What I'm looking for

I am seeking a senior engineering role where I can build scalable, cloud-native systems, improve reliability, and collaborate with product and design teams to deliver impactful user-centered solutions.

I am a full stack developer with over 10 years of experience building scalable web applications using Java, Spring Boot, Node.js, React, Angular, and Vue.

I specialize in microservices, Kafka, Kubernetes, and cloud deployments, and have modernized legacy healthcare systems to improve reliability by ~40% and reduced API latency by 50%.

I have designed CI/CD pipelines (Jenkins, GitHub Actions), managed Docker and Kubernetes deployments on AWS, and implemented real-time IoT and predictive maintenance solutions processing ~100M records in 2 hours.

I collaborate closely with product managers and designers to deliver user-centered features, optimize performance, and ensure reliable operations in production environments.
