At Kid -KCorporation, I design system architecture and develop control panels for many roles. I integrate inventory control, cost calculation, and statistics modules, and create APIs for data exchange with 1C and Excel.
At Loomo, I led the design and implementation of a scalable e-learning platform architecture using Cassandra and PostgreSQL microservices. At Humo digital, I developed REST APIs and optimized Excel and PDF generation and database management.
