Robert User

I am a senior full-stack software engineer with 10 years of experience building scalable web applications across startups and high-growth tech companies. I specialize in modern JavaScript frameworks and backend technologies, designing APIs, leading product features end-to-end, and optimizing performance in complex systems.

At Oscar Health I helped build scalable healthcare platforms, improving frontend load times by 35% and backend performance by 30% while ensuring HIPAA compliance and implementing real-time, event-driven architectures. I also contributed to DevOps and infrastructure automation with Terraform, Kubernetes (AWS EKS), Docker, and CI/CD pipelines.

Previously at Robinhood I engineered high-impact systems including a viral pre-launch referral waitlist and scalable microservices for account management and trading features, processing millions of daily transactions with high reliability. I focus on developer experience, clean architecture, cross-functional collaboration, and mentoring engineers to deliver reliable, user-centered products.
