Claude Community Warsaw

Welcome to the second Claude Community Warsaw meetup, a community-driven initiative built by builders, for builders https://claudecommunity.pl/

We share real stories of how we use Claude, Claude Code, and Claude Cowork in our daily work. No product pitches, no vendor talk - just honest experience from people who build with these tools every day.

Pizza and drinks are included and the event is free, sponsored by DataArt!

Your Claude Code Workflow Needs Architecture Too
What happens when your Claude Code workflows start accumulating their own technical debt? Sergii will share how familiar software architecture principles helped him rethink the way he works with Claude Code - with practical examples, unexpected pitfalls, and lessons learned the hard way.

One control plane for all your agents: running 50 Claude Code agents on real accounts, without them ever holding a key
Since spring I've been running my company on 50+ persistent Claude Code and OpenCode agents. They SSH into servers, query production databases, send email, ship PRs and delegate work to each other, and they never see a single secret. To make that possible I built ARPOS: a self-hosted operating system for agents. It handles the runtime, persistent agent "desks", credentials injected server-side (CLI, API, SSH, SQL, web logins), one inbox for human approvals, and cost per agent. On top of it you can build anything: a software factory, agents for clients, autonomous teams. My own software factory runs on it and builds ARPOS itself. Live demo, plus the honest lessons.

Speakers
🎤 Sergii Luchko — Software Architect, Tech Lead and Senior Full Stack JavaScript Engineer with 15+ years of commercial experience designing, modernizing and delivering web platforms.
🎤 Bartłomiej Szczygło — AI engineer, full-stack developer and solo founder (Atos Software), with a Computer Science background from Warsaw University of Technology and FH Salzburg. He keeps sharpening his edge in agentic AI through programs like AI_devs, 10xDevs and AI Tech Leaders. Today he runs his company and client projects on a team of AI agents, on infrastructure he built himself: ARPOS.
