I’m a Go Backend Developer with commercial experience in backend engineering, microservices, infrastructure-oriented systems, and information security.

I have worked in several domains, including PropTech, Telecom, Cybersecurity, and Enterprise / GovTech systems. This background helps me design backend services with a strong focus on reliability, scalability, security, and maintainability.

I graduated with a degree in Information Security for Automated Systems, which gave me a strong foundation in secure software design, network security, system architecture, and risk-aware engineering.

My main specialization is backend development in Go. I enjoy building services that are not just “working”, but production-ready: observable, testable, maintainable, and suitable for real-world load.

I have hands-on experience with microservice architecture, REST APIs, gRPC, SQL and NoSQL databases, message brokers, Linux environments, Docker, CI/CD pipelines, and DevOps practices.

Languages and backend:

• Go / Golang
• REST API
• gRPC
• HTTP / JSON
• WebSocket

Databases and storage:

• PostgreSQL
• MariaDB
• SQLite
• MySQL
• NebulaGraph
• Manticore
• MongoDB
• ClickHouse
• Redis / Memcached

Infrastructure and DevOps:

• Linux
• Docker
• Kubernetes
• GitLab CI/CD
• systemd
• Nginx / Apache
• Kerberos

Message brokers and integration:

• RabbitMQ
• Kafka
• Event-driven architecture

Observability and reliability:

• Prometheus
• Grafana
• Logging, metrics, tracing
• Distributed systems debugging

Information Security:

• Secure backend design
• Authentication and authorization
• Network protocols
• Infrastructure security
• Security-aware architecture

I’m especially interested in backend systems where engineering depth matters:

• high-load backend services;
• distributed systems;
• microservice architecture;
• infrastructure automation;
• network and telecom systems;
• cybersecurity products;
• DevOps and Kubernetes-based platforms;
• reliable production-grade systems.

I have experience working across different business and technical domains:

• PropTech — backend services for real estate and business process automation;
• Telecom — network-oriented systems, service integration, and infrastructure-level development;
• Cybersecurity — backend and infrastructure systems with security and reliability requirements;
• Enterprise / GovTech — secure document workflow and enterprise-grade information systems.

This variety of domains helped me develop a practical engineering mindset: I care about clean architecture, predictable behavior, testing, observability, and long-term maintainability.
