Codethos is a gamified learning platform for developers who want to build real programming and application security skills through hands-on challenges.
Instead of toy coding exercises, Codethos focuses on production-oriented problems such as parsing, file I/O, APIs, authentication, rate limiting, access control, vulnerabilities, and other real-world engineering scenarios.
The platform combines structured learning paths, automated grading, XP, streaks, leaderboards, achievements, and verifiable certificates.
Codethos currently offers tracks in Programming, Application Security, and Bioinformatics, with exercises designed to help learners understand, build, debug, and secure real software.
It is particularly useful for developers who increasingly rely on AI coding tools and want to develop the skills needed to understand, review, debug, and secure generated code.

Don't do bootcamp. Start with something like https://freecodecamp.org and take a few lessons. Try to build something from that and see how motivated you are. If you see some progress and this thing still excites you, then may be find an engineer (a friend/co worker etc) who can guide you a bit as you continue to build something. Start small and stay away from bootcamps (my 2 cents). - Source: Hacker News / over 2 years ago
