Backend Developer (Java, Spring Boot) for Rapid7's Application Security (AppSec) platform, delivering scalable RESTful services and micro-services to support critical workflows.
Designed and implemented a service that leveraged Kubernetes Java client to automate critical tasks. The REST API was used to create a specific job that when enabled or scheduled (cron jobs) would perform a task. Adapted by the team, significantly reducing time on manual tasks. Example of jobs I created using this service:
Job 1: Detected and shut down long running stuck EC2 instances, resulting in substantial cost savings and reducing manual intervention.
Job 2: Deprovision organisations when license expires, ensuring compliance and reducing data retention in S3 and databases.
Enhanced the S3 deletion process to handle millions of files by implementing Kubernetes auto-scaling based on messages on an SQS queue, increasing throughput. This strategy was successfully adopted across other services.
Spearheaded Snyk vulnerability remediation across all repositories, improving overall security posture.
Actively contributed to DevOps improvements, including monitoring with Grafana, log analysis with InsightOps, and responding to incidents via PagerDuty on-call rotation.
Adapted into a full stack role (React js) to build and maintain an internal tool that enabled support engineers and product teams to monitor scans, EC2 instances, view debug logs and other valuable data, significantly improving customer issue resolution.
Worked closely with cross-functional teams including UX, Frontend, Platform, QA, Product Management to deliver high-quality solutions on time.
Mentored interns and junior engineers, providing guidance on code quality, testing and architecture.
Gained hands-on experience with AWS services, solidified by achieving the AWS Cloud Practitioner certificate and currently pursuing AWS Developer and Kubernetes KCNA certifications.
