ABOUT ME

Senior software engineer specializing in diverse technologies

I am a senior software engineer with 14 years of experience in developing scalable, high-performance solutions. My expertise spans multiple programming languages and technologies, with a strong focus on Nix-based development, functional programming, and systems integration. I have a proven track record in leading projects that improve workflow efficiency and reliability, particularly in environments utilizing advanced Linux tooling and cross-compilation. My work includes designing and maintaining complex applications, from CAD routines for civil engineering to 3D drill hole design solutions for mining. Additionally, I am experienced in building robust integrations for business systems, crafting APIs, and creating automation solutions for enhanced data accessibility. Skilled in collaboration, I also mentor teams on best practices and code quality, fostering a high standard in every project.
