I've contributed to an application with a dynamic user interface built using ReactJS. The backend, structured around the Aspect-Oriented Programming paradigm alongside MediatR, enabled seamless communication with SalesForce and various remote services. The application was crafted to efficiently handle client contracts, special offers, and associated documents. I had the opportunity to be a speaker for presentations on Microfrontends and the effective application of mocks in unit tests.

I've participated in a pioneering project developing an application simulating the glaze painting technique. The application utilized WebGL, Shaders, JavaScript, and measurements provided by the University of Białystok. The backend was implemented in .NET ASP. Collaborated with ZeroNorth, based in Denmark, to design, develop, and maintain ReactJS and ASP.NET applications within the maritime transport domain.

I've contributed to the Mediporta initiative: Crafting medical software tailored for clinics. The application, written with ASP.NET, ReactJS, and Knockout.js, has been developed to meet the unique needs of medical environments. I played a key role in creating a model testing framework using reflection in C#, where I also led the effort in refining and optimizing tests to enhance their efficiency and reliability. My responsibilities included the development and maintenance of both the backend and frontend components

I've engineered an application that strongly relies on Regex, written with .Net and WPF, employing recurring document templates for the automatic creation of summaries from invoices or flight confirmations.

I've developed a robust web application, written with ASP and .NET, for aggregating and managing transactions from over 11 affiliate networks. The application seamlessly communicates with these networks through REST, WCF, and GraphQL protocols.

I crafted a bespoke WordPress theme for the startup 'HelloData – Crowd Tracking System,' developed by Exa-Informatics. In parallel, designed the logo and web layout for the 'HelloData – Crowd Tracking System

I developed a unique WordPress theme for a family clinic.

I designed and implemented the WordPress theme for the official Polish distributor of 'Feg' products.

CheckPromo encompasses three projects: an affiliate network offer downloader, a transaction manager for affiliate networks, and a static HTML generator written in JavaScript. The HTML generator is optimized for both SEO and speed.

MicroFusion: A versatile utility set streamlining web application and microservices development. It efficiently addresses common infrastructural concerns like routing, tracing, and metrics, supporting Domain-Driven Design and Design by Contract principles. With a consistent abstraction layer, MicroFusion seamlessly integrates with tools like Jaeger and Prometheus, making robust, scalable application development more straightforward.

A library for expressing side effects by creating a contract for beginning value (arguments). This technique can be referred to as 'design by contract' or 'defensive programming.' The Suckless Assert is much faster and simpler than other similar libraries that support a fluent API and can get a field/property name by the lambda expression.

An advanced implementation of 'Maybe' and 'Either' monads for C#, enriched with extra utilities, extensions, and integrations. The main objective behind developing this library was to provide a clean and declarative interface.
