Senior Backend Engineer with 14+ years of experience designing, building, and operating production-grade backend systems, with deep expertise in Ruby and Ruby on Rails. Strong focus on system architecture, performance, reliability, and long-term maintainability in real-world, high-traffic environments.
Extensive experience building API-driven systems, distributed workflows, and asynchronous processing using PostgreSQL, Redis, Sidekiq, and messaging systems such as SQS, Kafka, and RabbitMQ. Proven ability to design and evolve systems that support complex operational processes without becoming brittle or over-engineered.
Solid background in automation and workflow optimization, including the pragmatic use of orchestration tools when appropriate, while maintaining clear system boundaries and custom backend logic where it adds long-term value.
Early career in QA automation and software testing strongly shapes my engineering approach: emphasis on testability, predictable failure modes, and reliability by design. Comfortable working across CI/CD, DevOps, and cloud environments (Docker, AWS), and collaborating closely with product, QA, and infrastructure teams.
Used to working autonomously as a contractor, taking ownership from problem definition to production delivery, and making conscious trade-offs between delivery speed, technical quality, and sustainable system evolution.
