Alfa-bank

● I lead the frontend in two infrastructure products that ensure the continuous operation of thousands of microservices within the bank. ● I work at the intersection of engineering, architecture and product approach, interacting with architects, analysts, DevOps and business. Microservices autogeneration platform: ● An internal SPA platform that allows you to automate the creation of new services according to specified parameters. ● The project affects all departments of the bank. My contribution: ● Developed the frontend from scratch: architecture on React + Zustand + Tailwind. ● Implemented: - Visual creation of services. - Drafts with autosave. - Authorization via Keycloak. - Mass assembly, installation and deployment of services. - Subscriptions and WebSocket notifications. - Implementation via WebSocket viewing timelines, information on mass builds, service deployments - Process automation reduced T2M (Time-to-Market) by 30–50%. ● Contributed to API and backend logic (Java), developed DX. Portal of metrics and subscriptions to deliveries: ● The platform aggregates data from all department projects and allows tracking deliveries, updates, builds and metrics — both in real-time and historically. My contribution: ● Transferred monolith (React) to monorepo (Next.js) from Turborepo, improved architecture. ● Built a system of subscriptions, signatures and real-time notifications. ● Developed a role model and rights management interface. ● Increased test coverage from 10% to 90%, reduced technical debt and increased type coverage to 99%. ● Increased user engagement +40% due to UX optimizations.
