I contributed to distributed systems, allowing sellers to expand their business to other countries with a "single click" while preserving their revenue, no matter where they sell. The scope of this project impacted thousands of sellers across 10+ countries.

This system is a robust workflow orchestrator integrated with key internal services, providing a user-friendly UI that helps sellers trigger expansion and observe progress.

This tool allows sellers to extend their customer base and simplifies bootstrapping of new markets by copying offers from more mature marketplaces.

I worked on a Cloud Development Kit (CDK) construct library that allows users to design a robust monitoring infrastructure based on a simple declarative code. The library identifies correct metrics, creates nice-looking dashboards and alarms, and attaches trigger actions like cutting a ticket.

Using this library can save several person-days per app and increase operational excellence. The alarms provided are inspired by big tech best practices and real production incidents.

By 2023, the library had been used by at least 6,000 internal projects and had over 250 stars on GitHub.

I created and am maintaining a custom ERP system for the most prominent Czech manufacturer of windows for trams and buses. I have been developing the app and working closely with the company's production manager. The features include store management, orders, invoices, bill of materials, simple production planning capability, and reports.

More than five office workers have used the product for over ten years.
