💡 The Problem Enterprises Face
Legacy workflows that slow down business agility
APIs without governance, creating security & compliance risks
Manual processes draining time & resources
Integrations that don’t scale with growth
🔧 The Solutions I Deliver
Using Microsoft Azure Integration Services, I design and deliver solutions that solve these challenges head-on:
Azure Logic Apps & Functions – automation, event-driven design, secure workflows
API Management (APIM) – enterprise API governance, OAuth2, JWT, IP filtering, and custom policies
Event-driven Systems – real-time processing with Event Grid & Service Bus
Infrastructure-as-Code – repeatable, secure deployments using Bicep & ARM
DevOps Automation – CI/CD pipelines with GitHub Actions & Azure Pipelines
📈 The Results My Clients Achieved
✔ World Bank – Designed secure, SAP-integrated microservices on Azure App Service (Isolated Plan), meeting strict compliance standards
✔ AvidXchange (USA) – Automated document workflows with Logic Apps & Azure Functions, using OAuth-secured integrations
✔ Genting Casinos (UK) – Built real-time identity validation & audit system with Event Grid, Cosmos DB & Functions, complete with observability pipelines
✔ Global Enterprises – Migrated legacy Java/.NET workflows into modern, serverless architectures with enterprise DevOps
