United StatesWhat I'm looking for
I am a Staff Software Engineer with deep experience building full‑stack, cloud‑native systems that power real‑time communication and healthcare platforms. I've led architecture and implementation of high‑performance microservices, event‑driven pipelines, and interactive frontends using Java, Go, Python, React, and Kubernetes.
At Salesforce I architected core Health Cloud platform features, HL7/FHIR integration engines, and AI/ML‑enhanced clinical tooling that improved clinician workflows and ensured HIPAA compliance; at Twilio I led real‑time media and SFU infrastructure, adaptive bitrate streaming, and scalable orchestration systems for millions of users.
I focus on observability, secure multi‑tenant architectures, and automated CI/CD to deliver resilient, low‑latency services. I mentor engineers, drive technical reviews, and align engineering efforts with product and operational goals to ship reliable, impactful solutions.
