Daniel Ali

Architected and implemented RESTful API endpoints and backend services using ASP.NET Core, with clear contract definitions, input validation, and consistent error handling to support multi-web and desktop clients. Designed microservice integration patterns with Azure Service Bus and RabbitMQ for asynchronous workflows; introduced Redis-based caching to reduce dashboard read latency and support real-time feeds. Built CI/CD pipelines in Azure DevOps with multi-stage deployments to Azure VMs and App Services; tuned multithreaded components for market data throughput. Implemented token-based authentication, role-based authorization, and input sanitization; led API security design with OpenAPI/Swagger. Drove observability with structured logging and metrics; integrated Prometheus/Grafana; authored unit/integration tests; mentored junior engineers and collaborated with frontend teams.

Designed and implemented backends using .NET Core and ASP.NET Core Web API, with modular controllers, service layers, and repository abstractions. Built microservices with bounded contexts and CQRS where appropriate to separate read/write workloads. Implemented data access strategies with MS-SQL, T-SQL stored procedures, and EF Core with careful transaction boundaries. Integrated asynchronous messaging with Azure Service Bus and RabbitMQ to decouple services and support background processing for orders and billing. Established CI/CD workflows in Azure DevOps and Docker with multi-stage pipelines and gated deployments to staging/production. Introduced NUnit-based tests and service-level health checks; documented endpoints with OpenAPI/Swagger. Mentored engineers on system design and clean architecture.

Developed full-stack features for multi-tenant applications using C#, ASP.NET Core, EF Core, and React; applied domain-driven design and clean architecture to improve maintainability and cross-team delivery. Implemented event-driven integrations and background workers for subscription migrations and cross-tenant data synchronization. Configured Azure resources (Blob Storage, Service Bus, Cosmos DB) for storage, messaging, and scalable persistence. Built real-time notifications with SignalR/WebSockets; authored automated tests; introduced Docker-based CI pipelines for deployments. Contributed to onboarding materials and mentoring of junior engineers.
