ARTMO is a social platform for the promotion, curation, and sales of art. Currently, at 250,000+ users, it is challenging the current model of art sales through a commission-free approach. ARTMO's goal is to coexist with and support established art institutions by providing them with marketing tools while enabling independent artists and buyers worldwide to promote and resell art pieces.

In ARTMO, I worked as a co-founder and product lead. The platform ran a successful crowdfunding campaign through Companisto in 2020.


This is a project of a website and digital brand identity for MIA STUDIO, a Berlin-based sustainable fashion label.

The brand aims to revolutionize the dominant sizing system, free women from prevailing categories, and offer adaptive fits. MIA STUDIO's mission is to create garments that provide comfort, versatility, and confidence to modern and conscious women.

I designed and developed this Shopify-based digital solution by customizing a boilerplate theme. That included Liquid templates, CSS, JavaScript, and integrations of automated shipping solutions from DHL.

The project can be considered ongoing as I still provide biweekly improvements in collaboration with the stakeholders.

NEW MODELS Webdex 2020

During the pandemic, I was involved in the community around the NEW MODELS podcast, exploring the relationships between networked technology and culture. The media outlet has a thriving Discord that developed its own useful vernacular for understanding current events.

In an effort to share this knowledge, the community came up with a digital codex for new terms that emerged during the pandemic. My contribution to the codex was the screensaver. Under the pseudonym @localhost96, together with @jarilyn, we created a showcase of memes that stack up at a very fast pace whenever the user is not active on the screen.

School of Peace

This is a website I co-created with an exceptional coach and meditation expert, Emilia Dabrowska. The complete digital solution is based on WordPress and includes subscription integration with Stripe and PayPal; e-learning (LMS); native app integration with the REST API; and marketing materials.

The website is the primary touchpoint for the subscribers of the meditation service. The product includes 50+ guided meditations, a book, self-improvement materials, and weekly personalized outreach to the community.


The project I developed was a website for a renowned, Warsaw-based animation and CGI studio. The client's vision in this project required a lot of animation and memory-intensive DOM manipulation. Using CSS3 and a jQuery-based animation engine, Velocity, I developed a set of high-performance, fluid animations that work on different screen dimensions on the desktop.

Generative Painting

The project is an experimental application of design system tools to create abstract images.

The design challenge was to create a generator of images in the style of a certain visual artist. My pick was Franz Kline. The project started as simple reproduction. However, with added complexity, it began to generate randomized images that went beyond imitation of Kline's style.

Social Share | WordPress Plugin

This plugin displays the share buttons of selected social media accounts. It is available for posts, pages, and other custom post types. Users can change the size, color, order, location, and placement of buttons on the page. Buttons can show on any page, post, or custom post type. The plugin comes with a shortcode [ttsocialshare] displaying the buttons on any post or text widget on the page.


Designed and developed an end-to-end WordPress and React solution for an electric skateboard rental company. I created a simple booking plugin from scratch, along with WordPress REST API endpoints to call from the React app.
The front-end repo is available at github.com/krawc/ElektroDechy/tree/master.
