Responsibilities ● Design and development of core loyalty platform services. ● Solution architecture development and decision defense at tribe architectural committees, ADR, documentation, and technical regulations. ● Leadership of 3 teams (≈15 people): sprints, decomposition, task setting, team synchronization, mentoring, and release cycle. Achievements: ● Launched Kafka as an ESB/integration bus for the external loop as a project manager: coordinated requirements with customers, designed the target architecture, and ensured production deployment. ● Designed and secured a new user consent service: template editor, consent collection and statistics, and uploading to DWH. ● Designed and launched a file integration service to replace a legacy solution, serving as architect and team lead: standardized contracts, ensured the migration of file integrations to the new product (approximately 500), and ensured operational visibility and manageability. ● Reduced time to market for teams through a streamlined release cycle: from 3-4 weeks to weekly releases.

Responsibilities ● Design and development of a SaaS EHR platform (MIS) from scratch for a federal clinic network. ● Architecture and development of backend services. ● Management of two teams: a full-stack team and mobile development (iOS, Android). ● Participation in product development with doctors (primary users): online payments, subscriptions, telemedicine, personal account, mobile app support. Achievements ● Implemented a production platform from scratch for a clinic network: 9 branches in different cities and time zones. ● Built an integration circuit with the MIS for external partners. ● Launched key client product modules of the platform: online payments, subscriptions, telemedicine, patient personal account. ● Implemented observability (ELK + Prometheus/Grafana).

● Developed an HR aggregation service (a unified employee profile) and an event bus for interactions between platform services. ● Designed and promoted a centralized authentication and authorization service as an internal shared solution. ● Wrote a library for distributed log tracing in microservice environments. ● Developed a GraphQL API and Angular interfaces for the bank's internal products. ● As part of an internal startup accelerator, brought an IoT device project to the MVP stage: assembled a team, conducted CustDev, developed CJM, and defended the project.

● Developed a corporate lending system using ASP.NET MVC / Web Forms. ● Covered the code with unit tests (NUnit) and integration tests (Selenium); CI/CD via Atlassian Bamboo.
