About

I have a strong character and determination in pursuing global standards and security awareness in distributed information processing. With a solid understanding of leading cloud provider technologies and CI/CD processes, I am well-versed in the tools and utilities required to operate, test, debug, and run risk assessments in modern IT systems, particularly in the software as a service sector. My hands-on experience encompasses site reliability engineering, system administration, research and development, and security operations of bare-metal, virtualized, and containerized Linux-based distributed systems using languages such as Golang, Java, Ruby, .NET, Python, Node.js, and PHP. Notably, I have documented practice in versioning, maintaining changes, and managing releases for an OSS project federated with the Polish government, deployed on the Google Cloud Platform. In my career, I have overseen over a million service level indicators in large production cloud deployments, managed more than a hundred thousand successful pipelines and workflows on both private and public repositories, and executed over ten thousand production deployments to cloud environments. I have kept over a thousand client git repositories up-to-date, contributed to the satisfaction of over 500 developers and engineers, and amassed more than 15 years of software maintenance experience. Additionally, my professional journey includes a five-year career in handball, earning a gold medal at the IHF World Championship. My interests span basketball, connectomics, consciousness, open-source software, user flow automation, source version control, continuous integration, decentralized RPC protocols, OS and hardware virtualization, natural language processing, machine learning algorithms, post-quantum cryptography, deep learning, and computer vision.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
