Hiring Manager
Codem Inc.
Dear Hiring Manager,
Codem's commitment to reliable, scalable systems resonates with the safety-critical engineering I have led in India. At WSP, I designed and oversaw microservices that reduced incident reporting cycles by 40%. My background in regulated environments means I build with compliance and reliability as first principles.
I have extensive experience with AWS, Kafka, and Java, having migrated legacy applications to cloud-native architectures while ensuring compliance with safety standards. The pipelines I built reduced deployment times by 60% without compromising our audit requirements.
Collaboration across disciplines is central to my approach. I regularly facilitate workshops with compliance, operations, and engineering teams to align technical roadmaps with regulatory expectations and operational realities.
