• Built a scalable synchronization mechanism using Go and Temporal for daily ingestion of 100GB+ of sales performance data and developed a load-balancing mechanism with Redis-based semaphores• Engineered a versatile Go library generating optimized PostgreSQL queries, supporting pagination, filters, CTE and union queries• Managed databases exceeding 3 TB of data, optimizing query performance through meticulous query plan analysis and strategic index implementation, ensuring system efficiency• Optimized database performance by transitioning from vanilla PostgreSQL to TimescaleDB and fine-tuning it, reducing query times for the largest tenant from 3 minutes to a mere 2 seconds• Implemented a database management strategy, including setting up replication for high availability, backups integrated into the CI/CD pipeline, load balancing with HAProxy and using pgBouncer for connection pooling• Engineered a Go library for efficient storage of versioned data in TimescaleDB hypertables, leveraging hashing techniques to eliminate duplicates• Pioneered an idempotent write operations system exposed as a GraphQL endpoint to ensure reliable and exactly-once application of changes• Implemented a real-time data consumption mechanism from Amazon SQS as a Temporal background task tuned for processing up to 3,000 messages per second• Designed and implemented a system of scheduled and on-demand generated materialized views with metrics aggregated at various granularities, resulting in an 88% reduction in query times• Designed and implemented a real-time notifications system using RabbitMQ, streaming RPCs and GraphQL subscriptions• Automated infrastructure deployment using Terraform and provisioned self-hosted database images with Packer and Ansible• Leveraged monitoring and observability tools such as Prometheus, Jaeger, Grafana, Sentry and PagerDuty• Engineered a framework leveraging Redux, Redux-Saga and Apollo dynamically generating GraphQL queries
