Design and implementation of a fault-tolerant microservice architecture and DevOps infrastructure from scratch. • Designed and implemented a microservice architecture in Go, focused on scalability and reliability. • Developed key microservices: • Payment service integrated with Stripe • Notification service using Kafka • Communication service built on gRPC Streams • Order history and API Gateway powered by Envoy • Designed a normalized PostgreSQL data model and implemented interactions with external systems via gRPC-gateway. • Configured notification queues on Redis Streams, ensuring guaranteed message delivery. • Built an admin control panel to simplify project management for the operations team. • Adopted a GitOps workflow on Kubernetes, automated deployments with ArgoCD (Google Cloud), and used Lens for fine-tuned cluster management. • Created and documented Kubernetes manifests (Service, Deployment, ConfigMap, etc.), standardizing the project infrastructure. • Integrated an observability stack (Grafana, Loki, Prometheus, Jaeger) for metrics, logging, and request tracing. • Contributed to business analysis, helping optimize processes and improve development efficiency.

In my role as a Go/Rust developer at Crypto Shark, I specialize in building high-load distributed systems for cryptocurrency applications. My work involves designing microservices that facilitate real-time market analysis and data aggregation from multiple exchanges. I focus on optimizing performance and ensuring system resilience, which is crucial in the fast-paced crypto environment.

Development and evolution of a corporate platform, migrating from a monolith to a microservice architecture. • Maintained and enhanced a monolith built with Fiber (FastHTTP), playing a key role in architectural refactoring into microservices. • Designed and integrated PostgreSQL and S3, ensuring reliable data storage and optimized access. • Implemented a role-based access control system with JWT and OAuth 2.0, adapted for a complex HR agency ecosystem. • Developed and deployed a WebSocket Hub and Builder, enabling stable real-time bidirectional communication with clients. • Integrated with 1C, Bitrix24, and external APIs, standardizing data exchange across services. • Built an internal security system, including activity auditing and access rights management. • Wrote and maintained tests (unit, e2e, mock), achieving high coverage of critical modules. • Containerized the project using Docker, and implemented a CI/CD pipeline via GitHub Actions. • Actively participated in sprint planning, defining business requirements, and tracking delivery timelines.

• Developed robust REST APIs using Java and Go, enhancing backend functionality for various projects. • Collaborated with clients on Upwork to deliver tailored backend solutions, ensuring high-quality results. • Gained hands-on experience with real-world backend systems and database management, improving technical proficiency.
