About me.

Daniel Miranda

I'm a full-stack engineer based in the SF Bay Area.

Currently working at Mozilla Foundation, where I help build and maintain the platforms that support our mission for a safer internet.

Outside of work, I enjoy working on cars 🚗, cycling 🚴‍♂️, and spending time with my younger brother 👦🏻.

Where I've worked.

2021 — Present

Full-Stack Engineer

Mozilla Foundation · Web Platforms Team

Build and scale the multilingual, open-source platform powering mozillafoundation.org and mozillafestival.org using Django, Wagtail, and modern frontend tooling.

Lead end-to-end delivery of revenue-critical donation features and consent-aware A/B testing functionality. Re-architect sitewide systems to support safe experimentation, complex content migrations, and high-impact feature rollouts without disrupting production. Provide architectural guidance and PR reviews across the stack.

Full-Stack Developer

Kaiser Permanente · Automation Team

Built and modernized internal web applications used by operations and engineering teams. I worked across the stack — React frontends, Django/REST APIs, and supporting infrastructure workflows — partnering with stakeholders to ship tools that improved visibility and reduced manual work.

Highlights included consolidating system and data center information into dashboards, creating workflow tooling that reduced friction during technical incidents, and migrating legacy apps onto the team's supported stack.
