Modernizing on-prem to Azure at IoT scale
Interim Director of Software Engineering · Sept 2023 – Apr 2025- Situation
- Packsize's platform still ran on-prem while the customer base had grown past 3,000 IoT devices and 2,000 customers, amid multiple CTO and VP transitions that left engineering without steady technical leadership.
- What I did
- Stepped in as interim director, defined the enterprise-wide cloud strategy, and architected a distributed, event-driven system on Azure using domain-driven design and bounded contexts — while onboarding and coaching the incoming directors in parallel.
- Result
- Deployment lead time dropped from weeks to minutes, change failure rate held under 5%, and mean time to recovery fell under 15 minutes, across the full IoT fleet.
