Sangyoon Lee, full-stack developer, 13 years (small teams, one person from spec to production to the pager). Everything below is public, so you can check it instead of taking my word:
Passing a marketplace review means finding the bugs before submission, so QA and verification are how I work: I find what breaks before your users do. In 13 years I have never missed a KPI I was given. Whatever number you measure me on, I will hit it, and I will report progress against it in writing every week.
Open to: a monthly salary-style retainer (part-time or full-time), a 12-month contract, or fixed-price projects (web/API development, QA and test automation, Ansible/DevOps, integrations). Also happy to be the quiet backend partner behind a small team. Available now.
How I keep it low-risk for you: I work fully in writing (email/Slack/Notion, async), no calls, and everything is documented. Your code lives in a repo you own from the first commit, with handover notes. Instead of an interview, the first small task is free. We agree on the scope in writing first (up to about 10 hours of work), and I deliver within a week with a short written update every day. If you like the result, we continue on a paid basis. If not, you've lost nothing. One free task per company.
