Personal

I'm a software engineering specialist driven by curiosity and a will to expand and improve my knowledge and skills. I've been interested in computers since I was 8 years old and I've been programming almost from the start always learning and exploring new things. In my professional career and in my free time I've explored many different aspects of software engineering including design of huge systems, low level hardware programming, graphics interfaces, memory management systems, file systems, networking, operating system design and implementation, programming language implementation, etc. I've used all different sorts of programming languages and paradigms including imperative, object oriented, functional and logic languages. I'm confident that there is nothing in the software engineering field that I can't learn in a short time and master faster than others.

Recently I've been also working with mangement of software projects primarily focusing on ensuring the quality of the resulting work.

Qualifications summary

  • Main focus: operating system design and implementation, memory management, file systems. C, Unix, BSD, kernel.
  • Experienced in a wide range of programming languages and libraries. Quickly learning new languages and libraries.
  • Experienced in using and administering various operating systems.
  • Experienced in systems security, mainly in making software more robust, but also in cryptography and network security.
  • Extremely focused on writing high quality code and ensuring that other don't slip which could lead to bugs.
  • Experienced in leading the work of software developers, mainly to improve the quality of their output.
  • Very experienced in debugging all kinds of software problems, both with and without aid of various tools.
  • Good understanding of licensing, patents and other legal issues around software.
