This project is a crowd-funding portal for real estate projects. On this site, admins can create a project made up of real estate stock options, including extra points and blockchain tokens. Users can purchase stock options for new real estate builds while gaining points and blockchain tokens after purchase confirmation. They can spend their extra points on discounts and other promotions while shopping.

Each purchase under Polish law must be confirmed by a qualified signature. The application generates PDFs with legal terms that later must be signed and validated.

An internal dashboard to maintain and monitor the lending of various clients. The client developed a bespoke lending algorithm that needed to be converted from various Excel files into a user-friendly intranet web dashboard.

ArtSee is an app targeted at blind and visually impaired people. The application is easy and intuitive, and its launch will be shortened to two clicks. The app works on a double click (the first click says what is under the given button, and the second confirms the selection)

The whole technology stack is based upon WebRTC, which enables peer-to-peer direct communication between people who visit the exhibition and curators that describe the art.

I did system architecture for the application based on the following:
• WebRTC for peer-to-peer communication wrapped in a Cordova mobile container
• Admin panel using Node.js, Express, and React
• JavaScript iBeacons library that was delivered by kontakt.io hardware provider
• Client application using React, Socket.IO, and WebRTC
• PWA as a feature

At the end of 2017, when progressive web apps (PWA) had matured, we added those as a feature, so now the user can experience the app without installing it on their device.

I did the software architecture for Tuszama, an application that meets the needs of Polish students. It efficiently and easily facilitates food orders during a long break.

The process of ordering food is very simple. Just create an account, choose the school, and order food. The application is available for three types of users: administrators, providers, and students.

Tuszama is connected to Płatności24 and has a subscription for account recharging.

This is a Meteor application that features:
• One line of JavaScript code in ES6 for the back- and front end

• Three types of privileges: administrators, providers, and clients
• Daily backups
• Google Maps API address verification
• Virtual wallet
• Sophisticated order process based on each school and provider-specific deadline
• E-payments
• Cordova iOS and Android with push notifications

I'm the founder of my own web development company. Our homepage is SilverStripe-based and features real-time video processing.

Okapi Cash is a remittance platform that allows Remittersto to send money home to their loved ones on most occasions instantly. Okapi Cash sends cash directly into users' mobile money accounts. Okapi Cash is fast, affordable, and secure.

Chart Features:
It uses a CSV file for data that the client uploads with a simple Laravel back-end and an “Upload new CSV file” button. Another useful feature is that it can present different categories on a Gantt-ish timeline chart. A user can choose specific time periods as “helpers” to show the right time period such as the first quarter, next month, and so on. It also provides a popup with more detailed information when clicking on an activity.

Tabanda consists of three designers: Malgosia Malinowska, Filip Ludka, and Tomek Kempa. They are architects who have always been fascinated by furniture design and utilitarian object design.

For Tabanda, I have prepared a website and shop based on Drupal with eCommerce solutions.

Website contains many bespoke implementation written from Skratch in Drupal D7 Framework.

For GAK, I created a Drupal-based website whose main task was to integrate and ease searches for events taking place within the institution's ten branches. The site was built to be responsive.

The main page features a calendar showing upcoming events, sorted by color depending on the branch. Next is a map with locations.

The main website contains an API that expose all the events to each branch. Every branch has a separate SilverStripe website that has a bespoke visual block composer that allows to build and style its own website.

All events information are take from the main page and the rest is maintained by the branches crew.

This project included the design of completely new IA, integrating several previously-unrelated websites in one with pictures of all the library branches and BIP, e-shop, a promotional video, and more. An intranet and public info services were included, and the multi-site structure was built on Drupal.

A social media wall is a live feed of social posts from sites like Twitter, Instagram Facebook, YouTube, LinkedIn, and more, displayed on any digital signage display. Social walls can be integrated in websites or totally independently.

This is a SilverStripe based project.

A Drupal site for an international street and open-air theater festival. It is designed to look fresh and new with a color and theme change every year, though the background mechanism remains the same. The site is easy to use and contains minimal necessary information, which in turn minimizes the need for scrolling.

Attendees can add files and photos, helping build the festival's presence, and the site is responsive for mobile viewing.

A website based on SilverStripe CMS.

Conference Bear is an easily accessible conference database that includes search functionality and the ability to view the program, speakers, and other details for a conference. The application is also equipped with a notification system, and is integrated with a Laravel-based REST API.

Multimedia content for a temporary exhibition at the Archaeological Museum in Gdansk. They've been conducting excavations in a historical part of the city, gathering thousands of specimens in museum warehouses. The exhibition reconstructs almost seventy pieces of historical—mostly leather—footwear using surviving fragments.

For the exhibition, I made a ten-minute film from start to finish and three ActionScript-based applications for touchscreen interaction.
