Welcome

Hi, I'm Krzysztof, but feel free to call me Chris. I'm a full-stack developer with a strong focus on teamwork and code quality.

I'm passionate about problem-solving and enjoy crafting efficient backend and frontend solutions.

I'm focusing on Python, React, .NET, C#, MAUI, SQL databases, and RAG with LLM models to rapidly develop automation and educational applications.

In my development work, I am supported by Git, GitHub, Docker, Ansible, VPS and Raspberry Pi.

Gym Manager

Application

gym manager

A comprehensive gym management application. The codebase is organized around Onion Architecture. The application is built on ASP.NET Core 6 MVC, and some elements also use ASP.NET Core 6 Web API. Advanced features include payment processing, PDF generation, request logging, and application performance monitoring.

Main Application Areas

  1. New Features in the Application
    • Full CRUD implementation with soft delete
    • Globalization - Language change in interface
    • Sorting, filtering, pagination of displayed data
    • Displaying deleted data (soft delete)
    • Usage of ASP.NET Core 6 Web API for certain application elements
    • User action logging
    • Application performance monitoring
    • Global exception handling
    • Middleware
    • Email sending
    • PDF generation
    • Payment handling on test API
    • Client Dashboard statistics and graphs
    • File uploads to server
    • Calendar module
    • Generating passes in QR code format"
  2. Expanding Features in the Application
    • Utilization of all elements from Main Project
    • More elaborate frontend, separate template for application and admin module
    • Detailed unit and integration tests
    • Advanced Authentication and Authorization

Service Radar

Application

The project was built on ASP.NET Core 7 MVC. My main focus was on the Backend and learning key elements of modern applications. I utilized a standard Frontend template with minor color modifications. I also added a Floating Action Button (FAB), and a connected modal window displays crucial information needed for testing the application.

Main Application Areas

  1. Architecture and Design Patterns
    • Project Structure (Onion Architecture)
    • Design Patterns (MVC, CQRS, CRUD, SOLID, DTO, DAO, ViewModel)
    • Dependency Injection, Extension Methods
  2. Security and Access
    • Authentication & Authorization using ASP.NET Core Identity
    • Resource Authorization Mechanisms (Roles and Claims)
  3. Testing
    • Unit Testing - tools: xUnit, Moq
    • Integration Testing - tools: xUnit, Moq
  4. Deployment and Hosting
    • Production version of the application online on .NET hosting
    • Purchase and configuration of domain and subdomain
  5. Development Tools
    • Visual Studio 2022
    • SQL Server Management Studio 19
    • Git and GitHub
  6. Project Management and Documentation
    • Full application lifecycle from concept, through planning, implementation to deployment and documentation.

Backend

  1. Programming Languages and Frameworks
    • C# v10
    • ASP.NET Core 7
    • Entity Framework Core
  2. Libraries and Tools
    • AutoMapper - Object-Object Mapping
    • MediatR - Request/Response Messaging
    • FluentValidation - Chainable Validations
    • xUnit and Moq - Unit Testing/Mocking
    • BuildWebCompiler - SCSS/JS Minification
  3. Databases
    • SQL
    • CodeFirst Approach
    • Seeding

Frontend

  1. Core Technologies
    • HTML
    • CSS (SASS)
    • JavaScript
  2. Libraries and Tools
    • Bootstrap - My Custom Module Set
    • toastr - Notifications
    • Ajax - Data Retrieval and Addition
    • Node.js - Autoprefixer, browserlist
  3. Interactions and UX/UI
    • Modal Windows
    • Floating Action Button (FAB)
    • Notifications via toastr
    • Validation (FluentValidation)
    • Responsive Template

My Other Projects

Here's a showcase of my coding adventures from WSB - National Louis University, GetAcademy and Kodehode (It utvikler AMO).

These projects, focused on understanding key coding concepts, have not only honed my programming skills but also enhanced my project planning and management abilities through time spent on documentation.
