I build secure, scalable full-stack systems with Java, React, and AWS.
United StatesWhat I'm looking for
I’m an experienced Full Stack Developer with 13 years in software engineering, specializing in backend and frontend development using Java, JavaScript, React, and Spring Boot. I focus on building high-quality, secure, and scalable applications, with a strong track record in RESTful API design, asynchronous processing, and performance optimization.
At Meta, I architected distributed backend services on Java, Spring Boot, and AWS to improve scalability and security while strengthening cross-team collaboration. I engineered secure authentication and authorization workflows using OAuth 2.0, JWT, and OpenID Connect (OIDC), designed scalable RESTful APIs, and led asynchronous message processing with AWS Lambda—along with monitoring dashboards using AWS CloudWatch to improve operational visibility. I also automated deployments through CI/CD pipelines and improved frontend responsiveness and accessibility with React, HTML5, CSS3, and Sass, raising testing coverage to 85%.
Previously at Microsoft and Cognizant, I developed and modernized enterprise cloud applications—improving API performance, observability, and reliability while supporting production and architecture reviews. I’ve also consistently partnered with product and engineering teams in Agile Scrum environments, and I mentor others to raise engineering quality through shared best practices in React, JavaScript, and backend development.
