Welcome to Code & Candlesticks

I'm Luis — a senior technical product manager at Square, where I build high-integrity fintech systems with precision, purpose, and a hacker’s mindset. I thrive at the intersection of compliance, data, and engineering — leading cross-functional teams to deliver systems that scale securely and efficiently.

Outside of work, I’m a code-crunching, chart-watching, coffee-fueled force of curiosity. I spend my late nights / early mornings and weekends building Python trading bots, integrating APIs, automating daily routines, and pushing the limits of what scripting and machine learning can do in real markets.

I’m also a Montessori dad, a CrossFit comeback kid, and a fierce advocate for my family’s well-being — from decoding school applications to hauling mini Goldendoodles across the country, all while planning weekend soup recipes and debugging batch files.

This blog is where I share my tools, experiments, experiences, and thoughts — from backtesting engines and market sentiment checkers to product development best practices and workflow automation hacks. You can also check out my full CV here.
