Asad S.

I help startups and enterprises design and build scalable backend systems, APIs, and cloud-based architectures using ASP.NET Core, microservices, and Azure DevOps pipelines. With 10+ years of experience in .NET development, I specialize in building high-performance, secure, and maintainable backend systems that power modern SaaS platforms, enterprise applications, and API-driven products. My focus is not just writing code — I design systems that are: ✔ Scalable under high traffic ✔ Secure and production-ready ✔ Easy to maintain and extend ✔ Optimized for cloud deployment I have delivered multiple enterprise-grade solutions including ERP systems, API platforms, and integrations with third-party services such as payment gateways, CRMs, and legacy systems. 🔧 What I Do Best Design and develop ASP.NET Core Web APIs Build microservices-based architectures Develop scalable SaaS backend systems Implement Azure DevOps CI/CD pipelines Database design & optimization (SQL Server, MySQL) Third-party API integration (payment, ERP, CRM systems) Legacy system modernization and migration 🏗 Core Expertise Backend Development ASP.NET Core, C#, Web API Entity Framework Core Clean Architecture / Onion Architecture Cloud & DevOps Microsoft Azure / AWS (deployment & hosting) Azure DevOps CI/CD pipelines Docker containerization Databases SQL Server MySQL Database optimization & performance tuning 💡 How I Work I follow a structured engineering approach: Requirement analysis & system design Scalable architecture planning Clean backend implementation Testing & optimization Deployment & CI/CD automation My goal is to deliver systems that don’t just work — they scale and last long-term in production environments. 📌 Optional Full-Stack Capability When required, I also build modern frontend interfaces using: React.js Angular HTML/CSS/JavaScript However, my core specialization remains backend architecture and API systems. 🏆 Experience Summary 10+ years in .NET ecosystem Delivered enterprise ERP and SaaS systems Built API-driven applications and integrations Worked on full lifecycle development (design → deployment) Experience in both startups and enterprise environments 🤝 Let’s Work Together If you are looking for a developer who can build robust backend systems, scalable APIs, or cloud-ready applications, I can help you turn your idea into a production-ready solution. Let’s build something reliable, scalable, and future-proof.
