Oleg Platonov

Motor insurance platform in an ecosystem serving 40M+ users. • Rolled out one external payment gateway across most partner insurers; it now carries the bulk of policy payments. • Own service boundaries: moved logic out of the monolith, merged over-fragmented services back. • Built fast renewal (a policy issued in under 30 seconds), the insurer ratings backend and cross-sell. • Upgraded dozens of services to .NET 10; shared GitLab CI, code style, automated checks. • First to adopt AI tooling in the team.

Backend services for policy issuance. • Integrated 5+ insurance companies into one issuance pipeline, each with its own contract and protocol (SOAP, REST, GraphQL). • Took part in migrating the services from MS SQL to PostgreSQL. • Built features and asynchronous processing on RabbitMQ. Promoted to Senior Backend Engineer in June 2025.

Front office IT systems of a retail bank with 14M+ customers. • Built the core backend of an internal release planning platform that aggregates capacity across all engineering teams; release planning went from several days to about 30 minutes. • Migrated the server codebase from .NET Framework 4.5 to .NET 7 and helped move from an enterprise service bus to microservices. • Built ASP.NET Core Web APIs (CQRS, MediatR), Quartz jobs, IBM MQ and RabbitMQ integrations.

Internal systems of one of the largest leasing companies in the country. • Built business logic: extensions to core scenarios, background data processing, REST and WCF integrations. • Proposed and rolled out one architectural approach to extensions in place of a separate implementation per developer. • Introduced code review to the team.

Automation projects for banks of VTB Group and Societe Generale. • Built business logic and integrations for internal banking systems: loan loss provisioning, credit deal monitoring, risk systems, loan control. • Started as a systems analyst: gathered client requirements, designed interfaces, integration flows and APIs, wrote specifications, then moved into development.
