Hiring Manager
Openkyber
Dear Hiring Manager,
Openkyber's recent push into serverless architecture aligns perfectly with the platform I have already built for Citibank, where I reduced deployment time from weeks to hours by migrating monoliths to AWS Lambda and DynamoDB. My experience designing resilient pipelines and orchestrating Kubernetes clusters across regions gives me the foundation to support your global user base.
At Citibank, I partnered with product teams to ship API features serving 2 million monthly users while maintaining PCI compliance; the security guardrails I implemented have become the standard for fintech launches.
Prior to that, I operated as a systems analyst with Capgemini, where I improved test coverage and observability on client projects across banking and retail verticals, instilling DevOps practices that reduced incident response times by 40%.
