Accurate estimates. Transparent tracking. On-time delivery. No surprises.

I help teams build and improve Python backends for SaaS products and growing platform, whether that means starting an MVP from scratch or jumping into an existing codebase and making it better. Most of my work involves owning backend systems: reviewing code, fixing performance issues, migrating services, and making sure things stay stable as the product scales. I mainly work with Python, Django, FastAPI, and AWS, and I choose tools based on what actually fits the problem. Moreover, I have been working as a Python developer for 8+ years, supporting real production systems across different industries. I’m comfortable building new features, cleaning up legacy code, and handling the unglamorous but important work that keeps systems reliable. What I usually work on: Python backends using Django, FastAPI, and Flask SaaS platforms & MVPs (early builds → production) Microservice migrations and backend restructuring Code reviews, refactoring, and performance tuning APIs used by React and other frontends Databases like PostgreSQL, MySQL, and MongoDB Background jobs with Celery, Redis, and RabbitMQ Deployments and scaling on AWS Practical AI/ML features (NLP, chatbots, LLMs) when they make sense Key Projects: Touringery: Multilingual tour booking APIs → improved booking throughput by 50%. Moeving EV: Fleet tracking microservices → real-time data processing for 500+ vehicles. Kera Health: Backend for patient data, appointments, and AI diagnostics. Healthcare AI Diagnostics: Integrated ML models for automated patient reporting. Chatbot & NLP: Built intelligent NLP pipelines for customer support and internal knowledge management. I work well independently or with a team, communicate clearly, and take responsibility for the backend parts I touch. I’m available 40+ hours per week and can overlap with US and European time zones. If you’re looking for someone who can step into your backend and take ownership, "just click Invite", I usually reply within a few hours.

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.

I'm a Python backend developer with 3+ years of experience, currently working as a Team Lead at IFF Fund building QuwandiQ — an AI-powered trade journaling platform. My main focus these days is AI and RAG (Retrieval-Augmented Generation) — I build LLM-powered applications that actually work in production. Think AI support agents, smart chatbots, and multi-model backends using FastAPI. On top of that, I'm comfortable with the full backend stack: Django, PostgreSQL, Docker, AWS, and CI/CD pipelines. If you need someone who can bridge solid backend engineering with modern AI — let's talk.
