I build high-load Node.js microservices, payment systems, and production platforms serving millions of users.
Russian FederationWhat I'm looking for
At Icons8, I build and support high-load Node.js microservices for a digital-content platform used by millions, including a core service handling up to 25,000 RPS. I've delivered subscription billing and Stripe integration, moved webhook processing to RabbitMQ with retries and DLQ, and introduced CQRS in billing.
I also built observability with Prometheus, Grafana, and Telegram Bot alerts, integrated AWS S3 and Sharp image compression, and designed a content-generation microservice using OpenAI GPT and Stable Diffusion.
Previously at Let’s Dev, I developed backend services from scratch for a microservice-based language-learning product, designed APIs and PostgreSQL/MongoDB data models, improved search with PostgreSQL indexing, and configured automated CI/CD. I contribute through code reviews, production support, onboarding materials, ADRs, documentation, and technical interviews.
