About Abdullah Al
ASP.NET Core Expert | Custom Business Software | APIs | SQL Server Opt
Dhaka, Bangladesh - 1:28 am local time
I’m a Senior Full Stack .NET Developer specializing in building scalable, secure, high-performance, and maintainable software solutions for real-world business environments.
I work across the complete software development lifecycle—from requirements analysis, database design, architecture, backend/API development, frontend implementation, testing, performance optimization, deployment, and production support.
My core expertise includes C#, .NET, ASP.NET Core, ASP.NET MVC, Web API, WebForms, Entity Framework Core, ADO.NET, LINQ, SQL Server, REST APIs, React, Next.js, JavaScript, and TypeScript.
🚀 What I Do
✔ Build scalable enterprise web applications
✔ Develop secure ASP.NET Core Web APIs and REST services
✔ Create React/Next.js dashboards and business portals
✔ Optimize SQL Server databases and slow queries
✔ Modernize legacy ASP.NET WebForms and .NET Framework systems
✔ Design ERP, WMS, CRM, inventory, procurement, HR, finance, and logistics systems
✔ Integrate third-party APIs and external services
✔ Troubleshoot production issues and performance bottlenecks
✔ Implement authentication, authorization, and role-based security
✔ Deploy applications using IIS, Windows Server, Azure, AWS, and Docker

* Legacy frontend modernization
🗄️ SQL Server & Performance Optimization
Database and application performance are key areas of my expertise.
I work with SQL Server, T-SQL, stored procedures, views, functions, CTEs, execution plans, indexing, query optimization, deadlock/blocking analysis, data migration, and large-volume processing.
I investigate performance across the complete stack:
Frontend → API → Business Logic → Data Access → SQL Server → Infrastructure
I optimize slow queries, inefficient stored procedures, missing indexes, N+1 queries, excessive database calls, inefficient EF Core queries, slow APIs, memory/CPU consumption, and large data-processing workloads.
My approach is data-driven: identify → measure → optimize → verify.
🏢 Enterprise Application Development
I specialize in business systems including:
* ERP & Business Management Systems
* Warehouse Management Systems (WMS)
* Inventory Management Systems
* Procurement Management Systems
* CRM Platforms
* Financial & Accounting Systems
* HR Management Systems
* Healthcare Applications
* Education Management Systems
* Logistics & Supply Chain Platforms
* Reporting & Analytics Dashboards
* Workflow & Approval Systems
* Customer & Administration Portals
I focus on understanding the complete business workflow before designing the technical solution.
🏗️ Architecture & Engineering
I use proven architectural principles based on project requirements and complexity:
* Clean Architecture
* Onion Architecture
* Layered Architecture
* Vertical Slice Architecture
* Feature-Based Architecture
* Domain-Driven Design (DDD)
* CQRS
* SOLID Principles
* Design Patterns
* Modular Architecture
* Event-Driven Architecture
* Microservices
I avoid unnecessary complexity and select architecture based on maintainability, scalability, performance, and business value.
🔄 Legacy Modernization
I help businesses modernize existing applications while protecting critical business logic:
* ASP.NET WebForms → ASP.NET Core
* .NET Framework → Modern .NET
* Legacy VB/.NET modernization
* Monolith refactoring
* Legacy database optimization
* API extraction
* Authentication modernization
* Frontend modernization
* Incremental migration strategies
My goal is to improve architecture, security, performance, and maintainability while minimizing business disruption.
☁️ Cloud, DevOps & Production
Experience includes Azure, AWS, IIS, Windows Server, Docker, CI/CD, deployment, logging, monitoring, Redis, Azure Service Bus, Kafka, background workers, distributed caching, retry/resilience strategies, Outbox Pattern, and Saga Pattern.
🔐 Security
I implement secure application practices including JWT, Identity, RBAC, OAuth 2.0, OpenID Connect, secure API design, validation, authorization, and secure data access.
Why Work With Me?
I don't just write code—I focus on solving the underlying business and technical problem.
Let's build software that performs reliably today and scales confidently tomorrow.
