Senior software engineer and system architect focused on backend platforms,
schema-driven systems, and AI developer tooling.

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

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

Telegram ↔ tmux bridge for Claude Code: 1 topic = 1 window = 1 session

A substantially rewritten fork driven by daily use — not a cosmetic diff.

• Telegram bot as the interface for Claude Code sessions
• Each conversation topic maps to a tmux window and agent session
• Cleaner internal structure, more predictable agent workflows
• Practical fixes over experimental features

Schema-driven JSON API platform (Symfony + PostgreSQL)

BareAPI explores schema-first APIs, versioned JSON objects, and long-term data evolution.

It originated as an R&D effort around schema-driven metastores and grew into a functional platform.

Maintained, but not my primary focus.

Simple task runner in Bash for all projects around the world

A minimal, portable task runner — just Bash, no dependencies. Define project tasks in a Taskfile and run them anywhere.

Bunch of tools for easy Docker development

Makefile-based tooling for local Docker workflows — spin up, tear down, and manage dev environments without friction.

Opinionated Docker images built the way I use Docker

Alpine-based images for PHP/Apache, MariaDB, Laravel, and more — small, predictable, and production-oriented.

PRs and discussions welcome — especially around DX, tooling, and architecture.

These are real-world tools, not tutorials. Some projects are experimental or evolving.
