Senior Software Engineer Current
Responsible for end-to-end operational stability for 400+ critical banking APIs and 5 standalone legacy applications hosted on AWS and RedHat OpenShift. The product ecosystem spans core banking verticals: Mortgages, Secured & Unsecured Lending, Debit Cards, and Credit Cards.
Key Accomplishments & Responsibilities:
- Multi-Cloud Infrastructure: Used Terraform to efficiently deploy, scale, and monitor infrastructure across multi-cloud applications (AWS, RHEL OpenShift, Private Cloud).
- Automated Live Proving: Authored custom automated verification scripts to execute "live proving" of APIs immediately following production deployments.
- Observability & Alerting: Developed custom AppDynamics and ELK alerting logic for APIs and database queries, drastically reducing Mean Time to Detect (MTTD).
- Performance Health Check Dashboard: Built an integrated health dashboard monitoring the underlying process load of client servers in real time.
- PRR & Governance: Led Production Readiness Reviews (PRR) and SOM Jira release gates, ensuring flawless deployments with zero unscheduled downtime.
- Team Leadership: Spearheaded a team of 4 engineers, driving technical design flow, estimation, and successful delivery of high-impact automation tools for client workflows.
- AI-Assisted Efficiency: Integrated GitLab Duo and Microsoft Copilot to optimize BAU operations and accelerate scripting productivity.
Member Technical – COS R&D
