💼 Work Experience

🚀 DevOps / AI Platform Engineer — TechNextGen, UK (Dec 2024 – Present)

Cloud-native AI platform modernisation — MLOps & platform engineering for enterprise AI workloads on multi-cloud.

  • Architected CI/CD/CT pipelines using GitHub Actions to automate LLM & GenAI model training, evaluation, packaging, and deployment on AWS SageMaker and GCP Vertex AI
  • Built and maintained Kubernetes (EKS) platform for AI/ML workloads — GPU scheduling, namespace isolation, RBAC, and Helm-based deployment patterns across dev/staging/prod
  • Leveraged GCP (Cloud Run, Cloud Functions, BigQuery, Cloud SQL) for scalable AI pipeline orchestration, reducing infrastructure overhead and improving MLOps throughput
  • Standardised platform observability using Prometheus, Grafana & Datadog with SLO-based alerting for model performance drift and pipeline failures
  • Authored Terraform & CloudFormation modules for EKS, VPCs, IAM roles, ALBs, and SageMaker workspaces — enabling self-service environment provisioning
  • Implemented FinOps controls: AWS Cost Explorer tagging, budget alerts, chargeback/showback dashboards, and reserved instance recommendations for AI GPU workloads
  • Integrated DevSecOps controls: Semgrep (SAST), SonarQube, SBOM generation, and AWS Secrets Manager for supply chain security

🏦 Azure DevOps Engineer — PwC Information Technology, UK (May 2023 – Nov 2024)

Delivery framework engineering for a UK Tier-1 bank — regulated CI/CD at scale, governance by design, and operational resilience.

  • Engineered enterprise-scale CI/CD pipeline frameworks using Azure DevOps & GitHub Actions — reusable YAML templates adopted by 20+ development teams, improving deployment frequency and reducing build time by ~40%
  • Implemented governance by design: protected branches, immutable artefact retention, approval gates, SoD controls, and audit trail logging aligned with FCA operational resilience requirements
  • Deployed and maintained Terraform-managed Azure landing zones — hub-spoke networking, Entra ID integration, RBAC, and environment separation (dev/uat/prod)
  • Automated Kubernetes (AKS) deployments using Helm and GitOps with Argo CD for drift detection — achieving 80%+ automated release coverage
  • Embedded DevSecOps controls: secret scanning, dependency auditing, SAST, DAST, container scanning, and policy-as-code guardrails (NCSC cloud security aligned)
  • Led observability standardisation: Prometheus, Grafana, and Azure Monitor alerting standards with on-call playbooks and rollback mechanisms, contributing to measurable MTTR reduction

🏥 DevOps Engineer — Elekta, UK (Aug 2022 – Apr 2023)

Cloud modernisation of Elekta Axis Cloud — Azure-hosted, security-first oncology informatics platform (regulated healthcare).

  • Delivered Azure cloud modernisation programme — designed Azure landing zones using Terraform (hub-spoke networking, AKS, Key Vault, ACR) replacing legacy on-premise infrastructure
  • Built and managed AKS container platform: cluster provisioning, namespace RBAC, Ingress (nginx/AGIC), TLS management, Helm chart standards, and Kubernetes upgrade runbooks
  • Established CI/CD pipelines for application and infrastructure delivery using Azure Pipelines — Terraform plan/apply gates, image scanning, and mandatory approval gates
  • Implemented DevSecOps controls for regulated healthcare: Key Vault integration, RBAC audit trails, controlled change processes, and pipeline-enforced compliance checks
  • Introduced monitoring stack (Prometheus, Grafana, Azure Monitor) with availability SLOs and incident response runbooks for critical oncology workloads

🌱 Junior DevOps Engineer — Bluesoft Technologies, India (Apr 2019 – Dec 2020)

DevOps foundations — CI/CD, environment automation, and Infrastructure as Code for multi-application delivery.

  • Designed and maintained CI/CD pipelines using Jenkins and GitHub Actions — reducing manual release effort and improving deployment consistency across teams
  • Provisioned and managed AWS infrastructure (EC2, VPC, IAM, S3, RDS, ALB) using Terraform and CloudFormation, eliminating configuration drift across dev/test/prod
  • Containerised workloads using Docker and deployed to AWS ECS/EKS — introduced Kubernetes-based deployment patterns for scalable application delivery
  • Wrote Bash and Python automation scripts for environment setup, deployment pipelines, and operational tasks — measurably reducing manual toil
