Independent product designer and engineer

I design and build complex software that's easy to use.

I work across product decisions, interface design, and the code that ships to production.

Selected work

A few products I work on.

They range from a campaign editor to payroll and employee software. In each one, I work on both the product and the code.

01Marketing automation

DropUI

DropUI makes campaign creation approachable even for people with no experience using marketing tools. The platform covers popups, bars, embeds, feeds, WhatsApp, and web push, with email and SMS coming next.

02Payroll and HR system

P88-KaPla

P88-KaPla supports day-to-day payroll and HR work: employee records, time and attendance, calculations, payroll runs, and Polish ZUS, PIT, and GUS reporting. It also includes a multi-window workspace, detailed permissions, reports, and an AI assistant that only works with data the current user may access.

  • TypeScript
  • ASP.NET Core
