Founder-CTO & AI Product Engineer

Seoul, South Korea

Welcome

I’m a technical founder, CTO, and AI/full-stack engineer based in Seoul. My work sits at the intersection of product judgment and deep engineering execution: turning messy real-world workflows into software people can trust, use, and pay for.

Right now I spend most of my time on two products:

  • HoverNotes, a privacy-first AI video note-taking product that turns online lectures, tutorials, and course videos into structured notes users can keep in their own Obsidian/Markdown workflows. I founded and built the product across Chrome/Edge extension workflows, a Next.js web app, realtime video-in notes-out AI workflows, payments, analytics, localization, SEO, and production operations. As of June 2026, HoverNotes is doing over $10K/month in revenue with around 20K installs across Chrome and Edge.
  • Quest, a safari quotation platform for tour operators. I co-founded Quest as CTO and lead a 3-person engineering/product team building operator dashboards, admin tools, travel requests, itinerary planning, pricing, branded PDF generation, quote email delivery, content libraries, billing, and release workflows.

I also contract with xAI Human Data on software-engineering model evaluation, reviewing AI-generated code across languages and domains to help improve coding-model quality.

Before this, I was a Lead AI Engineer at Bebridge/Slid, a 50K+ MAU EdTech platform, where I took on principal-level AI engineering work: setting technical direction, solving hard AI/product problems, and shipping LLM-powered auto-notes, AI chat, semantic search, transcript correction, mobile AI workflows, real-time transcription, cross-platform auth/payments, and multi-format exports.

Engineering Focus

  • AI product systems: LLM workflows, multimodal AI, RAG, coding-model evaluation, AI note generation, transcript correction, and learning tools.
  • Full-stack platforms: TypeScript, React, Next.js, Python/FastAPI, Node.js/Express, PostgreSQL, Supabase, Drizzle ORM, MongoDB, and Redis.
  • Workflow infrastructure: browser extensions, local-first Obsidian workflows, rich editors, PDF/document generation, email delivery, Cloudflare R2, Stripe, Razorpay, Vercel, AWS, Docker, PostHog, and Sentry.

My engineering philosophy is simple: put users at the center, move fast but measure real behavior, build the whole loop from product to reliability, and stay calm under ambiguity.

Background

I graduated Magna Cum Laude from Korea University with a B.S. in Electrical and Electronics Engineering and a 4.02/4.5 GPA. I received both the Ugandan Government Scholarship and the Global Korea Scholarship.

I co-authored a Springer Nature Computer Science paper on responsible AI and interpretable machine learning, and I have contributed to developer tools and AI/open-source ecosystems including LangChain, Vercel AI SDK, Editor.js, Redux Toolkit, MemGPT, Pytube, FastAPI, and related projects.

I also serve as Vice President of the Ugandan Community in South Korea, supporting governance, embassy-facing communication, partnership strategy, and community engagement.

Connect

I’m open to senior/principal engineering conversations, technical advisory, AI product collaborations, privacy-first AI, coding agents/model evaluation, and workflow automation.
