Staff Software Engineer @ DataRobot, based in Kyiv. I care about the software delivery process as much as the software itself, so a lot of my work ends up being CI/CD pipelines, developer tooling, and infrastructure as code that make everyone else's day-to-day shipping faster and less painful.
- AI Agents & Applications: building agents, and the runtime and serving layer that keeps them up
- Developer Experience: building automation and tooling that removes friction from everyday engineering work
- CI/CD Pipelines: designing pipelines and GitHub Actions that keep releases fast and reliable
- Infrastructure as Code: Pulumi and Terraform for provisioning and managing cloud resources
- 🤖 datarobot-agent-skills: skills that bring DataRobot platform capabilities to coding agents. I work on the CI/CD skills and the repo's review automation
- 🔀 review-router: a GitHub Action that automates code review routing based on CODEOWNERS
- ⚙️ dotfiles: my shell, Git, and Claude Code setup
- 🧪 macuitest: a functional and UI testing framework for macOS applications
On Agentic Engineering, notes on building, testing, and shipping agent systems:
- How I set up Claude Code: permissions for hard stops, an output style for tone, CLAUDE.md for judgment, skills for depth
Shell and Git setup notes:
- Shell startup: from 5s to 140ms: lazy-loading NVM and virtualenvwrapper, deduplicating compinit
- Zsh setup with Oh My Zsh: Powerlevel10k, plugins, and modern CLI replacements
- Signed Git commits with GPG: why and how to sign every commit
Field notes, stories from running real systems in production:
- Review Router: the GitHub Action that learned to review: CODEOWNERS routing, an AI reviewer built on Claude Code, and what's still unproven
- RDS Postgres 12 to 16: what Blue/Green doesn't warn you about: from about $650 to about $165 a month, and every place the upgrade broke
