Mayank Kumar

Cloud SRE and DevSecOps Engineer with 7+ years designing, securing, and scaling mission-critical infrastructure across fintech, financial services, and telecom. Combines multi-cloud automation (AWS, Azure, GCP) and Kubernetes-based orchestration with full-lifecycle CI/CD engineering across GitLab, Jenkins, Harness, and CircleCI to ship zero-downtime Blue-Green and Canary releases. Builds end-to-end observability programs spanning Datadog, New Relic, Prometheus, Grafana, ELK, Site24x7, Papertrail, and SolarWinds that drive on-call response, postmortem discipline, and measurable gains in uptime and MTTR.

Track record of cutting deployment times by up to 60%, lifting system uptime by up to 30%, and embedding SonarQube/Checkmarx security gates into every release pipeline. Currently expanding into Go and AI/LLM-driven infrastructure automation.
