Prologue I’d prepared for this talk as a natural extension of the work I do every day, so I didn’t expect to be particularly nervous. But when I saw the list of other presenters ahead of time, I found myself wanting to do justice to the occasion — to make sure my talk held its own alongside theirs. Event poster — AI Accessibility Seminar: Accessibility for All. Date: Thursday, April 23, 2026, 10:00 AM – 12:20 PM. Venue: NIA Seoul Office, Basement Conference Room. Hosted by: Digital Accessibility Standardization Forum. Organized by: Universal Design Society. Event poster So I put together clean slides, wrote out a full script, ran through a few rehearsals — and headed to Seoul. The trip from Daegu isn’t exactly short, but I was in good spirits. There’s something about being needed, about being put to use, that makes you feel alive. ...

This post is part of an ongoing effort to monitor public websites as a web accessibility professional. It is written with the goal of improving information accessibility and advancing technology — not as a political statement. I only recently found out the Cheong Wa Dae website had been redesigned. Life gets busy, and I was a bit late to the news — but as soon as I heard, I was curious enough to check it out. ...

Every year, April 20 is Disability Day in Korea. I’ve been working on web accessibility at a university since 2010, but honestly, I never made a point of marking this day. I’d catch news about events held under the banner of Disability Day, but my own work felt like something that lived inside a monitor — far removed from those in-person gatherings. Then this year, on that very day, I received Korea’s Minister of Education Commendation. ...

This essay records what I have wrestled with on the ground about web accessibility, public web services, and the responsibilities of developers. Between law and technology, standards and reality, I try to answer the question: “Are we truly building for everyone?” Is today’s Seollal(Korean Lunar New Year) really providing equal information to everyone? Produced by: Nano Banana Ahead of the Seollal(Korean Lunar New Year) holiday, I browse the web to find helpful information. Seollal(Korean Lunar New Year) is a uniquely Korean holiday. As I visit site after site, the first thing I often encounter is an auto-rotating banner or card news. Around Seollal, these banners include important government notices like emergency information. ...

Since I started this blog, I have written in several directions. The areas I keep digging into are web accessibility and frontend. I want to write more, and new ideas keep coming, but the speed of writing is not as fast as I hope. Right now I still have eight unfinished drafts. Starting is easy, but wrapping up always feels surprisingly hard. AI has made research and organization much faster, but my time and energy are still limited, so it often feels frustrating. I work during the day, and after work I take care of family responsibilities, side projects, this blog, and certification prep. Honestly, I wish I had ten bodies. ^^;; Still, I want to keep going, so today I am writing a candid note about how I approach blog writing. ...

Introduction I just returned from the AI Agent Scenario Competition Citizen Evaluation Panel held in Seoul. The panel consisted of expert judges and citizen evaluators, with the final scores reflecting both expert evaluation and citizen evaluation. Since the evaluation details are confidential, I can’t discuss individual teams or specific results. However, through this experience, I was able to clearly define what standards I use when evaluating AI public services. So in this post, rather than “how this team performed,” I want to record what questions I asked and why I thought those questions mattered. ...

Introduction Let me be honest — this choice is a losing deal on paper. I’m spending a whole day, paying for transportation out of my own pocket, and the compensation is only about $35 (50,000 KRW). Yet, I’m heading to Seoul tomorrow. I wanted to organize my reasons step by step. View from a train window - a journey to somewhere Photo: Dieter K / Unsplash The Evaluation Panel Offer and My Decision One day, while browsing the NIA (National Information Society Agency) website as usual, I discovered the Public Institution Website Citizen Evaluation Panel. Since then, I’ve been grateful to participate in the public web/app citizen evaluation activities for two years straight. The rewards and achievements may seem small, but the process and experience have been building up as personal assets. ...

🚀 Starting a New Blog Hello. This is a space where I record what I learn and experience, hoping it might be of some small help to someone. I call myself a “perpetual beginner developer.” There’s always so much to learn, and sometimes I repeat small mistakes, but recording and sharing this process is both my way of growing and my joy. Why Did I Start This Blog? When developing, you encounter countless trials and errors. Sometimes you panic at error messages you’ve never seen before, and sometimes you face the same problem again today that you solved yesterday. ...
