What I'm looking for

I’m looking for remote, Agile teams where I can build scalable cloud-native products—own event-driven microservices and serverless systems, strengthen CI/CD and reliability, and keep improving performance with minimal guidance.

I’m a Senior Full Stack Software Engineer with 7+ years of experience building scalable, cloud-native applications. I design and deliver event-driven architectures, microservices, and high-frequency data processing systems using AWS Lambda, DynamoDB, S3, SNS/SQS, and CloudWatch—helping teams build reliable products at scale.

At HeartFlow, I built AWS serverless applications supporting 10M+ monthly users and improved performance and maintainability with React.js, TypeScript, and Node.js. I’ve also led CI/CD and automated testing to reduce deployment risk, and I streamed real-time data with Kafka to lower processing latency while collaborating across teams to improve uptime and reduce MTTR.
