Staff Software Engineer | Platform Engineering | Healthcare Systems

Staff software engineer, 10+ years in healthcare and finance. Built the CI/CD and AWS foundation at Intelerad that now runs 800+ global healthcare sites, starting from a fully on-prem platform with no automation in place. Earlier, designed Morgan Stanley's OTC Derivatives reporting platform from scratch. The work I'm most proud of is the cross-cutting kind. Architecture decisions, cross-team coordination, and mentoring engineers through the harder parts.

Work Experience

Tech Lead, Platform Services | Intelerad | Aug 2024 - Present | New York, NY
  • Rebuilt the client connectivity platform on AWS ECS, taking 800+ healthcare sites from a flaky on-prem VPN fleet to 99.9% network uptime.
  • Drove the Python 2 to Python 3 migration to completion across all platform services, unblocking automated CVE scanning and OS patch management fleet-wide.
  • Own architecture decisions across multi-quarter initiatives, breaking roadmap work into trackable epics and clearing cross-team blockers with SRE, QA, and product.
  • Mentor engineers through architecture reviews, pair programming, and onboarding, raising the team's autonomy so day-to-day decisions no longer route through senior engineers by default.
Senior Software Engineer, SRE | Intelerad | Jan 2021 - Aug 2024 | Montreal, QC
  • Led the core platform migration from on-prem to AWS ECS with Terraform and PostgreSQL, cutting release operations from multi-day per-site work to hours across 800+ clients and 10,000+ servers.
  • Built LCM Precheck 2.0, a REST API that catches connectivity and service dependency failures a week before maintenance windows, raising first-attempt deployment success from 50% to 80% across 800+ sites.
  • Migrated the Ansible automation platform to Kubernetes on AWS so job workers scale on demand and concurrent deployments are no longer bottlenecked.
  • Centralized secrets management with HashiCorp Vault and AWS SSM and rolled out TLS on the internal messaging bus, removing ad-hoc credential sharing and the unencrypted data path in our HIPAA-adjacent environment.
  • Cut per-build pipeline time by 25%+ by restructuring Jenkins around multi-stage Docker builds, parallelized image pushes, and layer caching.
Software Engineer, SRE | Intelerad | Apr 2019 - Jan 2021 | Montreal, QC
  • Established the CI/CD pipelines that let software releases reach healthcare clients worldwide, building the SRE foundation the team still runs on today.
  • Designed and built the HashiCorp Vault platform from scratch with Terraform modules for dynamic DB credentials, transit encryption, and AWS auth, validated against a live cluster with a Go integration test suite.
  • Owned the OS-level compatibility work for the CentOS 7 to RHEL 8 migration across package management, SSH key generation, and Ansible automation.
Software Developer (Consultant) | Morgan Stanley | Jan 2017 - Jan 2019 | Toronto, ON
  • Designed and built a low-latency data distribution system for Morgan Stanley's newly formed OTC Derivatives reporting team, covering Interest Rates, Credit, FX, and Options at millions of transactions a day with sub-second SLAs.
  • Built an automated trade reconciliation system that cut reconciliation time from 5 days to under 1 hour, with 90% better accuracy than the manual process it replaced.
