I’m a Software Engineer with over 5 years of hands-on experience building and shipping software — from business automation tools to commercial games and data-driven dashboards.
Over the years, I’ve worked on diverse projects spanning a wide range of languages and technologies, equipping me with a strong grasp of core programming principles, design patterns, and the art of delivering robust, efficient solutions.
Since August 2023, I’ve worked as the first in-house Software Developer at Lehmann Elektro, leading full-stack projects and designing robust backend architectures. Managing deadlines, architecture decisions, priorities, and other project management tasks has helped me grow not only as a Software Developer but also as a de facto Project Lead.
My focus: clean, efficient, production-ready systems.
I enjoy backend-heavy development where architecture, logic, and speed matter.
