I architectcloud platforms thatscale, stay secure,and ship faster.
I'm J Ntongwe — a Senior Azure Cloud Architect & DevOps Engineer with 8+ years turning sprawling enterprise stacks into resilient, automated platforms. Currently architecting cloud at Hiscox.
Cloud platforms, end to end.
From migrating legacy workloads into Azure to building Kubernetes platforms that survive Black-Friday-scale spikes — I work across the full surface area of a modern cloud organization.
Cloud Architecture
Enterprise Azure & hybrid designs across IaaS, PaaS, and SaaS — built for scale, cost-efficiency, and resilience.
DevOps & CI/CD
Azure DevOps, GitHub Actions, Jenkins. Blue/green, canary, GitOps. Pipelines teams actually trust.
Infrastructure as Code
Terraform, Bicep, ARM, Ansible. Reproducible environments and zero-drift platforms from dev to prod.
Containers & Kubernetes
AKS, Docker, Istio, ACR. Microservices that scale horizontally and recover automatically.
Security & Identity
Entra ID, RBAC, Key Vault, OAuth/OIDC, Sentinel. Defence-in-depth without slowing delivery.
Networking
VNets, Application Gateway, Front Door, ExpressRoute, Private Endpoints — secure connectivity at scale.
Data Platforms
Azure SQL, Cosmos DB, Data Lake, Databricks, Data Factory. Pipelines that move data reliably.
Observability
Azure Monitor, App Insights, Prometheus, Grafana, ELK, Splunk. Know before users do.
A repeatable path from chaos to platform.
Discover
Audit current architecture, workloads, costs, and security posture. Identify the highest-leverage moves.
Design
Target architecture, landing zones, networking and identity blueprints — reviewed with engineering and security.
Automate
Terraform/Bicep modules, CI/CD pipelines, golden images. Every environment becomes reproducible.
Migrate
Phased cutovers using Azure Migrate, Site Recovery, and zero-downtime patterns. Rollback plans always ready.
Operate
Observability, runbooks, SLOs, on-call. Continuous cost and reliability tuning post launch.
Eight years, five teams, one obsession.
Senior Cloud Architect & DevOps Engineer
Leading enterprise-scale Azure architecture across SaaS/PaaS/IaaS for business-critical insurance workloads.
- Architecting AKS-based microservices with Istio, Prometheus, Grafana
- IaC at scale with Terraform, Bicep, ARM via Azure DevOps
- Entra ID, OAuth/OIDC, SAML, Key Vault — enterprise security baseline
- Multi-region DR with Site Recovery and Azure Backup
- Integrated Azure OpenAI & AI Services for intelligent automation and document processing
A deep stack, not a buzzword bingo.
Every tool here is something I've shipped to production — usually under heavy load, often under compliance, always with someone on-call.
Senior architecture and platform-engineering work — Azure migrations, AKS platforms, IaC rollouts, DevOps modernization, and security uplifts. I'm comfortable embedded with a team or leading a discrete initiative end-to-end.
Azure is my deepest stack (7+ years), but I've shipped serious AWS workloads too and design hybrid architectures regularly. The patterns transfer; the levers don't.
Yes — I've worked in insurance, banking, and healthcare. Encryption at rest/in transit, secrets management, RBAC, Sentinel monitoring, SOC-ready audit trails are part of the default playbook.
All three. I'm based in Austin, TX, and have led distributed teams across North America. Time-zone overlap and a clean async cadence usually matter more than a chair location.
Lead time to deploy, change-failure rate, MTTR, cost per workload, and platform NPS from the engineers using it. If those move, the business outcomes follow.
Have a cloud problem that won't sit still?
Whether it's a migration that's stalled, a Kubernetes platform you want to take seriously, or a DevOps practice that needs to mature — let's talk.
