20 public projects, plus two games in development.
Seven research systems: a database engine, an XDR platform, distributed storage, an evidence engine, secure file delivery and a programming language, plus a Python workbench for connectome pharmacology. Then seven Apple-platform apps, two developer tools and six games, two of which are still in development. Each released project links to its source code, a demo or its release page.
Selected project work
Filter by category. The research systems link to a profile with scope, architecture and what the work does and does not show. The products link to their release page.
Start with these three
SkeinDB, a pre-1.0 database engine with a peer-reviewed paper and CI-measured replication results. Wardex, a released, self-hosted XDR platform (v1.1.0). MushBloom, an iOS app published on the App Store.
SkeinDB
A single-binary database engine with cell-interned MVCC, MySQL compatibility, partial PostgreSQL support, and twenty research tracks.
Paper · TechRxiv 2026
Wardex
A Rust-built XDR and SIEM platform for detections, fleet operations, incident response, and threat hunting.
Paper · Federated IDS, TechRxiv 2025
NexusFS
An offline-first distributed filesystem with signed operations, deterministic replication, and proof-ready storage semantics.
VeriLog
An edge-native evidence engine that turns device telemetry into tamper-evident logs with signed checkpoints.
SafeDrop
A home-hosted secure file drop with content-addressed storage, delivery receipts, and path-aware reachability evidence.
Patch
A change-oriented programming language and browser IDE with inferred contracts, provenance, and selected Lean-checked evidence.
FlyLab
A provenance-first pharmacology workbench on the Drosophila MaleCNS connectome that tests whether each prediction actually depends on the wiring.
ShotSift
Private photo decluttering for iPhone. Duplicates, screenshots and bursts are detected entirely on-device.
MushBloom
Mushroom cultivation companion with strain guides, grow journals, AI contamination scans and PDF export.
Rootling
Plant propagation tracker with rooting forecasts, visual journals, weather context, reminders and exportable records.
RidgeFocus
Pomodoro and deep-work timer with streak systems, widgets and lightweight productivity insights.
AppSweep
Universal macOS updater that unifies Sparkle, GitHub Releases and Mac App Store sources into one flow.
Focusledger Pro
Private macOS productivity tracker with local focus tools plus automatic timelines and analytics in Pro.
DiskLoom
Native macOS drive-health monitoring with local history, trend analysis and transparent compatibility reporting.
Violinen-Stimmer
German-language violin tuner with A=442 Hz, pure-fifth checks, reference tones and on-device microphone analysis.
Revolut Trade Scanner
Local trading scanner with out-of-sample-gated recommendations, risk sizing, live TP/SL tracking and an HTML dashboard.
Shelter Fall
Post-apocalyptic survival strategy with progression systems, dynamic events and escalating pressure.
Nomad Kitchen Tycoon
Food truck management sim with rush gameplay, rival trucks, loyalty rewards and truck financing across two cities.
Lancet Linen
Medieval barber-surgeon life sim: care, trade, travel, household, staff and civic ambition in 1382.
Ringjahr
A quiet puzzle about tree rings: place climate cards on a timeline, cut the trunk and match the target cross-section. 78 levels and a daily puzzle.
Germ Theory
A hospital management sim set in Hamburg, 1875–1892. Build wards, hire staff and push germ theory past a profession that still believes in miasma, up to the cholera of 1892.
Kontor
A strategy game about the invention of insurance, Hamburg 1590–1850. Price risk from letters, rumours and ship lists, and build the statistics yourself.
For technical readers
These profiles stay short. Three of the systems also have a longer technical write-up.
Architecture and implementation notes
The operator pages cover architecture and operating surfaces for SkeinDB, Wardex and NexusFS, with benchmark numbers only where they have been measured and published. The full operator view has the rest of the technical portfolio.
