 Ruby – dynamic language, build for simplicity and productivity
(mostly for back-end Web apps, alternative to PHP and Python)
 C – language for system programming and low-level
development (for embedded and kernel-level devs)

How to Become a
Software Engineer?

 First find out if programming is for you!
 Sign up for the SoftUni free coding
course for beginners: https://softuni.bg
 Or follow a tutorial / book / video course on the Internet
 Does programming excite you?
 Do you really like it and enjoy it?
 Are you good at coding problems?
 Do you want to write code all the time?
How do I Become a Software Engineer?
25

 To become a software engineer, you
need to study hard and consistently!
 1-2 years @ part time (15-20 hours / week)
 Or 1 year @ 8-10 hours daily
 Developing practical projects
 Write ~ 100K+ lines of code (LOC)
 ~ 100K LOC == 300 days * 350 LOC
Study Hard with a Lot of Practice
26

 4 main groups of dev skills:
 Coding skills – 20%
 Algorithmic thinking – 30%
 Fundamental software
development concepts – 25%
 Programming languages and
software technologies – 25%
