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:
- SearchLink, a live SaaS I built and run alone (Cloudflare Workers + D1, OAuth, billing, MCP server): https://searchlink.namubase.com
- Marketplace extensions that passed store review: VS Code https://marketplace.visualstudio.com/items?itemName=sellerkit.httprunner, JetBrains https://plugins.jetbrains.com/plugin/34045, WordPress.org https://wordpress.org/plugins/podsync-for-woocommerce/, Apify https://apify.com/sellerkit/google-trends-scraper. Also an Atlassian Marketplace Jira app (vendor: Global Match Hub).
- Longer write-up of past paid work (kids news app on Flutter + Spring Boot WebFlux, unmanned study cafe system with payments and door control, healthcare platform on Laravel + React): https://dev.to/globalmatchhub_b7ad9cba/i-ship-backends-alone-in-writing-12-years-6-products-live-right-now-92p
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.
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. I am happy to do a small paid first task so you can judge the quality before committing to a month or a year.
