Are we looking at software engineering the wrong way?
What if it’s less about writing code and more about making better decisions in an ever-changing system?

Learn a revolutionary approach to understanding complex software systems in my conversation with Tudor Girba, the CEO of feenk. We explore “Moldable Development,” a groundbreaking concept that challenges traditional views of software engineering. Learn why treating development as a decision-making process, supported by custom tools, is crucial for tackling today’s software challenges, especially when dealing with legacy systems.

Key topics discussed:

  • Software Engineering as Decision-Making: Why software development is fundamentally about making informed decisions rather than just constructing systems.
  • The Inefficiency of Reading Code: Developers spend over 50% of their time reading code, yet this activity remains unoptimized.
  • Moldable Development: Learn how creating custom tools tailored to specific problems can revolutionize your workflow and decision-making process.
  • Legacy Systems as Opportunities: Reframe legacy systems as value-creation opportunities instead of burdens.
  • Glamorous Toolkit: Discover the innovative development environment enabling thousands of micro-tools for better system understanding.
  • The Future of Development Environments: Explore how AI, moldable development, and tools like Glamorous Toolkit can coexist to solve diverse class of problems.

This conversation will completely transform how you think about software development!
