Summary
👤
SeniorDonald Viszneki is a Senior Software Engineer with 17 years of experience building systems from embedded firmware to web servers, GUI libraries, and cloud infrastructure. Based in Las Vegas, he blends deep systems expertise—15+ years on Linux, assembly across ISAs, and database and concurrency work—with prolific full-stack development in languages like C, C++, D, Python, and modern JavaScript. He has a track record of simplifying complex codebases (once reducing 700+ lines to seven) and modernizing legacy platforms while leading teams and managing OpenStack, Ceph, and dozens of production servers. A frequent open-source contributor, he improved the DlangUI cross-platform GUI by adding OpenGL context sharing and modern graphics primitives like VBOs/VAOs, and he works on SpiderMonkey-related tooling. Didactic by nature, he enjoys mentoring and creating reusable middleware, frameworks, and developer tools as much as end-user applications. He’s seeking a collaborative team where his wide-ranging systems and transformation skills can drive both product and engineering growth.
