• Managed and led a team of 11 engineers - Data Engineers (team of 2), Backend Engineers (team of 4), and DevOps (team of 5). • Helped design and build a data pipeline for analytics products. • Reduced the cost of infrastructure by 40% by optimizing database queries and migrating EKS to ARM processors. • Planned and implemented improvements, led backend meetings, improved culture by facilitating more open communication, and set up code reviews and ADRs. • Designed a new CI/CD pipeline for a microservice-based project, enabling the team to move from a multi-repo/multi-branch Git workflow to trunk-based development. The team doubled productivity, sped up builds and delivery, and decreased technical debt by simplifying the management of dependencies. • Educated myself about the core concepts of product development to improve communication with the new Head of Product, resulting in the successful launch of a new major product feature that stalled for six months. • Redesigned the developer workflow for 11 engineers to align with industry best practices (automated testing, gradual rollouts to production, dark launches) which lead to faster iteration cycles. • Dramatically improved the team's productivity, and halved the time to deliver changes from weeks to days.

• Designed, built, and continues to maintain a real-time system for single-directional and bi-directional data integrations with enterprise-scale providers of electronic medical records (EMR) that can process over 200K+ events in under 6 minutes fed from partner's FIFO queue and under 10 seconds for a standard queue. • Created infrastructure migration plan, including DevOps team, to migrate from AWS EC2 to k8s to AWS EKS, improving scalability, and reliability and reducing cost by 40%. • In a crisis mode, designed and built a secure microservice-based cloud system compliant with HIPAA during the starting months of the pandemic which handled more than 100K+ video calls a month during the peak of the pandemic. • Migrated 20+ services from REST to federated GraphQL. Now API consists of 20 REST routes (mostly webhooks) with 40+ services. GraphQL increased developer productivity by 2-3 times, decreased infrastructural complexity, simplified and standardized partner integrations. • Managed 2 new hires for the backend team - created initial processes and documentation for onboarding. • Fully automated management of infrastructure using Terraform and Serverless CI/CD to maintain 40+ microservices and 120+ Lambda functions, automated most of the maintenance.
