Hi, I'm Kibaek

AI & Full-Stack Engineering Leader · Founder · 15+ years shipping production systems

I design and ship AI systems that hold up in production: LLM agents, retrieval pipelines, evaluation frameworks, and the data platforms underneath them. I have taken AI products from a blank repo to live customers as a founder, led engineering teams in enterprise settings, and defined the AI standards that other engineers build on.


What I Do

  • Lead AI initiatives from 0 → 1. I identify where AI solves a real customer or operational problem, align stakeholders across departments, and own delivery end to end: architecture, model serving, evaluation, and production support.
  • Build agentic and retrieval systems over real enterprise data. Multi-agent workflows, hybrid retrieval with reranking, citation-grounded generation, and streaming LLM orchestration across OpenAI, Anthropic, and open-source models.
  • Make AI measurable. I establish evaluation practice on Braintrust: regression datasets, scoring rubrics, prompt and retrieval A/B tests, and model comparisons that gate every change before it reaches users.
  • Engineer for cost and latency. Edge-optimized open-source model stacks, Redis-backed caching, model-aware routing, and on-device inference. One deployment cut AI operating costs by 40% with no loss in response quality.
  • Grow engineers. I have managed a team of four, mentored 8+ engineers, and set the prompting, review, and integration standards that raised team throughput and shortened PR cycle time.

Currently

  • Founder & Principal Engineer, Dotori.ai — Built CosReg, a live multi-agent compliance analyst that screens cosmetic formulas against 86,000+ ingredients across US, EU, and global regulations, and Signal, an ML price-prediction platform delivered through web and API.
  • AI / Senior Full-Stack Engineer at a national membership organization serving 3M+ members — Drive the organization's AI program: a production RAG platform over 10+ years of institutional data, a voice-enabled AI advisor agent, agentic workflows over a 6.9M-contact CRM, and the enterprise BI platform they reason over.
  • Graduate Researcher, Columbia University — Open-source AI ecosystems and enterprise adoption: data sovereignty, model licensing, and open-vs-proprietary tradeoffs.

Featured Work

LLM Infrastructure & Agents

  • ollama_exo_proxy_server — Secure, high-performance LLM inference gateway for distributed Exo and Ollama clusters. Model-aware routing and load balancing, API-key security, rate limiting, built-in RAG and vector search, Redis-backed KV caching, and application-level cluster management without Kubernetes. FastAPI · Gunicorn · Redis · MongoDB · ChromaDB · Nginx · Docker

How I Work

  • Ship, measure, iterate. Fast to a working system, rigorous about measuring it, disciplined about what changes next.
  • Build vs. buy on evidence. Hosted APIs where they win, open-source models where they win, and the numbers to show which is which.
  • Standards over heroics. Reusable patterns, review discipline, and documentation so the team moves faster than any one person.
  • AI-first delivery. I use Claude, Cursor, and similar tools daily across design, scaffolding, refactoring, and testing, and I teach teams to do the same well.

Education

  • M.S., Applied Analytics — Columbia University
  • B.E. — The City College of New York

Let's Connect

I am always open to conversations about LLM infrastructure, agentic systems, evaluation, and building AI teams. Ask me about Python, LLM system design, retrieval, and taking AI products from concept to production.
