A sign of powerful software is when you can replace multiple languages, frameworks, and repositories with one tool applying a clever abstraction, and doing so makes things simple, cheaper, and faster. I can only think of one or two examples. Right now, I'm seeing this with Chalk as it replaces big parts of a pretty serious enterprise ETL pipeline. (And no, I'm not affiliated with Chalk. Their software is just legitimately impressive.)

Q: What's something people are always surprised to learn about you? I have moved 45+ times and lived in 4 countries. 🇺🇸 🇪🇸 🇩🇪 🇨🇷

Q: What made you say yes to Chalk? The product has unlimited potential, and I’m excited to be back in an early-stage environment where I can help build — not just operate.

Q: What's the last great book you've read? I just finished Homage to Catalonia by George Orwell. It does a great job of stripping away the mythology of war to give readers an unsentimental view of what it was like to serve on front-lines in a time of incredible social upheaval and consequence

Q: What drew you to Chalk? First, the technology. I think Chalk has a category-defining opportunity ahead of it, and that’s an opportunity I relish. Second, the stage. I’m a builder at heart. Helping define how to deliver value at scale to Chalk customers and, in turn, enable them to deliver unprecedented value to their own customers, is exciting. Third, the people. I do my best work when I’m surrounded by kind, driven people who are smarter than me.

Most ML teams write the same code twice 🐫 Data scientists prototype in Python. Engineers rewrite for production. By the time it ships: multiple rewrites, multiple systems, nobody has the full picture. This is what MLOps was created to solve. We broke down the challenges + how teams are eliminating rewrites entirely: chalk.ai/for/mlops
