Senior software engineer. Ten-plus years building and running production systems end to end: cloud infrastructure, backend services, data pipelines, and native apps. I like small tools that remove a problem you had stopped noticing.
- Core AI and deep-tech products: real-time voice agents on self-hosted inference (LLM serving, speech-to-text, text-to-speech, telephony), retrieval and analytics over large public datasets, and drug-discovery research tooling.
- Payments and fintech infrastructure: self-hosted fiat and multi-chain crypto on-ramp/off-ramp, payment orchestration, and ledgering.
- Commerce platforms: headless storefronts, B2B marketplaces, pricing and analytics engines over multi-million-row export datasets, and the ETL behind them.
- Native mobile and desktop: Swift/SwiftUI on macOS and iOS, Kotlin on Android.
- Infrastructure and operations: AWS and GCP, Docker, Kubernetes, self-hosted PaaS, CI/CD, observability, cost control.
- Security: penetration testing background, GDPR audits, hardening of the systems above.
Small, single-purpose utilities for problems developers live with by habit. Each one is open source, read-only unless you tell it otherwise, and ships as a native macOS app plus a command-line tool where that makes sense.
- Prune: finds and safely removes regenerable developer artifacts and caches: node_modules, Rust target, Xcode DerivedData, Homebrew, pnpm, Go and 40 more. Trash by default.
- Stale: finds the git work on your Mac that exists nowhere else: uncommitted changes, unpushed commits, branches with no upstream, stashes, repos with no remote.
- Shadow: shows which node, python, ruby, java and go actually run in each shell, every shadowed copy, and the rc-file line that made the winner win.
- Histclean: finds API keys, tokens and passwords sitting in your shell history and redacts them in place. Offline, never touches the network.
- Wake: explains what woke your Mac, what is blocking sleep right now, which settings drain the battery, and battery health, in plain English.
- truestats: a GitHub Action that renders profile stat cards from the GraphQL API with your own token, so private contributions count and nothing depends on a third-party server. The cards below come from it.
- janitor: audits every repository you own for missing descriptions, licenses and topics, stale forks and archive candidates, and fixes the safe ones. Dry run first, always.
Recent upstream work includes CI improvements in kubernetes/minikube and a diagram-rendering fix in mermaid-js/mermaid.

I taught astronomy and space science, led a sales team, and ran my own digital marketing and development agency. That mix is why I care about tools people can actually adopt, not only tools that are technically right.
