   At TrueIGtech, I work on building and scaling backend systems that power real-time iGaming and payment platforms. My focus is on high-performance services, optimized database queries, scalable reporting, and production-grade reliability.Key Contributions:Scalable API Services: Engineered backend services capable of handling millions of daily requests and 100k+ concurrent sessions with low latency and high availability.Database Performance Tuning:Migrated from ORM-heavy queries to raw SQL with CTEs, joins, and window functions, reducing query times from 5–10s to under 500ms.Applied PostgreSQL partitioning, indexing, and VACUUM/autovacuum tuning to improve query efficiency on multi-billion-row datasets.Removed reliance on materialized views by rewriting logic to fetch directly from base tables without losing performance.Optimized Query Layer: Built a dynamic SQL engine supporting filters, pagination, and aggregations in complex reports (e.g, players, transactions, leaderboards).Asynchronous Processing: Offloaded heavy tasks (CSV exports, cashback expiration, marketing campaigns) to BullMQ workers, improving API response times by over 40%.CRM & Marketing Automation:Designed a CRM module integrated with SendGrid Marketing Campaigns to manage player engagement at scale.Automated segmentation, list creation, and bulk uploads for up to users per campaign.Implemented job scheduling with BullMQ, enabling batch campaign processing without blocking the main API.Streamlined transactional and promotional email workflows using SendGrid’s dynamic templates + backend service layer.Payments & Transactions: Built secure, tokenized deposit/withdrawal flows integrating AptPay, Fyntek, and PaySafe for large-scale real-money operations.Production Reliability: Implemented caching layers, connection pooling, retry logic, and background monitoring to ensure stable production uptime under heavy load.
