Gul Hussain Shah

I am an ASP.NET Core developer with four years of focused experience building ERP and CRM solutions for enterprise users. I deliver scalable, high-performance systems and prioritize reliability and maintainability.

I have designed and implemented comprehensive CRM and HRMS platforms, including lead generation, payroll (PDF/Excel), attendance tracking, shift and probation modules, and emergency call/ticketing systems. I built integrations with telephony systems, dialers, and third‑party APIs to automate workflows and improve operational efficiency.

My technical work spans C#, ASP.NET Core and Framework, Entity Framework, SQL Server, RESTful and SOAP APIs, XML, Azure, MongoDB, ElasticSearch, Docker, and Git. I focus on clean OOP, design patterns, real‑time reporting dashboards, and performant data access strategies.

I have worked as a team lead and freelancer in Agile environments, delivering end-to-end solutions and mentoring team members. I seek to join teams where I can continue improving enterprise systems, drive integrations, and take ownership of impactful features.
