Work
Things TFKS builds and runs. Each one exists because a real problem needed solving; together they show the kinds of systems I can build for you.
Products
PimStash
A growing collection of practical apps for organizing the things people own and manage: gear, bills, vehicles, receipts. Designed, built, and operated by TFKS.
WebBits
Small, single-purpose browser tools that run entirely in your tab. No account, no server, no build step.
Engineering
LogBus
A streaming event processor for composing pipelines from pluggable sources, transforms, and sinks. Built for predictable behavior at capacity: 25+ sources, sinks, and codecs; 67,500 events/s sustained through seven stages with a JavaScript transform in the hot path; zero drops across 35.4 million events. One static binary.
Relevant to: event pipelines, observability, log processing. Docs 路 Writing
FJX
An agent-accelerated forge where humans and LLM agents collaborate on software through the same issues, pull requests, and labels. Scoped agent roles, swappable model adapters, and every run containerized with a full transcript.
Relevant to: agentic workflows, developer tooling. Docs 路 Writing
DropBear
Self-hosted file sync that pairs local folders with any S3-compatible bucket. Content-addressed storage, with a daemon, web dashboard, menu-bar app, and Android client.
Relevant to: storage, sync, multi-client apps. Docs 路 Source 路 Android App
Trippin
A travel log built around trips, points of interest, and photos, with a map-first browsing surface. Agent-coded successor to FotoLog, with vision models and embeddings doing the photo auto-curation. Fresh (Deno) and Preact on Supabase.
Relevant to: full-stack web apps, AI-assisted curation, agentic development. trippin.tfks.net 路 Source
GameOn
An Android app that hosts browser-based multiplayer games with no Internet required. One phone runs a Wi-Fi hotspot, an embedded HTTP server, and an authoritative WebSocket game server; players join by scanning a QR code. No install, no login, no account.
Relevant to: offline-first systems, mobile, real-time multiplayer. Source 路 Android App
