## About

```text
At T1 Group, Innotech, on the VTB Bank project, I architected and delivered three core fintech microservices from scratch, automating operational day closures, loan penalty resolutions, and corporate collateral data enrichment. I also created a transactional Inbox/Outbox pattern that handled 10,000+ messages per minute with zero data loss during horizontal scaling.

I cut REST API load on dictionary services by 30% with custom in-memory caching, reducing latency and infrastructure costs. I also led responses to critical production incidents, with an average resolution time under 30 minutes.

Earlier, I customized Elasticsearch source code to eliminate about $50,000 in annual licensing fees, and developed a reusable auditing library used across more than five microservices. At Secret Technologies, LLC, I remediated critical vulnerabilities and improved unit test coverage on key modules from 40% to 75%.
