At First Bit, I designed and implemented a custom Project Calculation Engine integrated into the core ERP system. I also developed database models and real-time data synchronization to support engineering and procurement productivity. I engineered analytical datasets and used ClickHouse and complex SQL to aggregate transactional data, optimize reporting pipelines, and support business decisions. I also authored technical specifications and architectural blueprints for engineering and development teams. At Groupe Atlantic, I managed an integration project connecting Procurement and Warehouse modules with WMS handheld devices through REST APIs. I built Yandex DataLens dashboards from scratch, including Sales Matrices, Employee Efficiency, and ABC/XYZ analysis for more than five departments. Earlier, at Corada Consulting, I gathered and formalized business requirements, documented system behavior, and conducted manual system and integration testing. At Rival Group LLC, I supported database infrastructure, including Microsoft SQL Server administration, backups, migrations, and query-based troubleshooting.
