What I'm looking for

I’m looking for a team where I can own backend services end-to-end, lead microservice architecture, improve reliability and performance, and raise engineering delivery through CI/CD automation—while mentoring others and partnering across teams.

I’m a software engineer at CGI focused on building and owning core backend services with Java and Spring Boot. In my role, I took end-to-end responsibility for a core order-management service—owning the roadmap and SLAs—while influencing sprint prioritization across a 7+ engineer pod.

I drive architectural decomposition from monoliths to independent microservices, improving fault isolation by ~30% and containing failure blast radius at scale. I also optimize hot-path performance by restructuring ORM mappings and rewriting critical SQL with execution-plan-guided indexing (boosting throughput ~20% and reducing P95 latency), lead structured post-mortems to cut repeat incidents by ~25%, and spearhead CI/CD automation (Jenkins/GitHub Actions) to reduce deployment cycle time by ~40%. I mentor junior engineers through live defect triage and design walkthroughs, conduct 10+ technical interviews, and earned two CGI Bronze Awards for engineering excellence.
