O mnie
Backend developer with 12+ years of experience. I build web scrapers, API integrations and automation that keeps running: pagination, rate limits, retries and logging included.
Stack: Python, Node.js, TypeScript, Java and Spring Boot, PostgreSQL, MySQL, MongoDB, AWS, Cloudflare Workers.
Recent work: a Google Search Console MCP server, marketplace data pipelines, payment and kiosk software with PG integrations, Excel and Google Sheets automation.
How I work: everything in writing and asynchronous. I send a short written scope and milestone plan before starting, show a working screen early so you can correct the direction, and reply within 24 hours (Korea time, GMT+9). I do not take calls or video meetings. Based in Seoul.
