I'm a backend developer and AI Champion at MasterBorn in Wrocław. I work on payment integrations and backend systems with Node.js, TypeScript and AWS, and help teammates put AI to practical use.
My path through web development and DevOps shaped how I build: I care about reliable delivery, clear boundaries and what happens after the commit. I make developer tools and agent workflows, share what works with my team, and keep experimenting with the smart devices running in my apartment.
Share responsibility for the payments API of an accounting and tax platform. Lead the backend integration with a new payment provider for card and ACH payments, working directly with the vendor. Delivered partial payments, incremental changes to a legacy payments service and diagnostics for webhook latency. Earlier work included Shopify checkout integrations and an internal feedback application.
Maintained CI pipelines for Linux-based images for custom hardware and managed machines used for computer vision training. Worked with GitHub Actions, Docker/Swarm, Linux, GCP, Azure and Ansible.
Completed a structured DevOps learning path.
Resolved CI/CD and environment issues with Kubernetes, Jenkins, Docker and Red Hat Enterprise Linux.
Built a Slack integration for timesheet changes and employee availability, alongside Node.js, Express, Parse Server and MongoDB features and fixes.
As an AI Champion at MasterBorn, I create reusable plugins, document working practices and share agent workflows with teammates. I designed and built Autodev with AI: a Claude Code workflow that moves from requirements and Jira planning through implementation and pull requests, with human approval gates.
I also developed AI-assisted code review with independent verification of findings. My focus is developer tooling that helps people make better decisions and deliver reliable software.
Multi-Site Home Lab
A three-location home infrastructure connected by VPN, hosting services and automated builds with virtual machines and containers. A practical space for experimenting with networking, automation and reliable operations.
Connected Treadmill Dashboard
A treadmill and Apple Watch dashboard with workout history and activity analysis. Developed primarily with Codex, alongside Claude Code, with device-state handling validated on real hardware and a deployed Workers/D1 backend.
Photography Studio SaaS
A deployed full-stack studio management app built with AI assistance and coordinated through defined agent roles, task tracking and review responsibilities.
A Personal Agent Environment
Task-aware terminal titles, an fzf session picker, a local session viewer, and reusable skills and hooks for context across agent sessions.
Telemetry-driven Audio
A desktop experiment that remixes audio stems in response to Forza driving telemetry, with reactive effects and telemetry replay for repeatable tuning.
Music Festival at Home
Evolving prototypes for music-reactive home lighting, with WLED integration and web-based controls for experimenting with synchronization and effects.
Many Smart Devices
Comprehensive home automation system managing lighting, climate, security, and energy monitoring.
Clean & Fast
Minimal portfolio built with TypeScript and TailwindCSS. Fast, simple, no heavy dependencies.
Our four-person team built a research CRM prototype using organizer-provided synthetic data. It combined a contact graph and conference briefings with agentic retrieval-augmented generation (RAG) over ChromaDB through MCP tools, using Claude and Vercel AI SDK.
Our three-person team created an LLM-powered assistant that followed a group conversation and helped participants organize a shared trip. The prototype used Gemini Flash for interactions and Claude Code during development.
Compared LLMs and static analysis tools for Node.js vulnerability detection. Built SecOrchestrator to run evaluations using CVEFixes and OWASP Juice Shop.
Designed and implemented a DevOps pipeline using GCP, Terraform, Kubernetes and Docker.
