About Zafar

Zafar A.Status: Offline
Senior .NET Engineer | Backend APIs, AI Integration & Modernization
5.0  (1 review)
Karachi, Pakistan - 4:49 am local time
I am a senior full-stack engineer with 15+ years of experience building backend systems, REST APIs, and AI-powered applications. My most recent work is Softyze, a self-hosted platform I designed and built solo that turns any business dataset into a secured REST API, auto-generated web page, and admin dashboard with AI schema inference. That's the level of ownership I bring to client projects.

Most of my work falls into three categories: building new backend systems from scratch, modernizing legacy applications that need to scale, and adding intelligent features using modern AI tools.

WHAT I BUILD

Backend Systems & APIs
- REST APIs with proper documentation, authentication, and error handling
- Database-driven web applications (SQL Server, PostgreSQL, MongoDB)
- Microservices architecture and service integration
- Payment gateway and third-party API integrations
- Enterprise-level intranets and content management systems

AI Integration (Practical, Production-Ready)
- ChatGPT/OpenAI API integration for customer-facing features
- Intelligent automation and workflow enhancement
- AI-powered search, summarization, and content processing
- Cost-conscious AI implementation that scales responsibly

System Modernization
- Refactoring legacy .NET Framework applications to .NET Core
- Performance optimization for slow or unstable systems
- Database query optimization and architecture improvements
- Security hardening (authentication, authorization, data protection)
- Technical debt reduction without breaking existing functionality

TECHNICAL ENVIRONMENT

Core: .NET Core, ASP.NET Core, C#, Entity Framework
Databases: SQL Server, PostgreSQL, MongoDB
Cloud: Azure, AWS
APIs: RESTful design, OpenAPI/Swagger, JWT authentication
Frontend: HTML/CSS/JavaScript, jQuery, React/Next.js
AI/ML: OpenAI API, ChatGPT integration, AI workflow automation

HOW I WORK

I start every project by understanding your business problem, not just the technical requirements. From there, I focus on solutions that are:
- Maintainable (your team can work with the code after I'm done)
- Stable (production-ready, not proof-of-concept quality)
- Documented (clear enough that you're not dependent on me long-term)

Clients typically hire me when they need someone who can work independently, communicate technical decisions clearly, and deliver systems that keep working after the contract ends.

Whether you are building something new, fixing something broken, or adding modern AI capabilities to an existing application, I am happy to discuss your project and see if it's a good fit.
