Description

I am a software engineer specialized in designing, implementing, and modernizing backend applications in Python. I have a strong background in software architecture, with experience in microservices, REST APIs, layered architectures, and pipes & filters. This enables me to engage with a wide range of systems – from scalable web applications to high-performance computing. I have worked across diverse IT sectors – from algorithmic trading and digital marketing to energy, IoT, and embedded systems – allowing me to adapt quickly to new domains, anticipate potential challenges, and deliver tailored, efficient solutions that meet requirements. Based on my hands-on experience in DevOps, I deliver end-to-end solutions, including CI/CD pipelines, containerization, packaging at both Python (native) and Linux (deb) levels, and deployment to cloud infrastructures.

I contributed to the development of an algorithmic trading platform by implementing several automated order types. To support reuse and flexibility of trading logic, I applied the composite design pattern, enabling modular composition of order behaviors and streamlined extension of the system with new strategies. I also helped expand the code infrastructure, allowing clients to develop their own trading algorithms. Additionally, I wrote integration tests to demonstrate compliance of the delivered software with the strict regulations of energy exchanges.

I automated the maintenance and delivery of configuration files for multiple hardware variants by developing a microservice-based backend application. I implemented CRUD operations for JSON documents stored in version control and exposed them through a RESTful API for both human and machine-to-machine interactions. To ensure compliance with company-wide domain logic, I added a validation and consistency checking layer. I also configured a message broker to distribute maintenance events that triggered automated business processes.

I optimized the release process of a high-throughput messaging system by mapping and documenting the existing workflow, clarifying team responsibilities, and driving an organizational change that centralized release responsibility in a single tech team. I automated manual steps, eliminated dependencies, set up supporting tools such as deployment notifications and release planning, and streamlined delivery — reducing release effort from two weeks with ten people to just two days with one.
