At LADA Digital (LADA Tsifra), I’m the acting Tech Lead of the MDM system for lecar.ru. I designed and implemented services for vehicle configurations, VIN-based data retrieval, product applicability links, and dynamic product typing.
For product applicability links, our team designed a compact storage approach without a graph database, supporting 1,000+ RPS on 100+ GB of data. I also introduced the Saga pattern and wrote architecture decision records using C4 notation.
At 1C, I developed the data layer of 1C:Element, a low-code platform for business applications. I built its embedded query language with ANTLR4 and owned migration dumps sent between the core and gateway via gRPC, improving the reproducibility and visibility of update errors by several orders of magnitude.
