Engineering Resilience & Intelligent Systems

I turn messy text into navigable knowledge.

I build robust, scalable solutions that bridge the gap between complex data and accessible user experiences. Specializing in automation, AI integration, and system architecture.

Breaking the Science Lock

For 25 years, ranked-by-popularity search has quietly decided which science you are allowed to find. The rest is still in the literature — unindexed, unreachable. This is the R&D on getting it back.

  • Experimental interface patterns
  • Focus on cognitive-load reduction
  • Research-driven methodology

Proof of Work

I don't just write code; I engineer systems. My work focuses on creating tools that empower users to handle complex data with ease. From automating mundane administrative tasks to leveraging Large Language Models for semantic understanding, I build software that works.

Backend

Python, FastAPI, Node.js, PostgreSQL

Frontend

React, TypeScript, Tailwind, Office.js
