Resume

I built an agentic AI question editor with tool-calling and streaming edits. It generates and revises exam questions from text and images.

I designed a multi-provider AI audit pipeline with automated fallbacks and quality gates for AI-generated content.

I built similar-question generation and a remedial flow that creates practice from student mistakes.

I created interactive math and economics visualizers for probability, integration, vectors, and supply-demand.

I led the move of legacy AI features into a new monorepo. The work covered a shared cipher package and large data migrations.

I built a role-based production platform on Supabase for quoting, planning, live collaboration, and staged payouts.

I designed RLS-first PostgreSQL schemas with multi-step approvals, audit logs, and role-scoped access.

I added secure file uploads through Supabase Edge Functions to Wasabi with signed URL caching.

I worked on frontend and Web3 flows for a multi-chain dApp on Ethereum and BSC, including NFT minting, token sales, and vesting.

I added wallet connections with Wagmi, Viem, and Reown AppKit. I kept on-chain, backend, and UI state in sync in a React and Vite codebase.

I designed and deployed secure APIs with NestJS, PostgreSQL, and Drizzle ORM for counseling and scheduling.

I built real-time chat with presence, file sharing, search, and unread tracking using Ably. Delivery latency was under 200ms.

I automated Zoom sessions and notifications with Bull and Redis.

I containerized the app and deployed it on GCP Cloud Run.

I added retry logic to scheduled jobs. The failure rate dropped by 40%.

I added optimistic updates, request polling, and queueing to improve app response.

I optimized SEO and performance. Lighthouse scores moved into the 90s.

User engagement rose by 25% after faster loads and interactive UI.

I kept the app stable across devices and browsers with unit tests and regression checks.

I shipped features on time with designers and backend teams.

I shipped more than seven production apps for healthcare, POS, and CMS for Korean clients.

I built apps with React, Next.js, and React Native.

I built a CMS with Next.js and Firebase with real-time updates and thermal printer support.

Order delays dropped by 60% after printer support for receipts.

I chose stacks and libraries that kept the code easy to maintain.

I studied programming, databases, and information systems

I built a base in software engineering

I completed an intensive full-stack web program

I practiced modern software engineering
