What I'm looking for
I am a Senior Software Engineer with over 10 years of experience in designing and developing enterprise-grade software across various domains, including healthcare, e-commerce, and logistics. My expertise lies in Java and Spring Boot, complemented by full-stack capabilities using modern JavaScript frameworks. I have a proven track record of building scalable microservices and cloud-native applications, ensuring high performance and maintainability.
At Taivara, I developed multiple SaaS platforms, engineered microservices using Spring Boot and Kafka, and deployed them into AWS EKS clusters. My role involved integrating with third-party APIs and designing secure RESTful APIs, while also maintaining a focus on performance tuning and database optimization. I enjoy collaborating with cross-functional teams and mentoring junior developers, sharing my knowledge of clean architecture and effective API management.
Previously, I worked at Ingenious Results and Sentara Healthcare, where I developed custom logistics applications and core clinical systems. My experience includes migrating monolithic applications to microservices, implementing OAuth2-based authentication, and creating complex reporting dashboards. I am passionate about leveraging technology to solve real-world problems and continuously seek opportunities for growth and learning in my field.
