Nujtech Ltd is the independent practice of Ravi Ramanuj, a platform engineer and DevSecOps specialist based in Manchester. The work spans cloud architecture, infrastructure, security posture, and the operational practices that tie them together.
Over ten years, Ravi has worked across a variety of companies and industries — from global enterprises to fast-moving SaaS organisations — taking full ownership of AWS estates, Kubernetes platforms, and end-to-end security and compliance programmes.
The focus is always on building things that are well-structured, secure by default, and simple to operate long-term.
A broad remit, covered in depth.
Full ownership of AWS platforms — from initial architecture and networking through to IAM, cost, and long-term operational design.
Cluster design, workload architecture, and full lifecycle management. Including migrations from legacy infrastructure and service mesh rollouts.
Security built into the delivery pipeline from the start — not added at the end. Vulnerability gates, image hardening, SAST, and policy-as-code.
Zero-trust IAM design, enterprise SSO rollouts, and federated AWS access. Credential hygiene and break-glass controls included as standard.
End-to-end visibility across infrastructure and services — logging, metrics, alerting, and SLO design. Built to be genuinely useful, not just present.
Structured Terraform estates, fleet automation, and CI/CD pipeline design — with a consistent emphasis on blast-radius reduction and clear change controls.
The tools used day-to-day, across ten years of production work.
A selection of measurable results from previous engagements, across security, reliability, cost, and operational maturity.
