I believe that opportunities for learning should be free from economic and physical limitations.
We pursue equality in opportunities for growth.

Co-instructor


A free live session 📺 for those of you hesitating
in front of the wall called 'Legacy'


In an era where AI opens up countless possibilities,
it seems our career concerns as developers
are only growing deeper.


'Legacy code', 'old tech stacks'...
Are you passing by attractive job postings
just because of these words?


Perhaps we are missing out on the best opportunities for growth due to a vague fear of legacy
.


In this live session, we are going to talk about why the 'legacy environment' that everyone wants to avoid
is actually an opportunity in the AI era.

2026. 3. 5.(Thu) 19:00 ~ 21:00

Talk Session

Centered around three main themes, an in-depth conversation and sharp insights from two senior developers, Jaemin and Hyangro, will unfold.

Q&A Session

This is a time to directly hear the experiences and thoughts of two seniors regarding all the questions you've had as a developer, such as career, legacy, and how to utilize AI.


[Topics to discuss 💬]

We will discuss three main topics together.


The First Story

How is the developer job market these days?

How do you view the current developer job market? Has everything truly changed because of AI? Or are you perhaps hesitating to apply—even though the number of job postings remains similar to before—because of conditions like 'legacy,' 'tech stack,' or 'domain'? Maybe it's because career growth seems uncertain.

Perhaps we are missing out on unexpected opportunities for growth because of that very hesitation.


The Second Story

The Inevitable Legacy Environment, and the Opportunities Created Within It

In fact, most companies around us are built upon legacy environments. On your first day of work, you've likely experienced that sense of helplessness when faced with a massive, disorganized codebase.

Surprisingly, however, true growth and opportunities are hidden within the process of digging through that chaotic legacy and carving out a path. We will prove this to you through the vivid experiences of two senior developers.


The Third Story

Practical ways to collaborate with AI

Legacy environments have always been a land of opportunity(?) in the past, but now, thanks to AI, we can experience even more limitless possibilities. This is because we can rapidly analyze vast amounts of legacy code by collaborating with AI.

Even if your company doesn't support AI tools, it's okay. I will introduce all the most practical ways to fully utilize AI's capabilities even in such an environment.
