Hi there, I'm lobner 👋
I’m a passionate Computer Scientist and Software Developer, specializing in building robust, scalable backend systems with a focus on Ruby on Rails. With years of hands-on experience in both greenfield and legacy projects, I thrive on solving complex architectural problems and optimizing for maintainability and performance.
- 🏢 Current Focus: Building data-driven applications with Ruby on Rails, leveraging SQL Server (MSSQL) for enterprise-level reliability.
- 🏠 Based in: Cross-platform world (Mac OS as my daily driver, Ubuntu for devops tasks, always with a Mac keyboard).
- Languages: Ruby, Go, Java, SQL (SQL Server), JavaScript, Bash, HTML5, CSS3, YAML, Markdown
- Frameworks/Libraries: Ruby on Rails, Minitest, FactoryBot, Hotwire, React (for occasional frontend spikes)
- Database: SQL Server (MSSQL), PostgreSQL (sometimes), Redis (for caching/queues)
- Dev Tools: Git, Docker, VS Code, tmux, iTerm2, Zsh
- Testing: Minitest + FactoryBot
- CI/CD: GitHub Actions, CircleCI
- OS: Mac (primary), Ubuntu Linux (secondary)
- BiQ/es_import: Streamlining data import pipelines for enterprise search solutions.
- rails-mssql-enhancer: Making Rails + MSSQL a first-class experience (coming soon).
- open-source-helpers: Useful scripts and tools for everyday dev workflows.

- Huge fan of mechanical keyboards—except I always stick with my Mac layout.
- Love reading sci-fi and exploring new programming languages for fun.
- Advocate for clear, expressive test suites and documented code.
