Senior Full Stack Engineer specializing in cloud-native systems and AI-driven product platforms.
United StatesWhat I'm looking for
I am a Senior Full Stack Engineer with 7+ years building cloud-native, microservice-based platforms and end-to-end web applications. I focus on scalable backend systems (Java, Spring Boot) and modern frontends (React, Next.js) integrated with AI capabilities.
At Datadog I led full stack modules for an AI Insights platform processing billions of telemetry events daily, implemented AI-driven anomaly detection with OpenAI and TensorFlow Serving, and integrated LangChain to automate root-cause summaries, reducing debugging time by 45%.
Previously at Netflix and Asana I designed personalization and productivity systems, built recommendation and realtime analytics pipelines (Kafka, Elasticsearch), and improved frontend performance with SSR and component-driven architectures. I have hands-on experience with CI/CD, containerization, and secure multi-tenant architectures.
I bring a pragmatic, data-driven approach to engineering, prioritizing observability, reliability, and secure design while collaborating closely with ML and DevOps teams to deliver production-ready AI features and high-performance user experiences.
