What I'm looking for

I'm looking for opportunities to further develop my programming skills and use my mathematical and algorithmic background, building on my experience in embedded software development on Linux for mobile networks. I'm open to learning new technologies and changing my career path for interesting work.

At Nokia, I create high-level solutions for new features, define requirements and interfaces, and write code for embedded software on Linux. I’ve optimized and documented algorithms, including speeding up several widely used ones by orders of magnitude, supported critical customer issues, and developed testing methods that improved reliability and speed.

Earlier at Nokia, I planned feature implementation as a Technical Leader, led maintenance task forces, and onboarded engineers. As an Embedded SW Developer, I developed C and C++ features based on OBSAI, CPRI, and eCPRI protocols. My mathematics thesis produced a polynomial-time dynamic-programming algorithm for maximizing n-gram scores in polyalphabetic cipher decryption, implemented in Python.
