At Bell Integrator, I develop ProDoc, an electronic document management platform that automates B2B interactions between a bank and its counterparties. I implemented the Saga pattern across approval and delivery steps, with compensating transactions that resulted in zero inconsistent states in the document workflow over six months.
I also developed Kafka integrations for procurement and banking systems, including idempotent consumers and a non-blocking retry scheme. By adding composite indexes and refactoring resource-intensive reports to native SQL, I reduced average query execution time to 40ms.
On Bell Integrator’s banking solutions, I developed Java services and API integration modules, helped build an automated testing framework, and mentored two developers. I also integrated AI agents into daily backend workflows to automate routine tasks, support test coverage, and speed up documentation.
At Coherent Solutions, I contributed to Java products in insurance, advertising, and CRM. My work included microservices, database query optimization, third-party integrations, and unit and integration tests.
