Software Engineer

About me

Hello! I'm Mateusz, a seasoned software engineer passionate about crafting innovative solutions. With over eight years of experience in software development, I've journeyed from the trenches of .NET and Angular development to the leadership role of an Engineering Manager.

Throughout my professional journey, I've had the privilege of contributing to many projects, each one a unique opportunity to flex my technical muscles and deliver high-quality solutions.

One of my true passions is the practice of Domain Driven Design, a methodology that empowers me to create elegant, maintainable, and scalable software architectures. It's this blend of technical know-how and a commitment to best practices that drives me to continuously push the boundaries of what's possible in the world of software engineering.

Mytechnologystack

.NET

As a software engineer, my expertise lies in C#, my primary programming language.

In web development, I excel in ASP.NET Core and ASP.NET Core MVC.

My architectural and design skills extend to Microservices and Domain Driven Design (DDD), with a focus on Command Query Responsibility Segregation (CQRS).

I leverage technologies like Entity Framework, Dapper, and StackExchange.Redis for efficient database access.

In testing and quality assurance, I employ xUnit for unit testing, Benchmark.NET for performance analysis, and FluentAssertions and FluentValidation for expressive and robust validation.

To enhance resilience and reliability, I utilize Polly for fault tolerance. 

Angular

In frontend development, I specialize in crafting engaging user interfaces using Angular, which is the foundation for creating dynamic and responsive web applications.

I have a strong grasp of HTML and CSS, ensuring seamless integration of design and functionality. TypeScript is my preferred language for enhancing code quality and maintainability, while Redux and NGRX enable me to manage application state effectively.

I'm well-versed in working with Monorepo structures and NxWorkspace, streamlining development workflows. Additionally, I leverage Angular Material and Angular Elements to build reusable components and perform unit testing using Jasmine.

For design and prototyping, I utilize Adobe XD to bring user-centric designs to life.

Databases

In terms of data storage, I possess extensive experience in managing various database systems.

I excel in working with relational databases such as MS SQL, MySQL, PostgreSQL, SQLite, and Oracle, ensuring efficient data organization and retrieval.

Additionally, I'm well-versed in NoSQL databases like MongoDB and Redis, enabling me to handle diverse data storage needs effectively.

My expertise in these systems allows for robust data management and seamless integration into web applications.

Docker

I employ Docker as a critical tool in my development workflow in DevOps and containerization.

I craft efficient Dockerfiles using best practices, such as careful layers planning, installing dependencies without caching, and utilizing the lightweight Alpine Linux distribution whenever feasible.

Additionally, I optimize Dockerfiles with multi-stage builds to ensure lean and efficient container images. I also specialize in publishing .NET applications as platform-specific containers, enhancing compatibility and performance.

Docker serves as my primary environment for CI/CD pipelines, enabling seamless automation of deployment processes.

Furthermore, I leverage Docker for integration testing, ensuring consistent and reliable application performance across various environments.

Kubernetes

In Kubernetes orchestration, I demonstrate proficiency in creating and managing clusters using platforms like AKS (Azure Kubernetes Service), EKS (Amazon Elastic Kubernetes Service), and Kubeadm.

I implement essential features such as Liveness, Readiness, and Startup Probes and define CPU and memory limits for resource allocation.

I use cert-manager, which is seamlessly integrated with the Ingress controller. This integration is configured to work with ACME Certificate Authorities. It is complemented by Azure DNS or Route 53 to enable the automatic DNS01 ACME challenge.

I employ Helm charts to streamline deployment and management, ensuring consistency and efficiency in complex environments.

Furthermore, I possess a deep understanding of Kubernetes architecture, encompassing control planes and worker nodes, and I implement autoscaling and load-balancing strategies to optimize application performance.

Git

In my Git repositories, I employ best practices to maintain an organized and efficient codebase. I utilize a mono repo structure and Git submodules for modular code management.

My repositories encompass not only application code but also infrastructure components.

I'm proficient in Git platforms like GitHub and GitLab, where I practice effective version control and collaboration.

Pull Requests are a vital part of my workflow, ensuring code quality and collaboration when working within a team. This approach extends to application code and infrastructure configurations, creating a seamless and reliable development environment.

{Mateusz, pracujemy wspólnie od ponad 12 miesięcy. Jesteś najlepszym team leaderem z jakim przyszło mi współpracować. - Masz dużą wiedzę, którą się dzielisz. - Rozumiesz procesy biznesowe oraz to jak nasze zmiany na nie wpływają. - Cechuje Cię duża dojrzałość - wszystkie decyzje jakie podejmujesz są przemyślane i uwzględniają wszystkie aspekty (techniczne, biznesowe oraz ludzkie). - Aktywnie proponujesz rozwiązania i usprawnienia. - Z mojej perspektywy implementacja zmian wynikających z Antylichwy (które w sposób krytyczny wpłynęły na procesy Allegro Pay) nie odbyłaby się tak bezproblemowo i bezstresowo bez Twojego udziału. Aktywnie uczestniczyłeś i prowadziłeś analizy i działania tak aby zapewnić nie dość, że terminowe to najlepsze z możliwych rozwiązań. Czego skutkiem jest proces działający bez błędów oraz nie wpływający negatywnie na nasze wyniki biznesowe. - Świetnie prowadzisz i zarządzasz zespołem, wszystkie spotkania z Wami i Tobą są efektywne oraz w super atmosferze. Jest na nich przestrzeń do rozmowy, zgłaszania zastrzeżeń i pomysłów. Czuć, że każdy jest sznaowany i jego zdanie się liczy

{Uważam, że jesteś dojrzałym liderem i wzorem do naśladowania jeśli chodzi o umiejętności przywódcze. Znasz mocne strony każdego z członków zespołu i pracujesz nad tym aby je rozwijać np. przez dawanie im odpowiedzialności za prowadzenie inicjatyw. Wiesz kiedy należy wskazać drogę, motywować oraz podejmujesz trudne decyzje kiedy wymaga tego sytuacja, dzięki czemu wyzwania które stoją przed zespołem: - braki osobowe; - praca manualna; - konieczność tworzenia MVP i często godzenia się na dług techniczny; są zaopiekowane i pozwoliło to na zrealizowanie naszych planów w zakresie compliance i dowiezienie takich projektów jak: - antylichwa - zbieranie brakujących danych - synchronizacja danych - przygotowanie do wdrożenia DSA Bardzo cenię sobie nasze spotkania, ponieważ dają mi poszerzoną perspektywę, a także pozwalają mi uczyć się od Ciebie nowych sposobów rozwiązywania problemów. Jesteś proaktywny w szukaniu usprawnień pracy zespołu, sukcesywnie wdrażasz zmiany jak m.in. trzymanie się capacity na sprint, dbanie o DoR i DoD, czy propozycja kategorii "wrzutki" aby oceniać wpływ zadań spoza backlogu, co pozwala na coraz lepsze planowanie pracy i trafniejsze estymaty, a to przekłada się na realne podejście do roadmap. Nasza wspólna praca nad organizacją backlogu pozwala na bardziej całościowe podejście do rozwoju naszych produktów. Wiem, że mogę polegać na Twojej wiedzy domenowej, a Twoje propozycje w zakresie rozwiązań technicznych czy infrastrukturalnych są przemyślane i trafne, co widać również po tym jak duży masz autorytet w zespole.
