Programs
Active study groups and projects. Study groups run in cohorts so we can keep improving the participant experience, and every project is open source. Everything happens in the open on Discord and GitHub.
Cohort 8
LeetCode StudyPrepare for coding interviews by solving the Blind 75 together over 15 weeks. Submit solutions as GitHub PRs, review each other, and stay motivated with the leaderboard, earning a certificate on completion.Learn more →

Dale UI Design SystemAn open-source React design system specialized for the Korean user experience. Designers and developers experience a real-world collaboration process, from issue triage to releases.Learn more →
Cohort 4
AI StudyA practical AI study open to any developer, not just AI engineers. Experiment with LLMs and modern tools together, and apply what you learn to everyday development work.Learn more →
Cohort 1
Blog StudyPublish one post a week on your own blog for ten weeks. Writing alongside peers builds the consistency that is hard to sustain alone.Learn more →Programs that mature with every cohort
Retrospectives and feedback carry into the next cohort: a virtuous cycle at the heart of how DaleStudy runs its programs.

2Collaborate on GitHubPRs, code reviews, and issues: the same open process as real-world work.
3Share the resultsSolutions, posts, and releases accumulate and become stepping stones for the next cohort.
4Retrospect & improveEach cohort ends with a retrospective that improves the next, and graduates return as coaches.
Reviews
Stories written by the participants themselves: the voices that show best what DaleStudy is like.
LeetCode Study
“The study lays out a 15-week problem roadmap and makes you review each other's code. That simple system is a remarkably powerful support.”
Ju HwijungLeetCode Study
“Studying unfamiliar data structures and getting code reviews from senior developers: valuable experiences that are hard to come by as a junior.”
Sam LeeLeetCode Study
“I got high-quality reviewer feedback outside my company. Beyond solving problems, I learned how to write better code.”
ReeseLeetCode Study
“Because we were working toward the same goal together, I kept solving problems consistently. Writing solutions hoping to help others even a little made me write more careful code, too.”
Dongyeong ChonLeetCode Study
“The biggest change was how I approach a problem. I used to just start coding; now I weigh time and space complexity first and think about which data structure and algorithm fit before touching the keyboard.”
E.M. LeeLeetCode Study
“Thanks to DaleStudy's system for reviewing code across languages, I finished the cohort while picking up five new languages. You just solve and post reviews, and before long you are a contributor across every directory on the leaderboard.”
yhkee0404Dale UI
“From issue triage to release, I experienced a design-system release process that is hard to get even at work. Now my portfolio includes a package people actually use.”
AI Study
“Presenting felt intimidating, but sharing in rotation every week turned me into the person who tries AI tools first at work.”
Blog Study
“Alone I never made it past three posts; writing together, finishing feels within reach. Peer reactions and feedback motivate more than any deadline.”
