- Built a configurable graph-based loyalty rules engine for transaction processing — config-driven, ordering-aware, and used as rollout infrastructure for product features
- Developed migration tooling supporting dual loyalty providers during Chevron's OpenCommerce transition
- Introduced .NET Aspire for local development orchestration, replacing manual multi-service startup with a single command workflow
Vitalii Prokopchuk
Senior Software Engineer — Distributed Systems — .NET & Azure
Senior Software Engineer with 14+ years designing and scaling distributed systems. Deep expertise in .NET and Azure, but pragmatic about technology choices — I select tools based on the problem and have shipped production systems with Node.js, React, ML.NET, and iOS when appropriate.
About
14+ years shipping systems at scale
Currently at PAR Technology, building backend infrastructure for Chevron's fuel retail ecosystem. The platform powers mobile apps and digital services used by millions of customers. My focus is transaction processing, loyalty systems, and developer tooling. One concrete improvement: introducing .NET Aspire to our local dev setup, which eliminated a lot of manual multi-service startup overhead.
Before that, four years at Strategic Vision building analytics platforms for the automotive industry — NLP pipelines over large-scale consumer survey data (free-text and voice responses), and real-time visualization tools used by major manufacturers to interpret market research at scale.
I also co-founded LetMePark as CTO, building the full platform from scratch. It grew to connect drivers with parking facilities across hundreds of locations in Spain and over a thousand across Europe.
I'm particularly interested in distributed systems, developer tooling, and the practical side of AI in engineering workflows. Outside of work I enjoy basketball, board games (especially Terraforming Mars), and keeping up with new tools in the dev space.
