern shown in real code.
The polyglot job-queue protocol behind the Redis course, taught in depth and tracked as it is built — the as-built core, then the extension ladder, grounded in real Elixir, Lua, and Go. The far side of every redis-patterns door.
Pragmatic Programming with Claude Agents — decompose into user stories, plan a roadmap, write the spec and agent brief, and prove each increment correct, built end to end on the Portal.
Boundaries are drawn around systems, and only identities cross them — identity as a contract. The 14-byte branded snowflake: typed, ordered, placed, canonical, proven by frozen transcripts across five runtimes.
The durable floor beneath EchoMQ — an in-heap accept tier, a transactional page-store built twice (Elixir on CubDB, Rust on Fjall), and replication to Tigris. Taught as built, bottom-up, each module an interactive dive into a mechanism.
