Full-stack Engineer @ Soundmind · Founding Member @ WIGTN Crew
Building harnesses for AI workflows · Designing systems that run without humans in the loop

Portfolio · WIGTN · WIGTN-Coding Plugin

I work at the intersection of B2B operational systems and AI-native engineering.

• Designed a multi-tenant auth & permission platform from scratch, serving multiple B2B partners on a single infrastructure
• Solved high-throughput operational issues — reduced DB write load by 95% under 3,000~5,000 events/min
• Building open-source harnesses that let AI agents produce consistent, verifiable output without human intervention
• Won ByteDance Build with TRAE Hackathon (Grand Prize) and Snowflake AI & Data Hackathon Korea (Runner-up) with multi-agent verification workflows

"Systems run reliably not because someone patches them every time, but because they're built to not break without a human in the loop."

Founding member of WIGTN, a 5-person AI engineering crew building harnesses and tools for AI-native development.

A plugin that lets multiple AI agents collaborate on real codebases without losing context or quality.

• Role-based SKILL.md definitions for PRD writing, architecture design, parallel development, and code review
• Validation gates between stages — only output that passes quality checks advances
• Designed for teams: the same workflow that works for one developer scales to many
