At Stewart Pakistan, I migrated legacy on-premises systems into a cloud-native .NET 8 microservices ecosystem on Azure Kubernetes Service, improving scalability by 40%. I build asynchronous, event-driven data pipelines with Azure Service Bus and REST APIs that process more than 1.5 million daily payloads across North American FinTech platforms. I also strengthen production systems through OAuth 2.0, JWT, Azure Key Vault, and Application Insights. During my tenure at NETSOL Technologies, I optimized data retrieval by 30% by replacing heavy ORM queries with high-performance T-SQL and led enterprise leasing releases from impact assessment through production rollout. I’ve also delivered SOAP, REST integrations for Tier-1 banking clients.
