  • Taxi Robot Control Station (Development)

    Wrote an algorithm in a web application which controls robot movements in a warehouse. It was meant to help warehouse workers move heavy cargo in an automatic and time-efficient manner. The algorithm was tested in real environment with multiple robots being used simultaneously.

    Technologies used were Groovy on Rails, MySQL, Groovy, HTML5, CSS3, JavaScript, jQuery, GORM, GSP

  • Hotel Application (Development)

    Created a web application used in hotels where various types of workers were able to log in and monitor guest reservations, make orders to vendors, monitor the number of items in the hotel reserve or in the kitchen, and more.

    The guests could also log in and give orders to the hotel staff using the application and monitor their expenses.

    The framework used was Groovy on Rails.

  • Swarm Algorithm Simulator (Development)

    Created a 2D simulator with a GUI in MATLAB for a swarm algorithm where N robots were released into a dynamically created environment: simulating a wind farm on a sea surface, and inspecting each of the windmills in a time efficient manner. Used various cool algorithms such as A* and BFS, also used dynamic programming concepts for performance optimizations.

    The robots acted as single units, not knowing what the other was doing at any given time. They had to communicate with each other both directly (when and if they meet) and by using the environment (stigmergy) exchanging newly gathered data.

  • Customer Information (Development)

    Created a desktop application which serves as a simpler version of a CRM which shows all the client data retrieved from the company's MS SQL Server database.

    Technology stack was WPF and .NET.

  • Employee Manager (Development)

    Worked on a project for managing employees. Created an authentication system using JWT tokens. The application enables managing employees depending on their organization and department.

    Technology stack was MongoDB, Express.js, TypeScript, Angular 4 and Node.js.

  • GeekCard (Development)

    Developed the front-end part of a web application used for paying various bills using the so-called GeekCard. The user orders the GeekCard which can then be used for payments at various shops.

    Technology stack was TypeScript and Angular 4.

  • D3.js Charting Library (Development)

    Worked on a robust charting library (containing 12 different charts) using JavaScript and D3.js.

    The basic idea was to create a robust library that receives a config (or multiple configs) and data objects and creates all the requested charts based on their configurations.

    The charts were robust, independent of one another, you could update their data, and see it in real-time with cool animations. The charts were also responsive for different screen sizes.

  • Shopify | ERP Bridge Application (Development)

    Developed a REST API back-end service used for synchronization of data between a webshop and an old legacy ERP system. It registered domains for deployment servers, set up Docker containers, used Docker-Compose for integration of Docker containers, set up Nginx, set up SSL certificates on Nginx, and automated deployment using Bitbucket pipelines.

    Technology stack was Django-Python, PostgreSQL, Docker, Docker-Compose, Bitbucket Pipelines, Nginx, Gunicorn, Redis, Celery, JavaScript, jQuery, Shopify (Liquid and Shopify Webhooks)

  • The Comprehensive Guide to JavaScript Design Patterns (Publication)
    As a good JavaScript developer, you strive to write clean, healthy, and maintainable code. While you solve interesting and unique challenges, you’ve likely found that you’re often writing code that looks similar to the code for an entirely different problem you’ve handled before. You may not know it, but you’ve used a design pattern.
