Hi!
My name is Vítek Meloun and I'm a Ruby on Rails developer from the Czech Republic. Over the years, I've helped clients from all over the world with their Ruby and Rails projects.
I like software that's fast, simple and doesn't track its users. Ideally running on servers you control, so you're not locked into some cloud provider.
Lately, I've been focusing on AI a lot.
I specialize in
AI Agents & Integrations
Agents that know company data and actually get work done, plus the setup that keeps them in check: own servers, private access for the team, and a log of everything they do.
Hermes · Pi · MCP · Claude · Codex · custom API gateways
Backend Development
Everything behind the screen of a web app: data, business logic, background jobs and integrations with other systems.
Ruby · Rails · APIs · Hotwire · HTMX · Sidekiq · Redis
Ruby and Rails Upgrades
Getting old apps up to date. Old Ruby and Rails versions stop getting security fixes, and the longer you wait, the harder the upgrade gets.
legacy Rails migrations · version upgrades · dependency updates · RSpec
DevOps & Infrastructure
Moving apps from expensive cloud services to servers you control. It's usually much cheaper and works just as well.
cloud exit strategies · self-hosted solutions · CI/CD pipelines · Docker/Kamal · Linux
