  • Own production quality through tracing, evaluations, monitoring, metrics, and failure-mode analysis—balancing reliability, safety, latency, and cost to accelerate launches by 35% and sustain 99.2% uptime.
  • Partner across sales, engineering, product, security, and executive teams; lead 12 cross-functional solution engineers while contributing to 98% positive customer ratings and 85% contract renewal rates.
  • Turn field problems into reusable architecture, playbooks, and workshops that reduce time-to-value by 40%; ranked in Microsoft’s top 10% across a $40M+ portfolio and exceeded personal KPIs by 180%.

Lead Solutions Engineer — Payments and Cloud

VoPay · Vancouver, BC

  • Led discovery with 70+ monthly prospects, turning payment challenges into Python-based prototypes and tailored workflows that increased conversion by 60% and reduced sales cycles from 120 to 75 days.
  • Built Python and API integration workflows that automated troubleshooting, halving post-sales implementation time and reducing support tickets by 40%.
  • Turned recurring customer needs into reusable virtual labs and interactive demo environments used by 400+ prospects, accelerating time-to-value by 30% and contributing to 30% pipeline growth.
  • Promoted to Lead in eight months after driving $5M in year-over-year growth and exceeding KPIs by 220%; led four Solutions Engineers across three verticals and signed partnerships with Sage, Webull, and Mastercard.

Technical Co-Founder & CTO

Transcend · Vancouver, BC

  • Co-founded and built a Python-based product and analytics platform for 200+ ecommerce clients, owning product strategy, system architecture, and production delivery from zero to scale.
  • Developed product-recommendation, ad-spend-optimization, and product-research solutions that increased revenue by 85%, deal sizes by 60%, retention by 50%, and engagement by 300%.
  • Led and mentored an offshore engineering team while scaling annual recurring revenue past $2M at 170% year-over-year growth; the company and platform were ultimately acquired by a leading ecommerce competitor.

Technical writing

Build notes from shipped side projects—focused on the architecture, tradeoffs, and edges that matter once an idea meets a real workflow.

Technical note · APIs

Exporting Google & Meta Ads Data Without Timing Out

The architecture behind an asynchronous Apps Script pipeline for pulling ad data into a durable reporting workflow.

Technical note · Data engineering

A Research Workflow for the Facebook Ad Library

Have an ambitious problem?

Let's turn ambiguity into something that ships.

I'm always happy to compare notes on enterprise AI, forward-deployed engineering, product architecture, and the work of moving prototypes into production.
