Motivated software engineer with mathematical (alghorithmic) background and information security experience (cryptography). Some achievements: - Contribution to Themis (cryptographic library); - Contribution to Acra (SQL database protection suite); - Contribution to BouncyCastle (cryptographic library); - Developing software for testing cryptographic algorithms and protocols; - Carrying out public examinations of SafeNet Luna HSM / HP Atalla HSM / IronKey flash drives that involve PKCS#11 usage; - Scientific papers co-author; - Implementing software for formal mathematical algorithms evaluation; - Developing software for testing cryptographic algorithms and protocols; - Teaching applied cryptography disciplines in the higher education system; - Security conferences presenter. Since 2012, I deal with all that is related to cryptography. It includes different public examinations of cryptographic algorithms and protocols and their implementations in hardware and software systems (cryptographic libraries - OpenSSL, BouncyCastle, etc.; Certification Authorities, hardware secure modules, and so on). I believe that cryptography makes our insecure world much more safe and friendly! I would welcome the opportunity to discuss my background in greater detail and look forward to hearing from you.
