Technical leadership at the intersection of
systems, health-tech, and AI.

I'm a Principal Software Engineer who owns technical architecture end-to-end — from system design through production deployment. My work focuses on building the backend infrastructure and real-time data pipelines that power regulated, high-stakes platforms.

Currently at Smart Tubing in Palo Alto, I lead the engineering team building a medical IoT platform that manages over a million connected devices. I designed the event-driven architecture (MQTT, message queues), built the high-throughput APIs, and established the CI/CD pipelines that meet medical-grade reliability requirements.

Before that, I led squads of 10+ engineers at a European consultancy serving Credit Agricole, and built banking platforms for BTG Pactual and Banco ABC. I bring deep experience in regulated environments where reliability, auditability, and security are non-negotiable.

Distributed Systems & Cloud Architecture

Event-driven pipelines, microservices, high-throughput APIs, message queues (Kafka, RabbitMQ, MQTT). AWS, Docker, Kubernetes, Terraform.

AI & Data Integration

Predictive caching algorithms, ML-ready data pipelines, LLM API integration, vector databases (RAG), MLOps platforms.

Regulated Environments

Medical device platforms (FDA-adjacent), banking systems (Credit Agricole, BTG Pactual). Emphasis on reliability, auditability, and compliance.

Engineering Leadership

Mentoring senior engineers, owning roadmaps, architectural reviews, cross-team collaboration with Product and Program Management.
