Engineering with a researcher’s curiosity.
I am a software engineer with 4+ years of startup experience building production mobile and backend systems. I started in Flutter, moved into Java and Spring Boot, and learned to care about the operational details that make software dependable.
Alongside engineering, I research secure federated learning for health IoT. My work focuses on moving expensive privacy operations toward edge infrastructure so wearable devices can stay lightweight.

Jul 2025 – Dec 2025
Research Assistant @ CSU Dominguez Hills
- Built federated learning pipelines in TensorFlow with CKKS homomorphic encryption for health IoT data.
- Implemented secure aggregation with in-network computing, moving encryption overhead from wearables to edge nodes.
- Reached F1 > 0.93 and packet delivery ratio > 0.94 on synthetic healthcare datasets.

Full Stack Engineer @ Floryn Health
- Joined as a Flutter developer, moved into backend: REST APIs and services in Spring Boot with PostgreSQL for healthcare workflows.
- Implemented auth with Spring Security and JWT on the then-new Spring Boot 3, using sparse docs and community resources after the effort had stalled for about three weeks.
- Built Jenkins CI/CD pipelines on GCP and containerized backend services with Docker.
- Improved deployment frequency by ~3× over manual releases.
