Multi-cloud enterprise architecture

The systems Fortune 500 companies run on — built to last.

I'm Anuj Agrawal, a Technical Architect with 16+ years designing and modernizing enterprise platforms on Microsoft Azure and AWS — for healthcare networks where reliability is patient-facing, and energy companies where scale is non-negotiable.

Profile

Today I lead architecture across 50+ enterprise applications for Occidental Petroleum at HCLTech — multi-cloud systems spanning .NET, Java, and Python on Azure, AWS, and Terraform-based infrastructure-as-code.

Before that, I spent over a decade as the architectural backbone of Tenet Healthcare's consumer digital platform: consolidating 200+ microsites into one multi-tenant architecture serving 65 hospitals and 450+ facilities, with HIPAA, ADA Section 508, and WCAG 2.1 AA compliance designed in from day one — not bolted on.

Current focus

Championing AI-assisted engineering practices across delivery teams — code generation, review, and quality workflows — and authoring a practitioner's framework for post-quantum cryptography migration in enterprise multi-cloud environments, in preparation for submission to an IEEE practitioner publication.

Selected impact

~1M monthly visits

Architected the platforms behind Tenet Healthcare's revenue-generating consumer channels — online bill pay, paid classes and events, and patient scheduling — across 65 hospitals and 450+ facilities.

200+ sites, one platform

Led the consolidation of 200+ WordPress microsites into a unified Sitefinity multi-tenant platform — cutting release cycles 40% and deployment time 50%.

60% faster publishing

Raised content-publishing velocity 60% and mobile page-load performance 40% through template inheritance, reusable widgets, and relentless performance tuning.

10,000 assessments a day

Engineered SHL's SODA Core — a global 24/7/365 assessment platform serving 5,000+ clients across 130+ countries on distributed .NET.

15+ engineers mentored

Architecture reviews, code-quality standards, and hands-on mentorship across onshore and offshore teams — the multiplier behind every system above.
