- Leadership & Mentorship: Led and technically mentored three development teams, fostering a collaborative and innovative environment.
- Architectural Design: Applied Domain Driven Design principles to architect and develop a CQRS-based, scalable, and highly available multi-tenant access management system, Security360. Implemented fine-grained access control (Role & Attribute Based Access Control) to secure web applications and services.
- Product Development: Designed and developed multiple web services, cron jobs, and event/stream processing applications integral to Security360.
- Performance Optimization: Converted the authorization service to a native application using GraalVM, reducing startup time from 8 seconds to under 500 milliseconds, significantly enhancing scalability and memory efficiency.
- Auditing & Reporting: Implemented comprehensive auditing and reporting capabilities for Security360 using Hibernate Envers.
- Library Development: Developed Spring Boot auto-configuration and Quarkus extension libraries to streamline the integration of Security360 with web applications and services.
J.B. Hunt Transport Inc – Senior Software Engineer – Lowell, AR, USA – 06/2019 – 01/2021
- Leadership & Mentorship: Assisted and mentored the team, enhancing their skills and productivity.
- Security Expertise: Acted as the go-to person for application security issues across the company, providing solutions and troubleshooting.
- IAM Analysis & Implementation: Reviewed and analyzed access requirements with IAM providers like Okta, Azure AD, and Keycloak. Selected and implemented the commercial version of Keycloak (RedHat SSO) with paid support from Red Hat.
