About
Engineered to ship.
I'm Emanuel Hernandez, a software engineer based in Berkeley, CA, with a B.S. in Computer Science from University of California, Davis. I work across the stack — React and React Native on the frontend, Go and Node.js on the backend, PostgreSQL and Docker in production.
At AggieWorks I built features for Moober, a campus rideshare app with 2,000+ active users. At MESA I maintained coding environments for 4,000+ students and architected an alumni database serving 2,000+ graduates across Sacramento-area school districts.
Experience
Where I've built.
- Facilitated technical workflows for 20+ weekly engineering workshops, maintaining 99.9% uptime for coding environments used by students across the greater Sacramento Area.
- Architected a centralized Alumni Database for 2,000+ graduates, automating data entry processes and reducing administrative overhead by approximately 15 hours per week.
- Streamlined the deployment pipeline for student-facing web applications, mitigating production bug reports by 25% and ensuring consistent software delivery for 4,000+ users across multiple school districts.
- Engineered 15 high-impact features for Moober, a rideshare app tailored for UC Davis students, significantly enhancing the app's functionality leading to 75% ride conversion rate.
- Containerized the backend and database for 2,000+ active users with Docker Compose and an entry point that runs Drizzle migrations and seeds automatically on container startup, saving the organization over $800 yearly.
- Executed a PL/pgSQL archiving system that reclaimed primary database storage requirements by 40% by offloading expired conversation data via scheduled Cron jobs.
- Optimized ride management APIs with Drizzle transactions, reducing database lock contention by 30% during peak ride request windows.
Projects
