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 offer end-to-end solutions, including CI/CD pipelines, containerization, packaging at both Python (wheel) and Linux (deb) levels, and deployment to cloud infrastructures.
