Profile: https://flows.cv/johnk

I'm a Senior Software Engineer at Formation Bio, where I build AI-driven applications that accelerate drug development and clinical trials. My work spans everything from multi-agent systems capable of complex decision-making and human-level output, extracting high-value data from challenging biomedical sources using computer vision, to agentic web crawlers for retrieving and cleaning data to drive decisions. I've delivered on many large projects zero to one, and enjoy working across the tech stack.

I want to work on solving meaningful, complex problems that improve people's lives. Please do not contact me about roles in finance, advertising, gambling, surveillance, military/defense, or platforms that exploit labor.

## Work Experience
### Senior Software Engineer @ Formation Bio
Jan 2023 – Present | New York, New York, United States
Over the past two years, I’ve focused on applying LLMs and related technologies to build complex multi-agent systems that support research and patient recruitment. I lead architecture and implementation of the backend for Muse, a clinical trial recruitment tool developed in partnership with Sanofi and OpenAI.

Beyond general web application development in Python and TypeScript (React, NestJS), I’ve worked across the AI/ML stack: from computer vision for state-of-the-art data extraction in scientific literature, to multi-agent systems for complex decision-making and agentic web scraping.
