Sergio Rhettwind

Senior Go Engineer with strong commercial background in high-load backend systems
and hands-on experience as a full stack developer.

About

I work primarily on production systems in private commercial repositories. My daily work involves designing, implementing, and maintaining Go-based microservices with a strong focus on reliability, performance, and concurrency.

In addition to backend work, I regularly build and maintain web interfaces and tools as a full stack developer (JavaScript, React, Node.js).

Over the last years, I average 800–1000+ pull requests per year across multiple closed-source projects.

Public GitHub represents side projects, demos, and experiments only.

What I work on

  • Go microservices (market data, trading, execution, analytics)
  • Exchange integrations (REST / WebSocket)
  • Concurrency, synchronization, data consistency
  • High-throughput and fault-tolerant systems
  • Event-driven architectures
  • Web dashboards and internal tools

Tech stack

  • Backend: Go
  • Frontend: JavaScript, React
  • Runtime: Node.js
  • Databases: PostgreSQL, MariaDB, Redis
  • Messaging: RabbitMQ, gPRC
  • Infra: Docker, Kubernetes
  • APIs: REST, WebSocket
  • Other: Linux, Git, CI/CD

Open source & code samples

Due to NDA restrictions, I cannot publish production code. This profile may include:

  • architecture demos
  • isolated technical examples
  • tooling and experiments

I’m happy to discuss real production decisions, trade-offs, and system design during interviews.
