Coding Dojo: Hardening multi coding language kata

📅 Last week of the month (30th of April)
📍 FreshMinds office Leiden (Kern 5, 6th floor)
🕕 Walk-in from 17:30 | Start 18:00

Writing software is one thing. Making it secure is a craft.
In this Coding Dojo we take on a unique kata focused on hardening applications across multiple programming languages. This edition explores how to improve the robustness, safety and reliability of applications generated by AI - a challenge that is becoming increasingly relevant as AI plays a larger role in software development.

The challenge consists of:
• 3 coding languages
• 3 difficulty levels
• 3 final bosses
• 9 AI-generated applications

Each application contains vulnerabilities, architectural trade-offs or design decisions that invite deeper analysis. Think input validation, dependency risks, secure design principles and balancing maintainability with protection.
You will work in small groups, compare approaches and learn from different perspectives. As always, the goal is not the perfect solution, but understanding the trade-offs that shape good software.
Whether your interest lies in software design, security, architecture or simply solving interesting technical problems, this session offers challenge at every level.

🧠 What to expect:
• Hands-on security challenges
• Multiple solution strategies
• Insights into trade-offs between security, complexity and maintainability
• Learning from other developers
• Pizza, whiteboards and strong technical discussions
