These days I spend most of my time thinking about the intersection of business strategy, product thinking, and AI systems. I'm particularly interested in how organizations can adopt AI tools practically — not just as demos, but as production systems that solve real problems.

I learn by building. My current focus is on understanding agentic AI systems — what they can actually do, where they break down, and how to evaluate the trade-offs between complexity and value. I write about what I learn so that others navigating the same questions can benefit from the experiments I've already run. I hope to write for people who want to understand AI through the lens of building and decision-making, not just theory.

  • What "Agent" Actually Means: Lessons from Building My Morning News Digest
    February 2026 · 10 min read · Part 1 of 2
    I built the same thing three times — each with a different level of "agency." Here's what I learned about what that word actually means, why automatic doesn't equal autonomous, and how to think about the spectrum of agency in AI systems.

  • Inside Out: ML & Lexical Rule-Based Emotion Classifier for Text
    January 2020 · Capstone Project
    A Flask web application that analyses textual input to classify emotions at the sentence level, combining a Logistic Regression model (trained on ~500k tagged observations) with VADER valence scoring and TextBlob phrase extraction. Deployed on Heroku.
