Secure, maintainable, and professional code from development

What is Best practices and safe development?

Security and code quality aren't layers that are added later—they're built from design and maintained with daily practices. A team without training in secure development introduces vulnerabilities that cost much more to fix in production than in development. At Q2BSTUDIO we form teams in good engineering practices and application safety so that quality is a habit, not an exception.

The course covers two complementary axes: application security (how to write code that is not vulnerable) and engineering quality (how to write code that is maintainable, testable and deployable with confidence).

In security: OWASP Top 10 with real examples and exploitation/correction exercises, input validation, parameterized queries, authentication/session management, security headers, CORS, CSRF, secrets management (vault, environment variables, never in code), dependencies and supply chain, logging without sensitive data and principle of least privilege.

In quality: effective code review (what to look for, how to give feedback), testing with strategy (pyramid, when unitary vs integration vs e2e), secure refactoring (change without breaking), CI/CD as a safety net (lint, tests, SAST in pipeline), useful technical documentation (not bureaucracy) and technical debt management (identify, prioritize, reduce).

The exercises combine real vulnerable code analysis (CTF-lite), vulnerability fixing, pipeline configuration with security checks, and group code review with structured feedback. Participants practice on code similar to the one they write daily.

We adapt to the team's stack: JavaScript/TypeScript, Python, Java, C#, Go or other. The principles are universal; The examples and tools are adapted to the language and framework they use.

Upon completion, the team has the discretion to write secure, maintainable code, review others' code effectively, and set up pipelines that detect problems before they reach production. We deliver security checklist, code review guide and reference CI configuration.
