Ein gebildeter Geist ist fokussierte Seele; Kaffee kann nicht mithalten, Wissen spielt die Hauptrolle.
roughly: an educated mind is a focused soul, coffee can't keep up, knowledge plays the lead role. i drink tea anyway, so the coffee part was never a risk.
hi. i'm Jonas — jonaskahn on github, "just a 🍵" everywhere else.
i'm a self-described low-minded developer ٩◔̯◔۶ which is not modesty, it's calibration.
i write software, most of it open source, some of it even works. i live on 🌎 Earth-616 and run a guild of one
called IfelseDotOne (attendance: always 100%).
i started backend — Java, Kotlin, the Spring stack, the whole enterprise liturgy, i can still recite it from memory. frontend happens when nobody else will do it. these days the honest job description is i build AI systems and the plumbing around them — agents, RAG pipelines, orchestration, and the unglamorous infrastructure that keeps it all standing.
Years, Not Buzzwords
current focus: agents, RAG pipelines, orchestration — and the plumbing that keeps it all standing.
In Decreasing Order
of Confidence
Cadence
a multi-agent, multi-tenant AI orchestration platform. the big one. it has an SDK, an admin UI, docs, and example plugins, which means i accidentally built an ecosystem and now i have to maintain it.
AskTube
AI-powered YouTube summarizer & QA assistant using RAG. runs entirely on your machine with Ollama if you want it to. 86 kind strangers pressed ⭐ and i checked the count twice in disbelief.
unofficial-livecounts-api
live counts for TikTok/YouTube/Twitter/Twitch and friends. the word "unofficial" is doing a lot of legal work in that name.
EasyKey
a Vietnamese input switcher for macOS, written in Swift. Swift is my newest save file and i'm still in the tutorial zone, but the app scratches a real itch.
nomad-consul-vault-in-production
notes from actually running the HashiCorp stack in production. we survived. that's the review.
there are ~66 repos total. the rest are experiments, research, and things best left unindexed.
Five Things, Held Firmly
if it can run on my machine, it should. my AI tools work offline because my prompts are between me and my CPU.
search, infra, models. dependency on someone else's cloud is a subscription to someone else's decisions.
everything i can open, i open. it's the only economy where giving things away makes you richer.
one of my repos is literally described "simple app for simple life." that's the whole architecture review.
no launch threads, no countdown. push, exhale, tea.

The Quirks Ledger
No Circuit
no talks, no conference circuit. if i have longer thoughts they end up on the blog instead.
