Introduction

I’m Vasyl Melnychuk, a software developer passionate about building scalable systems and elegant solutions to complex problems. With expertise spanning backend development, cloud infrastructure, and modern web technologies, I focus on creating reliable, performant applications.

Background

My professional journey in software development has been driven by curiosity and a commitment to continuous learning. I’ve worked across various domains, from building microservices architectures to optimizing database performance, always seeking to understand both the “how” and the “why” behind technical decisions.

Expertise

As a software engineer with over a decade of experience, I possess advanced skills in software engineering, with particular emphasis on Ruby application development. My technical toolkit includes:

  • Programming Languages: Ruby, JavaScript, TypeScript, Python, Elixir, Groovy, Java
  • Frameworks & Libraries: Ruby on Rails, Sinatra, Hanami, Dry-rb, Sidekiq, Node.js, Vue, React, Phoenix
  • Databases: PostgreSQL (including PostGIS), MySQL, MongoDB, Redis, Neo4j, Elasticsearch
  • Cloud & Infrastructure: AWS, Google Cloud, Microsoft Azure, Heroku, Docker, Kubernetes, Terraform, Ansible, Linux server management
  • Messaging & Queues: Kafka, RabbitMQ, SQS
  • Architecture: Microservices, Service-Oriented Architecture, TDD/BDD
  • APIs & Integrations: REST, GraphQL, SOAP, SSO, OAuth, SAML, OpenID Connect

I believe in writing clean, maintainable code and building systems that are not just functional, but also observable, testable, and easy to reason about. I have experience managing the full development lifecycle without QA or Project Management overhead.

Interests

Beyond the day-to-day coding, I’m fascinated by:

  • System design and architectural patterns
  • Performance optimization and profiling
  • Developer tooling and productivity
  • Open source software and community collaboration

Currently

I’m always exploring new technologies and refining my craft. Right now, I’m particularly interested in cloud-native architectures, observability practices, and the evolving landscape of developer tools.
