Ssokdak-Ssokdak
A digital therapeutic that treats early-stage depression through emotion journaling
Context
I led a five-person product engineering team at an early-stage startup aimed at treating depression early.
Problem
Depression responds to early intervention, but nothing connected a person’s day-to-day emotional record to actual treatment.
How I solved it
- Led a five-person product engineering team and ran project management
- Designed the service architecture and built out the infrastructure
- Built server features: journal entry and retrieval, onboarding and auth, reminder notifications
- Extracted emotional factors with LLM and recommender models, then matched users to conversation partners on that basis
Result
- Launched Ssokdak-Ssokdak v1.0
- Selected for TIPS, securing ₩500M in funding, and drew up the R&D programme plan
Impact
Shipping the product and landing government R&D funding together gave the team runway for its next stage.
