People of PnT: Building Real Impact Through Frontend

In this month’s edition of People of PnT, we sat down with Sujin Park, our talented frontend developer, to learn more about her journey, daily work, and thoughts on what it takes to thrive in a cross-functional tech team. From real-time UI challenges to collaboration tips, here’s a closer look at life behind the screens.

Q: What sparked your interest in frontend development, and how did you end up joining People and Technology?

A: I naturally became interested in frontend development because I found it fascinating and fun to see how the web responds instantly. As I continued studying, I became more drawn to systems that handle real data and change behavior depending on different situations, rather than just static web pages.

When I saw People and Technology’s real-time location tracking and monitoring systems, I thought, “This is something that’s actually used on-site.” I was attracted to the idea of creating features that people genuinely need, not just things that look good on screen. That’s what made me want to apply.

Q: What does a typical day look like for you as a frontend developer?

A: In the morning, I usually start by reviewing what I worked on the day before and handling light code reviews or meetings. After that, I focus on developing and testing assigned features.

Throughout the day, I stay in constant communication with designers, planners, and backend developers to address any issues related to how the screens work or how things are integrated. Before I finish for the day, I check pull requests and clean up my code.

Q: You collaborate with many teams like design, backend, and planning. What do you pay attention to for smooth collaboration?

A: When I receive a requirement, I don’t jump into coding right away. I first try to understand the purpose and context. I aim to figure out what problem the planner or designer is really trying to solve, and then suggest a feasible implementation plan.

With backend developers, I try to reduce confusion by documenting or aligning on things like API specifications and response structures.

Q: What do you think is the most important skill for a frontend developer?

A: I think communication and collaboration skills are the most important. Frontend developers don’t just write code; we also need to align with planners, designers, and backend developers, and often explain screen behavior or issues to non-developers.

Aside from that, the ability to think structurally is crucial. Even when building a single screen, it’s important to stay aware of its role within the overall system and approach it with that in mind.

Q: Can you share a recent moment when you felt you had grown as a developer?

A: In the past, I struggled with complex logic or tricky type issues. But recently, I’ve been able to manage asynchronous flows, separate conditions, and narrow down types on my own, and that’s made me feel like “I’m really starting to get it.”

I especially felt growth when I saw clear improvements after refactoring real-time UI updates using sockets or solving performance issues.

Thank you Sujin for taking the stage of this month's edition :)

Stay tuned for next month’s People of PnT interview, where we’ll introduce another member of our team and share more stories from behind the scenes at People and Technology. See you then! ✨
