My name is Damian Czajkowski, a passionate Software Engineer from Białystok, Poland. I specialize in Python development, with experience in AWS, serverless architectures, and cloud-native applications. I have a strong foundation in problem-solving, honed through competitive programming and a transition from C++ to Python. My goal is to build efficient, scalable systems while adhering to best practices like SOLID principles and design patterns.
I am a perfectionist – I pay attention to every detail to deliver the best possible code that not only meets but exceeds expectations. I believe that the key to success lies in collaboration – I involve my clients in the development process, so together, we can create the best possible solutions tailored to their individual needs.
I work daily on advanced solutions based on asynchronous Python, microservices, and integration with external systems. I have completed projects related to payment systems integration, tax handling, and mail services. By working with the latest technologies, I am able to deliver stable, scalable, and secure applications.

At Mirumee Software, I focus on building serverless systems using AWS technologies such as Lambda, DynamoDB, and SQS. I lead technology meetings, contribute to open-source projects (like Ariadne Codegen and Lambda), and provide technical support to project teams. I also implemented Terraform-based infrastructure for efficient and repeatable deployments and automated CI/CD pipelines.
