Work experience
Security analyst, pentester Sovcombank PJSC Jan 2021 – present
  • Currently working as penetration tester in the bank testing their external and internal information systems
  • Acting as an analyst to help developers develop secure apps
Golang software developer Sovcombank PJSC Jul 2018 – Jan 2021
  • Developed my own open source alternative to a popular UNIX utility named cntlm which uses Kerberos instead of NTLM. escobar has received a strong feedback from my colleagues and solved a long-standing problem: a lot of software doesn't even support basic proxy authorization, let alone Kerberos.
  • While working in the bank, I had a lot of experience with cryptography (e.g. one of my libraries I was able to publish on GitHub)
  • Had an interesting project which required to implement own library that used proprietary stateful binary protocol (with some reverse engineering)
  • Designed and wrote public APIs and various microservices (mostly HTTP)
  • Worked a lot with SQL (especially PostgeSQL)
  • Of course I used Docker and GiLab's CI/CD
Software developer freelancer Jan 2016 – Jul 2018
  • Mostly wrote messenger bots with various public API integrations (Telegram, Discord)
