Experience
Resource Optimization System for the Wind Industry
Developed a game-changing enterprise SaaS intelligent simulation and optimization technology for the wind power industry. Analysis is accurate and fast, capable of planning, and provides daily progress reports. It is optimized to handle a large amount of data.
Website Analytics and Tracking System
I developed a new analytical platform for the website owners. The platform enables them to understand their customers and their behavior better. The owners can replay user sessions, watch visitors in real-time, detect objects of interest, and conduct user interface analyses.
Micro-job Portal
Developed one of the biggest micro-job portals in Slovakia. The portal has more than 140,000 users. It offers thousands of services, products, and job offers. Any user can register as a seller for free and start building their online business. Buyers are protected and only pay when they are fully satisfied with the result. A variety of payment solutions are implemented offering flexibility.
Automated Website Generation from Image
Built an application and algorithms that enabled users to upload their graphical designs (e.g., in PNG format) and download an automatically generated website in HTML and CSS. The application is fully automatic and uses Computer Vision. The results are highly comparable to the work of front-end developers.
Custom E-shop System
Built a custom e-shop system for an advertising company. The products consist of multiple options, including quantity discounts. Users can use product designs directly in the web application and apply them to the products (e.g., a roll-up banner).
Task Management System
Full-stack development of an application for managing, collaborating, and organizing work. It enables users to add projects, sections, and tasks and offers both list and Kanban-style board views.
Digital Signage System
Developed a signage system and a corresponding web application. Users can manage and create the content they want to showcase on digital displays such as an LCD. The content can be as simple as an image or video, but there are also advanced options such as a product slider or Instagram feed. The application also enables custom scheduling of selected content or real-time controlling.
HR System
Built and tested a B2B web application system for an HR client. The system enabled customer, employee, group, and advanced calendar management, vacation planning, and several other functions.
Residence and Citizenship Portal
I created a new version of the website for a global company providing residence and citizenship solutions. The page content was separated into components and the portal offers different kinds of programs for its potential investors.
MMO Game
Designed and developed a massive multi-player online real-time game. The game consists of essential components such as a map, blocks, bombs, players, and abilities. Players can join the game, move around the map, fight against each other using bombs, chat, and improve their skills.
Travel Related Quiz Game
I built a travel-related game using an external public API. The game falls into a quiz category and contains six different types of questions generated randomly. Each player has a limited number of lives and a time limit to answer. The purpose of the game is to gain the highest score by answering questions correctly. It also contains music, global leaderboards, and user settings.
