Publicis Sapient
10.2021 - Current
- Led infrastructure migration across Azure regions using Terraform, achieving zero-downtime cutovers and full HA/DR compliance for 10+ production workloads.
- Designed and delivered Infrastructure as Code (IaC) solutions using Terraform, provisioning 100+ Azure and GCP resources per release cycle, reducing manual provisioning effort by ~70%.
- Implemented GitOps workflows using ArgoCD, enhancing automated application delivery across Dev, QA, UAT, and Prod environments with full audit trails.
- Built and maintained multi-stage CI/CD pipelines using Azure DevOps YAML, improving deployment frequency from bi-weekly to daily and cutting release lead time by 40%.
- Managed Kubernetes (AKS & GKE) application deployments via Helm charts, supporting 20+ microservices with consistent rollout automation and rollback capability.
- Integrated Azure Key Vault with AKS clusters for centralised secret management, eliminating hardcoded credentials across all deployment pipelines.
- Provisioned DR environments with Terraform, achieving RTO < 1 hour and RPO < 15 minutes for critical workloads.
- Designed Hub-and-Spoke network topology for enterprise cloud architecture, strengthening security isolation and minimising blast radius of incidents.
- Implemented full-stack observability using Prometheus and Grafana dashboards with custom alerting rules, defining SLA/SLO targets and reducing MTTD by ~50%.
- Designed and integrated asynchronous messaging solutions using RabbitMQ and Apache Kafka, decoupling microservices and enabling resilient event-driven communication.
- Managed Docker Swarm clusters for legacy workload orchestration during Kubernetes migration phases, ensuring zero service disruption across multi-node swarm deployments.
- Automated routine infrastructure operations with Python SDKs, saving ~8 hours/week of manual operational effort.
- Collaborated with development, security, and architecture teams to implement DevSecOps best practices across the SDLC.
- Authored HLD and LLD documentation for infrastructure, networking, and deployment architectures, enabling smooth onboarding for 5+ team members.
- Designed and maintained Azure DevOps pipelines for .NET applications, integrating NuGet private artifact feeds for internal package distribution and version management across 5+ .NET solution repositories.
- Implemented automated quality gates in .NET CI pipelines using NUnit test suites and NSubstitute mocking framework, enforcing minimum code coverage thresholds before merge and achieving 85%+ test pass rate on PRs.
- Configured multi-stage .NET build and release pipelines in Azure DevOps with environment-specific configuration transforms, automated NuGet restore, build, test, and containerised publish stages.
