• Senior developer on a team maintaining 8 high-traffic banking platforms • Modernized all 8 .NET Framework projects to .NET 8: migrated linq2db to EF Core, containerized core services with Docker, and restructured the codebase around Clean Architecture and DDD. • Automated deposit rate scheduling - moved a recurring task off frontend developers (4-6 hrs per update) onto a content manager (30 min), cutting operational cost by 44×.

• Built a standalone Redis-backed caching service used across a 6-microservice returns platform - exposed efficient get/store APIs and handled concurrency through Redis locking. • Owned the integration service connecting MS Dynamics 365 (CRM and ERP) and external logistics providers for real-time returns processing - modernized it from .NET Framework to .NET 7, cutting median processing time from 1.5 minutes to under 15 seconds.
