About

Full-stack engineer, six years fully remote. I build the parts of a system where correctness is the product. Most recently that has meant provider-agnostic object storage — one interface, swappable S3/GCS/Azure backends, hand-rolled request signers with no cloud SDKs — so a platform hardwired to one vendor could be sold to regulated and on-prem customers. Before that, re-architecting who owns a value when two systems both think they do, which is how you stop a lost-update race for good instead of patching it. I also build AI systems with explicit safety boundaries: a multi-agent automation fleet whose executor tier is human-gated by construction, and a multimodal reviewer that reads visual diffs and reports what changed — advisory by design, never blocking. Automation earns trust by being structurally unable to do the dangerous thing, not by promising not to. I work written-first — ADRs, design docs, PR-level analysis — with reviewers across timezones. Toronto, Eastern Time, full overlap with US hours. Remote only.

Work Experience

Slice

July 2026 - Present

Senior Developer

Design system and web platform work across two consuming product apps.
  • Replaced the design system's i18n primitive after finding it could not express ICU plurals in translatable files — a limitation that would have blocked the translation pipeline for every component in the localization epic.
  • Shipped an ICU-native formatter hook with typed message keys, a session-shared parse cache, and per-component catalogs so consumers bundle only the strings they use; externalized in the Vite build at zero bundle cost to either app.
  • Raised the finding as a documented team decision rather than changing shared architecture inside a feature PR — labeled the analysis unverified pending a spike and escalated to owners of both consuming apps.

June 2020 - July 2026

Senior Full Stack Developer

B2B manufacturing-quoting platform — PCB/BOM workflows across 10+ enterprise contracts.
  • Replaced a hardwired AWS-S3 dependency with a provider-agnostic object-storage abstraction — one interface, swappable S3/GCS/Azure/MinIO backends chosen by a single env var with zero application-code changes — unblocking sales to regulated and on-prem customers.
  • Removed all cloud SDKs from the storage path, hand-rolling AWS SigV4 and Azure SAS request signers on Node crypto, pinned against published known-answer test vectors. Delivered across ~9 stacked PRs with an ADR and a mirrored Rust implementation.
  • Fixed a lost-update race producing duplicate quote line numbers across two external ERP integrations — shipped an atomic-counter fix, then discarded it and re-architected ownership so the ERP assigns line numbers and the platform syncs them back: Postgres advisory locking, idempotency under Temporal retries.
  • Designed a two-tier AI agent fleet automating the team's development loop — read-only scanners triage tickets and PRs into one ranked brief; human-gated executors carry work to a draft PR that structurally cannot merge without sign-off.
  • Built a two-layer visual-regression system — deterministic Playwright capture/diff plus a multimodal AI reviewer that reads composite images and reports in plain language what changed; advisory by design, it never blocks and never approves.
  • Introduced Clean Architecture and SOLID across core services — including a dependency-inversion presentation that became the basis for the storage abstraction above.
