Development of a platform for insurance brokers allowing them to access their data from various sources after unification, correcting, and enrichment.Key Accomplishments:1. Refactored the enrichment framework to become more flexible and standardized. That allowed us to simplify the addition of new 3rd party integrations into the process and speed up the setup of the enrichment for a new type of entity.2. Redesigned the way the enrichment process works to respect the results acquired on previous steps before making calls to the next 3rd party integrations. It allowed us to join similar entities, increased the quality of the final results, and decreased costs for 3rd party services by reducing the amount of such calls.3. Updated a significant portion of the enrichment-related codebase to accommodate multi-tenant environments. This strategic enhancement promises cost savings on infrastructure by enabling the hosting of multiple smaller clients on shared servers.

Development of Insurance Platform for Brokers, Agents and Insurers.Key Accomplishments:1. Designed and implemented a server-side queue for parallel processing of diverse tasks and jobs. This innovation streamlined internal operations, optimized resource utilization, and eliminated deadlocks arising from concurrent resource access.2. Unified and simplified the two-way synchronization process between various servers. It made the sync processes more stable and manageable and increased the throughput which allowed us to provide services to a larger client base using the same resources.3. Played a major role in a significant system overhaul, transitioning from a monolithic architecture to microservices and adopting a multi-client-per-machine approach. This strategic transformation substantially expanded our client base and yielded considerable cost savings on server infrastructure.

Development and maintenance of IP-PBX based on FreeSwitch.Key Accomplishments:1. Successfully resolved all memory leaks within the JavaFX VoIP client and optimized it to work fast in a restricted environment (256 MB of memory).2. Implemented a comprehensive refactoring of the server-side listener for FreeSwitch events, enabling parallel processing of diverse event groups based on their characteristics. This optimization substantially increased the system's capacity to handle concurrent calls and events on existing hardware while optimizing resource allocation for additional tasks.
