About Me

Building Systems
That Last

Full-stack developer with 15+ years of experience designing and delivering enterprise-grade applications — from high-traffic CMS platforms to real-time manufacturing execution systems.

I specialize in Angular, TypeScript, NestJS, and Firebase, with deep experience in cloud architecture, real-time systems, DevOps pipelines, and CRM/ERP integrations. Currently Senior Developer at Damotech, I design end-to-end platforms spanning offline-first mobile apps, live production dashboards, serverless Firebase backends, and self-hosted Kubernetes clusters.

I bring both hands-on technical depth and leadership experience, having led engineering teams and driven architecture decisions on mission-critical, high-throughput systems.

SaaS · Safety Inspection · Mobile

Warehouse Safety Inspection Platform

Cross-platform web + iOS + Android SaaS for industrial warehouse racking safety audits, issue tracking, and repair management. Built as an offline-first field tool enabling inspectors to work without connectivity, with bidirectional sync running in background threads.

  • Offline-first sync via IndexedDB (Dexie), Web Workers (Comlink) & Firebase Firestore — full bidirectional sync with no connectivity required
  • Purpose-built 2D canvas rendering engine for interactive warehouse floorplan & rack elevation visualization with zoom, filtering, and drill-down flows
  • 20-step event-driven import pipeline via Google Cloud Pub/Sub choreography, ingesting CSV/ZIP/DXF bundles into Firestore with per-step concurrency tuning.
  • Bidirectional HubSpot CRM & NetSuite ERP integrations with HMAC-verified webhooks and nightly sync
  • 10-module Firebase Cloud Functions Nx monorepo — 200+ serverless functions across HTTPS, Pub/Sub, Cloud Scheduler, and Firestore triggers
  • Multi-tenant RBAC with Firebase custom claims — API key, Bearer JWT & session cookie auth modes

Manufacturing Execution System

Real-time MES managing the full production order lifecycle for two industrial manufacturing plants (Boisbriand, QC & Moberly, BC) — from drawing intake through packaging and shipping. Twelve specialized workstation UIs covering every stage of the production floor.

  • WebSocket + polling hybrid with Socket.IO, JWT auth, and RxJS debounced re-fetches for live production floor updates
  • Production KPI dashboards across 2 manufacturing plants (Canada & US) — daily throughput, EU backlog, and per-operation capacity across 30+ configurable production routes spanning welding, cleaning, robotic assembly, packaging, and shipping stations

High-Traffic · CMS · SOA · AWS

High-Volume CMS & Microservices Platform

Built and scaled a custom CMS powering hundreds of high-traffic client websites, processing millions of daily requests. Over 7 years at Seedbox Technologies, led the architecture evolution from a PHP monolith to a Service-Oriented Architecture across AWS and on-premise Linux infrastructure, ultimately taking on the engineering team lead role.

  • Custom CMS serving hundreds of client sites at millions of daily requests — architected for high availability with a core focus on sub-100ms response times
  • Drove the migration from legacy monolith to Service-Oriented Architecture, decomposing into independently deployable Golang and PHP services
  • RESTful and GraphQL web services on AWS (Lambda, API Gateway, AppSync, DynamoDB, CodePipeline) and on-premise infrastructure
  • Maintained complex database architectures across MySQL with Memcached caching layers, managing hundreds of millions of records
  • CI/CD pipelines via Jenkins, AWS CodePipeline, and Travis CI — automated testing and zero-downtime deployments across all client environments
  • Integrated Docker throughout the development lifecycle for environment parity; partnered with SysAdmins on server architecture and security hardening
