Code Fix for Incomplete Project
We had an incredible experience with Haris. He completed our two week projected project in three days with enhancements. We will definitely be using him again and anyone would be lucky to have him. He understood everything and asked for clarification when needed, no guess work. He was very thorough and an incredible communicator.

Job Success
Karachi, Pakistan - 7:30 pm local time
I hold both the DP-600 and DP-700 Microsoft Fabric certifications — a combination held by fewer than 1,000 people globally
Why clients choose me:
Data pipeline expertise: Microsoft Fabric certified (DP-600 & DP-700), designing ETL/ELT pipelines, Power BI dashboards, and Azure-based data solutions.
Speed without compromise: Delivered an AI-powered restaurant map MVP in record time (Dec 2024).
Long-term reliability: Managed ongoing contracts worth $11,595+ (464 billable hours with one client).
Complex problem-solving: Integrated ChatGPT APIs, translated Python to TypeScript, and built full-stack MERN applications with seamless AWS/Azure deployments.
Team leadership: Led frontend teams and managed cross-functional API integration projects.
Recent client feedback:
"Incredible speed and communication! Built the MVP I was looking for in record time."
"Haris is an amazing developer with excellent communication skills... extremely passionate and knowledgeable."
"The best freelance developer I have EVER worked with."
What I deliver:
✅ Data solutions: ETL/ELT pipelines, Power BI dashboards, Microsoft Fabric, SQL optimization, data transformation
✅ Cloud architecture: Azure (Synapse, Data Factory, Function Apps) & AWS (Lambda, S3, Cognito)
✅ AI/ML integration: OpenAI, Gemini, custom chatbots, intelligent automation
✅ Full-stack web applications: React, Next.js, Python, Node.js — production-ready and scalable
✅ API development: RESTful APIs, third-party integrations (Stripe, Maps, Firebase)
My full-stack background means I don't just build pipelines — I understand the applications consuming the data. That means fewer integration headaches, cleaner architecture, and faster delivery.
My process: I solve business problems, not just write code. I'll understand your scope deeply, communicate proactively, and deliver clean, maintainable work that scales.
No big claims — just honest, expert execution within your budget. Let's talk.

Requirement Gathering

Design and Mockup (Optional)
After finalizing the requirements, I will create a design and mockup to visualize the application's look and feel. We’ll work together to refine the design through iterations until we achieve the ideal user experience.
