What I'm looking for

I am looking for a role combining DevOps and full-stack responsibilities where I can improve CI/CD, architect cost-effective cloud systems, mentor teams, and deliver scalable, secure solutions.

I am a software engineer and DevOps professional with three years' experience building automated deployment pipelines, resilient AWS architectures, and full-stack applications. I focus on improving release velocity and system reliability through CI/CD, IaC, containerization, and monitoring.

I have led cross-functional teams to build payment gateways and remittance platforms serving multiple countries, and I architect cost-effective production environments using Lambda, DynamoDB, S3, Cognito, ECR, Docker, Kubernetes, and Terraform. My work has cut deployment time by 50%, improved incident response and system visibility by 50%, and maintained uptime above 90% in production environments.

I seek roles where I can combine full-stack development strengths with DevOps best practices to design secure, scalable, and maintainable systems while mentoring teams and driving measurable operational improvements.
