Hi customer!!! 👋 I build web applications and AI platforms that handle real users at scale. Python and JavaScript are my primary languages, and I work across the full stack: React and Next.js on the frontend, Node.js and Express on the backend, MongoDB and PostgreSQL for data, and AWS for infrastructure. Over the past few years, I've shipped production systems that go well beyond standard CRUD apps. ◉ SimpleTalk is an AI voice and SMS platform I built that handles 1,800 simultaneous calls across 12 languages with CRM integrations and HIPAA-compliant infrastructure. ◉ Vikktoria is a legal AI platform serving 60,000+ users across 50 states and 30+ languages, built on AWS with Python backends and React frontends. ◉ SimZ involved full stack development with complex data flows and real-time processing requirements. My typical engagement looks like this: 👉 You describe the problem, I architect the solution, build it, deploy it on AWS (EC2, S3, Lambda, RDS, CloudFront), and hand you a system that runs without babysitting. 👉 I write clean, documented code because I've inherited enough undocumented projects to know what that costs downstream. What I work with daily: ➤ Python (Django, FastAPI, Flask), ➤ React, Next.js, ➤ Node.js, Express, MongoDB, PostgreSQL, ➤ REST APIs, GraphQL, ➤ AWS services, Docker, CI/CD pipelines, third-party API integrations (Stripe, Twilio, OpenAI), and WebSocket-based real-time systems. What clients say: 📌 "Abdul performed exceptionally. He understands the task well and works quick! Very knowledgeable and competent." 📌 "Despite the complexity of the work, he was always attentive and communicated closely with me to solve problems quickly and effectively. Our website's new UI/UX design has now been installed successfully. It looks and functions perfectly. I highly recommend selecting Muhammad for your project." If you have a web app, SaaS product, or AI integration that needs to be built properly the first time, send me the details. I'll tell you exactly how I'd approach it and what a realistic timeline looks like.
