FAQ
How do you collaborate with teams in Seoul?
I support meetings and real-time collaboration in the KST timezone. I also use async communication (Slack/Linear) for maximum flexibility.
Do you serve nearby cities like Incheon, Suwon?
Yes. I cover Seoul and surrounding areas within the same timezone. Working remote-native means physical distance is never a barrier.
What engagement models are available in Seoul?
You can choose fractional (2-3 days/week), project-based sprints (4-8 weeks), or a monthly advisory retainer. All engagements start with a one-week paid trial.
Do you have experience with Seoul startups?
Yes. I have delivered mobile apps, web platforms, and architecture audits for startups and enterprises in Seoul and across APAC.
What timezone overlap do you offer for KST teams?
Typical overlap is adjustable within KST business hours (roughly 9 AM – 3 PM KST). Weekly check-ins and urgent reviews are scheduled in this window.
