Senior software engineer and system architect focused on backend platforms, data integrations, and agentic engineering.

I build tools I want to use myself — mostly CLI-first, reproducible, and designed to survive long-term evolution.

Run AI coding agents in isolated containers with access only to your workspace

• Podman/Docker-based isolation — agents can't touch your host system
• Git worktrees, tmux/byobu, SSH-friendly
• CLI-first workflow, designed for Claude Code, OpenCode, and similar agents
• Focus on safety, reproducibility, and developer experience

Shared MCP coding worker backed by OpenCode

• Dedicated worker for implementation, codebase exploration, diagnosis, verification, and independent code review
• Separates coding and review steps across isolated environments and models

Schema-driven JSON API platform (Symfony + PostgreSQL)

Explores schema-first APIs, versioned JSON objects, and long-term data evolution. Originated as an R&D effort around schema-driven metastores and grew into a functional platform.

Git workflow utilities in Bash

• git-wt — Create, prepare, and switch into a Git worktree in a single command: https://github.com/vojtabiberle/git-wt
• repo-manager — Lightweight CLI for managing multiple Git repositories: https://github.com/vojtabiberle/repo-manager

Portable dev-env and container tooling

• Taskfile — Minimal, dependency-free Bash task runner: https://github.com/vojtabiberle/Taskfile
• maker — Makefile-based tooling for local Docker workflows: https://github.com/vojtabiberle/maker
• docker-images — Opinionated Alpine-based images for PHP, MariaDB, and more: https://github.com/vojtabiberle/docker-images

• framework-charge-limit — KDE Plasma 6 widget for Framework Laptop battery charge limits: https://github.com/vojtabiberle/framework-charge-limit
• pwnagotchi-wifi-manager — Experimental Wi-Fi role manager and USB/IP display setup: https://github.com/vojtabiberle/pwnagotchi-wifi-manager
• web-archive-downloader — Download snapshots from the Wayback Machine: https://github.com/vojtabiberle/web-archive-downloader

• ccbot (heavily modified fork, no longer active) — Substantially rewritten Telegram ↔ tmux bridge (1 topic = 1 window = 1 session) for Claude Code sessions: https://github.com/vojtabiberle/ccbot
• Contributions and PRs to tools in the AI agent & terminal ecosystem (e.g. zj-radar, pohunek).

• Agentic engineering — structured workflows (SPEC → TASKS → AGENTS → TESTS → REVIEWS), sandboxing, and E2E verification
• Schema-first design & explicit contracts
• Evolvable data models & data pipelines
• CLI-first developer experience & reproducibility over click-ops
• Self-hosting & homelab (Proxmox, Docker/Podman, Linux)

Languages

• PHP, Go, Python, Bash, TypeScript

Backend & Data

• Symfony, Doctrine
• PostgreSQL, Snowflake, BigQuery, Supabase, Elasticsearch
• JSON Schema, migrations, validation, MCP servers

DevOps & Infra

• Docker, Podman, GitHub Actions, GitLab CI
• Proxmox, self-hosting, Linux (KDE Plasma)

• AgentBox & coding-worker — safe containerized execution and MCP orchestration for AI coding agents
• Data platform architecture & AI integrations at Keboola
• Schema evolution & CLI developer ergonomics
