About

I design backend systems for clarity and easy maintenance, while ensuring my frontend work is optimized for security and application performance. I build and manage the containerized infrastructure that keeps applications scaling seamlessly. I am a loyal team member and can work autonomously, committed to delivering fast code and systems that simply work to industry standards.

Currently available for freelance projects and full-time or part-time employment opportunities.

  • Full-stack development — Ruby on Rails, Python, Node.js, Vue.js & more
  • System architecture design and platform engineering
  • MVP development and containerized infrastructure
  • DevOps, CI/CD pipelines, and cloud migrations
  • Technical leadership & AI-augmented team mentoring

My side projects often explore security and privacy — building tools that make safe, privacy-respecting data handling easier.
