Jan Mirecki
Frontend Developer

I am a Frontend Developer and a Product Designer.
I graduated in Product Design and after 4 years of professional experience as a UI & UX designer, I switched to a full-time developer role in 2015.

I work mostly with React, TypeScript & UI Design. I'm interested in high-quality projects focused strongly on the design, dedicated to regular internet users. I would be particularly happy to cooperate on a design system project. Other fields of my current professional role interests: QA, PM, and Product Designer.

In May 2024, I moved from Warsaw to Oslo, and since September last year, I have been learning Norwegian.
I love Norway for its landscapes and vast mountain trails, and it was here that I caught my first fish early this spring 🎣.

In my free time, I like to tinker, support friends with their projects, ride my motorcycle, climb, ski, and travel in my homemade micro rv. Recently, I started learning to skateboard, which brings me a lot of joy.
I am very fond of coffee, kombucha, and bread of my own baking.

    Senior Frontend Developer • Consultant • Architect
    Sztorm Jan Mirecki

    As a freelancer I'm cooperating with various parties, supporting commercial and non-profit projects. I have worked on projects supporting refugees. I organized a group of IT volunteers called WebScouts and supported more or less formal NGO organizations and grassroots initiatives. Together, we took part in accelerating the delivery of a Polish government website to support Ukraine. I led UX design exercises at the SWPS University in Warsaw, Department of Psychology and Computer Science. Commercially, I worked on the SAP UI for the US-based company – Corevist as a React Developer. Previously, I coordinated the redesign project of the web and mobile platform for Biletomat.pl, part of the Time For Friends Company. In this role, I led a team of designers, developers, and marketing professionals from a technical, coordination, and visual perspective, reporting directly to the company's management. Currently, I am coordinating work on a reservation system for facilities, where I am responsible for the frontend, design, and project management.
