Architected and operate cloud-native GCP infrastructure for a multi-tenant SaaS platform processing 150K+ customer reviews/month, owning environments end-to-end. ● Provisioned all infrastructure via Terraform: GKE workloads, Cloud Run serverless, and Pub/Sub event-driven pipelines, with Bash and Python scripting for release automation. ● Built zero-downtime CI/CD pipelines with automated rollback across production and staging — zero deployment incidents to date. ● Enforced IAM, Secret Manager, and VPC hardening across all customer environments, alongside ongoing server and configuration management. ● Delivered a full observability stack (Prometheus, Grafana, ELK) supporting 30+ third-party integrations at 99.9% uptime SLA. ● Translated infrastructure trade-offs into plain-language updates for non-technical founders, directly supporting product and roadmap decisions.

Achieved a 28% reduction in cloud carbon emissions and 25% cost savings via carbon tracking and workload right-sizing, benchmarked against the client's prior 12-month spend. ● Built CI/CD pipelines (GitHub Actions + Docker) that halved deployment times and lifted delivery velocity by 60%. ● Automated infrastructure as code with Terraform and Kubernetes, cutting provisioning time by 50% and human error rate by 40%. ● Configured Nginx as reverse proxy and load balancer across staging and production to support the carbon-tracking dashboard's traffic scaling.

Led microservices orchestration on AWS EKS and OpenShift, including service mesh configuration, enabling scalable, resilient deployments. ● Designed enterprise-grade CI/CD pipelines using GitHub Actions and Octopus Deploy, improving deployment frequency by 40% against the prior manual release cadence. ● Automated infrastructure provisioning with Terraform and CloudFormation; implemented GitOps and configuration management practices across the full deployment lifecycle. ● Built and maintained developer tooling: quality gates, testing framework integration (SonarQube), and on-call runbooks for safe self-service deployment. ● Collaborated cross-functionally with product and QA teams, mentoring a junior engineer through their first production deployment cycle.

Containerized applications with Docker and deployed on AWS, cutting cloud costs by 25%. ● Built Node.js/Express microservices handling 20K+ RPM, optimized with Redis caching, reducing latency by 40%. ● Deployed and managed monitoring using CloudWatch, Prometheus, and Nagios, with custom alerting dashboards for system administration teams.
