Individuals in their 50s with career experience typically hold 3-5 certifications (Professional Engineer, Industrial Engineer, Safety Manager, Insurance Planner, etc.), each with different renewal cycles (1-5 years), continuing education requirements, and renewal application agencies. They must check each agency's website separately—such as the Human Resources Development Service of Korea, the Financial Supervisory Service, and the Korea Occupational Safety and Health Agency—and missing a renewal deadline invalidates the certification, requiring months and KRW 1,000,000-3,000,000 (approx. $750-$2,250) to reacquire. Especially when transitioning to freelance work after retirement, certification validity is often a prerequisite for contracts, so invalidation leads directly to income loss.
When users register their certifications on the web (certification name + acquisition date + issuing agency), the service (1) automatically maps each certification's renewal cycle and continuing education requirements, (2) sends email and KakaoTalk reminders at D-90, D-30, and D-7 before the renewal deadline, and (3) provides a single screen comparing available continuing education institutions, schedules, and costs. Uploading a photo of the certification automatically inputs basic information via OCR.
