Full-Stack Engineer | Web Apps, APIs & AI Integrations

I help founders and product teams build and improve web applications without having to coordinate separate frontend and backend developers. Within an agreed scope, I can own the flow from the user interface and APIs to databases, integrations and deployment.

I can help you launch an MVP, finish an existing product, connect AI capabilities to real workflows, or improve backend reliability. My experience includes a multilingual consumer astrology and AI web service, fintech and Web3 backends.

My stack includes TypeScript, React, Next.js, Rust, Python, Go, PostgreSQL, Docker and cloud services. I use AI-assisted development with independent review and testing gates, not unchecked generated code.

Before starting, we agree on deliverables, milestones, testing and handover. Based in Seoul, South Korea; available remotely for up to 40 hours per week at USD 75/hour.
