As a qualified Software Developer & 3D Programmer with over 15 years of experience in the industry, I offer knowledge and proficiency in a large number of programming languages, frameworks and platforms. This includes (almost) anything from lowest-level embedded development on Linux with pure C over time-critical optimization of video encoding in AWS EC2 with Python to web-only and mobile-first frontend development in Flutter with and without 3D rendering. If it can be done via programming, I am confident that I can do it, and will do so reliably and with transparent communication.
