At NDA Retail Group, I architected and delivered a centralized Calculation Management System for demand-calculation workflows. I also built an asynchronous task-aggregation and batch-write framework that reduced preprocessing for one distribution center across 230 suppliers from five minutes to 230 milliseconds.
I introduced Apache Ignite caching and parallel Compute Tasks, reducing that center’s calculation time from 30 minutes to 11. I also implemented transactional outbox and inbox patterns with idempotent processing for effectively exactly-once interaction with the Calculation Platform.
At DXC Technology, I developed and supported checkout, basket, and delivery-slot reservation features for Ahold Delhaize. I increased stable email-processing throughput from 15 TPS to 50 TPS and contributed to failed-order orchestration that increased retry speed and throughput by 30%.
Earlier, I delivered financial-data microservices at Citigroup and a document-exchange microservice at VTB. I began my career in automation and control, programming PLC systems and integrating building-control protocols.
