Message

At Sigma Software, I design, develop, and optimize backend features for a programmatic advertising platform handling millions of real-time bid requests daily. I work on deal management, real-time bidding, and publisher monetization, and investigate production issues using distributed tracing and log analysis.

At Luxoft, I developed reusable Simulink libraries for heavy-duty machinery workflows and maintained Java components for a domain-specific language. Earlier, I developed embedded software at Stellantis and Tomus Soluções, including automotive powertrain software and IoT solutions for tracking and monitoring water-delivery trucks.
