I'm Dan Lozada. I live in Boston, where I'm building Klaviyo

I’m a software engineer and entrepreneur. I’m currently working on Klaviyo — an omni-channel marketing platform used by millions of businesses.

I studied applied economics at Case Western Reserve University. My educational background is in quantitative economics, statistics, and data science. I have a passion for building products that solve real problems.

I’m a self-taught software engineer. I’ve been building websites, APIs, mobile apps, CLI tools and more for a number of years. I'm largely language agnostic and I'm always looking to learn new things, but I've been working with JavaScript, TypeScript, and Python a lot recently.

As the founder of SupplyNow, I worked on building multi-tenant marketplace applications. My work spanned the entire stack, from the database to the frontend (and the infra that makes it all possible). Aside from building product, I was also responsible for planning, implementing, and distributing analytics through data pipelines and dashboards for a variety of stakeholders.

As an engineer on the Onsite Team @ Klaviyo, I work on developing software that runs on hundreds of thousands of website and used by Billions of people every month: klaviyo.js
