Welcome
My name is Damian, and I am a computer engineer working as a software developer. I am interested for IT, Applications development and everything related to modern technology that makes our world easier and more efficient. My homeland is Poland. I like going to the gym and jogging outdoors. I am interested in new places, cultures and art.
Passion for Programming
Programming and process automation have been the main direction of my professional development for many years. I began my career working with control systems and CNC machine programming, but over time I decided to expand my skills and move into modern software development. I focused on developing web and backend applications using technologies such as C#, ASP.NET, Blazor, JavaScript, HTML and CSS. I continue to grow in API design, SQL database work and building applications running in server and cloud environments. At the same time, I gained experience in Linux server configuration and maintenance, application deployment, domain and certificate. Currently, I am further developing skills in DevOps practices, deployment automation, containerization and integration of AI-based solutions. My goal is to build modern applications and services that genuinely support users and companies in process automation and digital transformation.
My Future
As a programmer, I look forward to a calm, secure, and stable future. The work I do at the computer gives me great satisfaction and fully engages me. I truly enjoy new challenges and the sense of accomplishment that comes with achieving goals. Tasks entrusted to me are carried out consistently, together with trusted colleagues and leaders who believe in shared success. I believe that over the next 15 years, I will continue to grow as a full-stack developer, learning new languages and continuously exploring modern programming technologies.
My Skills and Professional Focus
Below you can find the main areas of my current professional development and work, with a strong focus on .NET development, application architecture, DevOps practices, cloud environments and modern frontend technologies. My goal is not only to build working software, but solutions that are maintainable, scalable and production-ready..NET / ASP.NET Core / Blazor / Web API
My main professional focus is building applications within the .NET ecosystem. I develop backend systems and web applications using ASP.NET Core, design and implement REST APIs, and build user interfaces with Blazor (Server and WebAssembly) and Razor Pages. I pay attention to practical aspects such as API contract design, validation, error handling, logging, performance, and application security. I value solutions that are predictable, easy to extend and ready to be developed further by teams using modern CI/CD processes.
Application Architecture & Design Patterns
I design applications with strong attention to architecture quality, modularity and long-term maintainability. I work with approaches such as Clean Architecture, layered design (Domain / Application / Infrastructure), and apply SOLID and common design patterns where they provide real value. In practice this means clear responsibility boundaries, minimal coupling, predictable data flow and code that remains understandable and extendable even months later. My goal is always to create solutions that teams can safely evolve over time.
DevOps / Docker / CI/CD / Azure DevOps
I enjoy the phase where applications move from development environments into stable production deployment. I use Docker to containerize services and dependencies and configure CI/CD pipelines using Azure DevOps for automated build, testing and deployment processes. Working in Scrum teams, I understand the importance of transparent workflows, pull requests, code reviews and automated quality checks. For me DevOps means repeatable environments, predictable deployments, quick rollback options and reliable operational processes.
Cloud & Infrastructure (Azure / VPS / Hosting)
I deploy and maintain applications in production environments, including domain configuration, DNS setup, SSL certificates, reverse proxy configuration and server security. I have hands-on experience managing Linux Ubuntu VPS servers for hosting .NET applications, diagnosing environment issues and maintaining reliable uptime. At the same time, I continue expanding my knowledge of cloud services such as Azure and understand differences between self-hosted infrastructure and managed cloud solutions. My priority is predictable, secure and maintainable deployments.
Frontend: Angular / React / TypeScript
I develop modern frontend applications using Angular and React with TypeScript, focusing on maintainable project structure and predictable application behavior. I enjoy connecting strong backend APIs with responsive and user-friendly interfaces, including proper state management, form validation and efficient component organization. For me, frontend development is not just visual work but an integral part of a product, influencing performance, usability and overall user experience.
Databases: SQL, Redis, MongoDB
I work with relational databases such as MS SQL as well as NoSQL solutions like MongoDB, and use Redis caching where performance improvements are required. I understand the importance of correct schema design, indexing strategies and query performance, and how database design affects application scalability. My interest covers the full data flow in applications, from domain modeling and migrations to performance monitoring and troubleshooting production issues.
Communication: REST, WebSocket, SignalR & Integrations
I build and integrate systems using APIs and real-time communication technologies. My work includes REST API design, versioning, validation, and error handling, as well as real-time features implemented with WebSocket and SignalR. I value stable integrations with clear data formats, predictable error behavior, and systems that are easy to debug and extend. This allows applications and services to work together as reliable and scalable systems.
Desktop & Mobile: .NET MAUI / WPF
I build desktop and mobile applications using .NET MAUI and WPF, connecting them with backend services and APIs. My focus includes MVVM architecture, clean view models, responsive UI, hardware integrations and service communication. I enjoy projects where client applications are real tools rather than demos, stable in daily use and designed for future expansion.
AI Integration & Automation
I integrate AI capabilities into applications where they genuinely improve workflows and user productivity. My interest lies in practical usage: controlling costs, validating outputs, logging interactions and ensuring predictable system behavior. I also use AI tools to accelerate software development processes, automate repetitive tasks and prototype solutions faster while maintaining code quality.
Team Work: Scrum & Azure DevOps Workflow
I work comfortably within Scrum environments, understanding sprint planning, backlog prioritization and iterative delivery. Using Azure DevOps, I manage tasks, repositories and development workflows including branching strategies, pull requests and code reviews. I value transparent teamwork, well-described tasks and incremental delivery that continuously improves software quality.
Languages: German & English
I work comfortably in both German and English technical environments. Having spent many years working in Germany, I am familiar with professional communication in international teams, both technically and organizationally. This allows smoother collaboration, clearer documentation handling and efficient participation in distributed teams.
Technologies I Started With (Foundation)
My programming journey started with PHP, jQuery and classic JavaScript, building early web applications and learning HTTP-based communication in practice. These technologies gave me a strong foundation in frontend-backend cooperation and rapid prototyping. Over time I naturally transitioned toward modern .NET ecosystems, architecture-driven development and cloud-based solutions, but this early experience still helps me understand problems and find effective solutions quickly.
