haechandevThis is not a list of credentials. It is a line of what I have learned, the problems I choose, and the businesses I want to build.
2020
In a high school club, I first met C and Arduino. Building servo controls, simple robot interactions, serial commands, and a humidity-controlled smart farm showed me that code could create movement in the real world.
2022
I entered Ajou University’s Department of Software in 2022. Starting again with Bronze Baekjoon problems, I studied C and algorithms intensely and reached Gold 3 in about six months.
2023
Meeting a friend doing client work shifted my focus from passing a problem to building programs people actually run and use. My first Flutter work connected screens, authentication, data, and a user’s next action into one product flow.
2024
Supporting information and communications systems taught me that reliable operations begin with small checks and precise procedures. I improved how essential status was surfaced and considered both security and day-to-day usability in recurring access management.
2025
Interactive kiosks taught me that a product is completed by real people, real devices, client expectations, and the constraints around them.
2026
Building products made me consider user flow, operating cost, value, revenue structure, and the limits of an AI feature together.
Now
I am building tools that keep evidence, decisions, and unanswered questions so people and teams can make clearer next choices.
Ahead
I do not know every field, business, or product I will meet next. I do know that learning does not end, and that I will keep looking for better questions, creating value people need, and moving forward.
I do not want to stop at building technology.
I want to understand problems, give people a reason to choose a product, and think through the structure that lets it last.
