At Toddle, I own the backend for the company's most crucial product, used by 2,500+ organizations and 5.3M+ users. I was promoted to Senior Software Engineer within three years.
I rearchitected a core module's backend by redesigning its PostgreSQL schema and migrating live production data with zero downtime. The work made reads 50% faster and reduced reported Sentry issues by 60%.
I also built a real-time monitoring and control system using Node.js, AWS Lambda, WebSockets, and event-driven pub/sub. Adopted by 600+ organizations as a paid add-on, it drives 35% of the module's revenue.
Earlier at Toddle, I implemented an asynchronous task-processing system handling 60K+ daily tasks across seven regions and owned the Safe Exam Browser integration. At SourceFuse Technologies, I built and maintained a vendor management app for Rakuten Inc. and integrated a contract manager tool with Jira, cutting contract management time by 70%.
