Sergei Deinego

Backend Developr with 15+ years of experience building scalable distributed systems, high-load architectures, and data-intensive platforms.

I specialize in designing production-ready backend systems from scratch, refactoring legacy monoliths into microservices, and building reliable event-driven infrastructures.

Key expertise:
Go & Python (expert level)
High-performance PostgreSQL design & optimization
Event-driven systems (Kafka, NATS)
ETL pipelines processing 30M+ pages/day
Full SDLC ownership — from business requirements to CI/CD in Kubernetes
Bots and webscrapes (telegram etc)


I focus on building systems that are scalable, observable, fault-tolerant, and aligned with business goals.

Open to senior backend / architecture roles where complex systems and data modeling matter
