OPEN SOURCE CONTRIBUTOR DevSum

Hey, I'm Erik, a software engineer who ships real products. React Native marketplaces, Chrome extensions, AI pipelines, and client websites built for performance. I care about clean architecture, real user problems, and code that doesn't embarrass future me.

I specialize in TypeScript across the full stack, from Expo mobile apps and Astro sites to Node APIs and Supabase backends. If it ships to real users, I want to build it right.

Currently open to full-stack or mobile SWE roles in San Diego or remote.

40-page site for a Jewish and Israeli mental health 501(c)(3). Stripe Payment Links shop, Givebutter donations, and volunteer/contact forms. Sanity CMS with a publish webhook that rebuilds the site in under a minute; a failed fetch during a build degrades a section instead of failing the deploy.

PORTSMITH

Chrome extension for migrating AI assistant configs between ChatGPT, Claude, and Gemini. Mapped each platform's internal web API from network traffic, translates through one interchange schema, and checkpoints writes so an interrupted migration resumes without duplicates. No PortSmith servers, no analytics. Live on the Chrome Web Store.
