Rawalpindi, Pakistan - 8:47 pm local time
As a full-stack developer specializing in Python, PHP, Laravel, and Node.js, I build backend systems that connect platforms, sync data, and run without constant babysitting. My focus areas include:
API Integrations & Backend Development
Custom REST/third-party API integrations, backend architecture, and system-to-system communication.
Business Process Automation
Turning manual, time-consuming workflows into automated systems including long-running jobs with resume/checkpoint functionality so nothing has to restart from scratch.
AI & OpenAI-Powered Workflows
Building AI-driven automation, chatbots, and intelligent data processing pipelines using OpenAI's API.
Web Scraping & Data Extraction
Reliable scraping systems for structured/unstructured data collection at scale.
Product & Inventory Synchronization
Recently built a full product sync system between NDK and Sellbrite handling thousands of SKUs, parent-child variation mapping, automatic category matching, and Sellbrite API uploads, with resume functionality for interrupted jobs.
Data Migration & Transformation
Moving and restructuring data between platforms, databases, and formats without data loss or downtime.
Tech stack: Python | PHP | Laravel | Node.js | MySQL | REST APIs | OpenAI API | Web Scraping
I write maintainable, well-documented code built to keep running long after the project ships. If you have a manual process draining your team's time, systems that need to talk to each other, or an idea that needs custom development — let's talk about how I can help.
