Designed, implemented, and maintained the backend systems for the Keeper password manager and data vault .This involved architecting solutions with AWS and Terraform, writing Java code for REST APIs and batch jobs, Linux system administration, and administering the MySQL database. Also I managed system access, setup Jenkins jobs, configured NGINX, and created services using Docker.Also, I designed Keeper’s authentication system and I designed the cryptographic protocols used to store and transmit password data and files. I analyzed of our software and infrastructure for security vulnerabilities.

Primary work involved writing Java code and the JSP, JS, HTML, and CSS to support the web application.I had a special focus on security. I implemented fixes for problems found in the Ernst and Young security audits, I designed and implemented encryption key management system for PCI compliance, and I was the primary development contact for security-related issues.

Developed, optimized, and tested J2EE web applications using JSP, Apache Struts, and Hibernate frameworks. The applications used the Apache Tomcat servlet container and a MySQL database.
