Career break dedicated to full-time parenting while building Snapper — a single-builder, AI-assisted trading and market-data platform with multi-operator workflows. The platform handles crypto and commodity market data, paper execution, live-execution adapters, and multi-strategy backtesting on a single bitemporal data model. Cross-asset risk framework applied uniformly across BTC perpetuals, WTI futures, and Gold. Public OSS components published under MIT (snapper-mcp, snapper-frontend, snapper-ios); backend remains private. Alongside Snapper, built three fully open-source projects — hestia (cloud-free smart-home server via a clean-room reimplementation of Keemple's cleartext 0x7e binary protocol; Python/aiohttp + SQLite, RTL-SDR 433 MHz feeder, 46-language dashboard, 100% test coverage; AGPL-3.0), Vesta (native SwiftUI iOS client for hestia with API types generated from its OpenAPI contract, live SSE updates and 45 languages with full RTL; ~100% unit-tested; Apache-2.0), and rdsclock (pure-Python passive RDS Clock-Time receiver that recovers UTC from FM radio when GPS/NTP are unavailable; Apache-2.0).
Key Achievements
- Built Snapper — a single-builder, AI-assisted trading and market-data platform with bitemporal data model; multi-strategy cross-asset backtests on BTC perpetuals, WTI futures, and Gold under one risk framework.
- 100% test coverage on the core backend: 2,392 unit + 12 e2e tests; ZeroMQ pub/sub runtime; production-grade observability (process metrics, DB stats, retention scheduler, notification sidecar).
- Multi-model AI delegate review system over MCP — orchestrates Claude / GPT / Gemini / Copilot reviewers across the codebase.
- Published 3 OSS components under MIT: snapper-mcp (TypeScript / npm), snapper-frontend (React 19 + Vite, v1.3.1), snapper-ios (Swift, v0.1.3); backend remains private.
- Built hestia — cloud-free local control for Keemple smart-home devices via a clean-room reimplementation of their cleartext 0x7e binary protocol; transparent-proxy and cloud-replacement modes. Python/aiohttp + SQLite, 433 MHz RTL-SDR sensor ingest, TypeScript/Vite dashboard in 46 languages, 100% test coverage. (AGPL-3.0; v1.2.0)
- Built Vesta — SwiftUI iOS client for hestia, with API types generated from its OpenAPI contract; live SSE updates with auto-reconnect, multi-gang control, 45 languages with full RTL. ~100% unit-tested. (Apache-2.0; v1.0.0)
- Built rdsclock — pure-Python passive RDS Clock-Time receiver that recovers UTC from FM broadcasts when GPS/NTP are unavailable, using multi-station consensus. (Apache-2.0)
