Experience

Tacel — Full-Stack Developer

2024 – Present

Toronto, ON

Primary developer of the company's internal operations platform — 15+ apps and services (14 Electron/React desktop apps, a Tauri 2 + Rust rebuild, 2 Next.js sites, Python/Node services) descending from one shared template I designed, plus a 9-package internal npm ecosystem that hot-updates modules in production without app rebuilds.
Built the end-to-end RMA (returns) lifecycle platform across three coordinated desktop apps — per-item approvals, dual-currency repair costing, credits, cross-app audit logging, barcode scanning, thermal-label printing; the shipping app alone spans ~200 IPC channels.
Stood up company-wide CI/CD on a $0 budget: GitHub Actions on self-hosted runners across 12 repos — Vitest coverage ratchet, Playwright Electron E2E, an AST-enforced "new functions need tests" gate, Semgrep SQL-injection rules — auto-deploying self-updating installers.
Engineered the data foundation: a self-healing Python ETL mirroring ~50 Sage 300 ERP tables hourly via per-row MD5 hash diffs; a custom cross-app SSO (named-pipe + one-time JWT) giving ~2-second pre-authenticated launches; fully offline AI tooling (Ollama RAG, on-device speech-to-text, two MCP servers).
Rebuilt Tacel.ca bilingual (EN/FR): bounce rate −25%, average Google position 9.6 → 6.1 (~54% organic-click growth), lead-gen inquiries +30% in 3 months.

Legacy Delta Technologies (LDT) — Founder & Software Engineer

2026 – Present

Toronto, ON · my own software company

Founded LDT and shipped TEMPO, a local-first touchscreen attendance kiosk deployed in production at a manufacturing company — a self-contained Rust (Axum) binary with SQLite and a React + TypeScript UI served by the binary itself (no Node.js at runtime), serial barcode scanning, offline-first storage, Chromium kiosk shell with one-command Raspberry Pi provisioning, and a management console for administration and reporting.

Selected Projects

Job Application Tracker (JAT)

sole architect & engineer

Chrome MV3 extension + Electron desktop app · private codebase

Shipped a local-first job-application tracking & intelligence platform across ~90 tagged releases — ~32,000 LOC: token-guarded REST + SSE server, SQLite with 13 forward migrations, and a 5-provider LLM chain (Anthropic, OpenAI, Ollama, Codex CLI, deterministic fallback) with graceful degradation; secrets sealed at rest, loopback-only API, injection/XSS guards.
Built an email-intelligence pipeline (Gmail/IMAP + LLM classification, evidence-quorum truth gating) that updates application statuses automatically; verified by a 479-case test suite + a DOM-replay harness with 36 real-page fixtures, all gated in CI with auto-built, self-updating installers.
