This Qt and C++-based application is optimized for live video streaming using an HP Sprout 14MPix camera with real-time image correction. The application includes a post-processing mode where users can perform additional processing such as color adjustment, rotations, object segmentation, OCR, and export captured images to various formats. Delivery included MSI and Appx installers using Omnibus and WiX toolkits with custom actions.

The WPF/DirectX application allows users to perform scans of 3D objects from various angles and merge them into a single object representing the 3D model. Scans may be captured in manual or automatic mode utilizing the HP Stage accessory and built-in edit and 3D-printing capabilities using a locally attached 3D printer or Sculpteo remote service. The delivery included an MSI installer using the WiX toolset with custom actions.

This HTML5 application for an in-vehicle infotainment system is based on the Tizen IVI build, including the home screen, dashboard, music player, store, phonebook, and navigation. The project was successfully demonstrated by Intel at CES 2013 and was later incorporated into the core Tizen SDK.

This is a .NET portal solution for wildlife, transportation, and valuables protection based on custom geolocation hardware units. The solution is based on a three-tier architecture built on an MS SQL server, a business layer using SOAP, and multiple thin clients, including a native Pocket PC client, mobile web page, and desktop mobile web using the single-page approach.

Image capture, connectivity, and interoperability capabilities for SC2000, which included communication with other development sites, requirements refinement with the customer, and delivery of the implemented functionality. The project was driven by Agile methodologies (Scrum and test-driven development) with heavy usage of inter-process and inter-thread communication using different languages (.NET <-> C++, C++ <-> C).

A static website generator with a UI written in Windows Forms, serving as an electronic shop with group hierarchy, items, filtering, and ordering. The application was packaged for delivery using an NSIS installer.

A rework of the original static site generator to a CRM-backed solution for creating eShops. The back end was written in Node.js using MongoDB and Keystone.JS as the CRM system. The front end was written using Svelte. A live version can be viewed at http://www.otoelektronik.sk/.

The Kiosk experience for HP Sprout allows one to connect the back-end office with support staff and a walk-in solution to provide real-time collaboration. The back-end solution was written using Node.js, TypeScript, MongoDB, and Redis. The Kiosk application was written using Electron and WebGL and WebRTC audio, video, and data channels were used for communication. The delivery included MSI installer using Electron Installer package and automated updates using Squirrel framework.

The content for the Sprout Marketplace was served inside the WPF WebContainer, which allows users to browse and purchase new applications on the Sprout platform. The application front end was written using React and TypeScript, and HP back-end services (HP Web Services, HP Payment Gateway, HP Catalog, and HP Download Agent) were integrated.

I migrated multiple microservices originally written in Python and Go to a .NET Core platform and developed a new client dashboard written in Blazor. All parts communicated with data sources in an MS SQL database via Entity Framework and were deployed as Docker images and optimized for speed of access.

This is a React and TypeScript onboarding and learning application for HP Sprout deployed as an Electron application with Node-API (formerly N-API) bindings. It calls for platform-specific C++ functions and integrates with the rest of the HP WorkTools suite.

A multi-browser WebGL animation for the front page of a database research project, including custom shaders showing infinitely rotating spheres with animations, TV-noise effect, and SVG logo support written using Three.js

As a fintech expert full-stack engineer, I developed multiple full-stack web-based applications for SaaS payroll software built on top of the Python Django framework with asynchronous processing via Celery and deployed them on the AWS stack. The front end was built using TypeScript, React, and multiple UI frameworks (Material UI, AntD, and Tailwind).
