I build high-scale backend platforms, APIs, and data pipelines with Ruby and Go.

I've built backend platforms for ADV Group, Local Kitchen, Rambler, and Balance Platform, using Ruby on Rails and Go to deliver analytics, fintech, food delivery, and infrastructure systems.

At ADV Group, I launched an e-commerce analytics platform from scratch, won 6 long-term clients and 15+ trial customers in its first year, and reduced complex report-query latency from roughly three seconds to under 300 ms. At Local Kitchen, I supported services handling 25,000+ daily orders and 400,000 active users, strengthened OTP authentication with fraud detection, and improved a Go push-notification service for campaigns reaching 100,000+ users.

I'm comfortable owning REST APIs, asynchronous workflows, data pipelines, testing, production support, and infrastructure tooling across PostgreSQL, ClickHouse, Kafka, RabbitMQ, Redis, Docker, Kubernetes, and GitLab CI/CD.
