Gateway.fm
Institutional onchain infrastructure
Where I work, as co-founder and CTPO — infrastructure for institutions moving finance onchain: RPC, rollups, indexing, interoperability, and privacy. My work there spans Gateway Platform, Presto (Blockchain-as-a-Service), and rollup engineering (cdk-erigon, aggkit-proxy, cdk-validium).
Open Privacy Suite
Privacy layer for institutional EVM
The product I currently spend most of my time on: an open, vendor-lock-in-free privacy layer for public and private EVM networks. A JSON-RPC privacy proxy with role-based access control, selective disclosure, compliance tooling, audit trails, and a privacy-aware explorer — organizations control who can see what, prove what happened, and meet real operational and regulatory requirements.
LE FLAC (LF-1)
Android · Kotlin
A local-first FLAC player for Android / Nothing Phone: no network permission, no accounts, no telemetry. Behaves like a piece of field equipment — it analyses every track, keeps a clock on the sleep screen, and runs an LED cassette deck on the Glyph Matrix.
Most software is built outside-in — features wearing a skin. This unit was built inside-out. The skin is the feature set.
RFF — Request of Funds
macOS · Swift
A macOS menu bar app that runs the whole money-paperwork loop for a small consultancy: bills caught, classified by on-device AI, tracked until paid; invoices generated; accountant report one click away. Absorbed the former invoice-monitor app.
Interfast
Android · Kotlin
The intermittent-fasting app that doesn't track you: a private local scheduler instead of a tracker. “Closer to a kitchen timer than a wellness app.”
Fasting doesn’t need streaks, charts, or badges. The only hard part is knowing when each biological milestone hits.
Erigon
Ethereum execution client · Go
Ethereum implementation on the efficiency frontier (formerly Turbo-Geth). One of the founding engineers (not active on it now). Chapter: state tries, witnesses, sync, RPC infrastructure.
Stateless Ethereum research
Data & experiments · Python/Go
Done as part of Ethereum Foundation research. Public datasets and scripts from the stateless-era experiments: kv-witness data, resolver witness stats, binary tries data, binary tree hashes, and eth-bench transaction benchmarks.
AlfredSwitchWindows
macOS · Swift
An application for use in Alfred workflows to enumerate and switch between windows on macOS.
Timepiece for Mac
macOS utility
An elegant, minimalistic and free timer for productivity — pomodoro-friendly, fully keyboard-controllable. Still my daily timer; planning to open-source it.
