Daniel Zotkin

I’m a Golang-focused backend developer who builds secure, high-load microservice architectures. I designed and implemented a real-time communication platform in Go from the ground up, including robust authentication and traffic encryption.

In my work, I combined multiple services using gRPC, WebSocket, RabbitMQ, and PostgreSQL to deliver reliable communication across 8 microservices. I also implemented fault-tolerance patterns like Circuit Breaker and Retry to strengthen resilience under failure conditions.

Beyond clean code, I took on leadership responsibilities by managing a team of 3 developers—distributing tasks, conducting thorough code reviews, and aligning execution toward delivery. I’ve also engineered RESTful APIs in Node.js for a career guidance platform and built a loyalty system in C#/.NET integrated with POS hardware for financial transactions.

I bring practical DevOps experience too: I configured Nginx as a reverse proxy, automated deployment pipelines with Python and Bash, and reduced deployment times from 40 minutes to 8 minutes. I round it out with Docker, system monitoring via Grafana, and a core stack centered on Go, microservices architecture, and reliable Linux-based workflows.
