Muhammad A.

I help teams build and improve Python backends for SaaS products and growing platforms, whether that means starting an MVP from scratch, integrating AI capabilities, or improving an existing production system. Most of my work involves owning backend systems: reviewing code, fixing performance issues, migrating services, designing scalable APIs, and making sure applications stay stable as they grow. I mainly work with Python, Django, FastAPI, Flask, and AWS, while selecting the right architecture and tools based on the actual business problem and computer vision solutions for image processing, detection, and AI-based analysis and AI/ML integrations including LLM applications, RAG pipelines, NLP systems, and intelligent automation. 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, integrating AI/ML solutions, and handling the important engineering 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 REST API development and third-party integrations Code reviews, refactoring, and performance optimization Databases like PostgreSQL, MySQL, and MongoDB Background jobs with Celery, Redis, and RabbitMQ Deployments and scaling on AWS AI/ML integrations including LLM applications, RAG pipelines, NLP systems, and intelligent automation Computer Vision solutions for image processing, detection, and AI-based analysis 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: Healthcare backend handling patient data, appointments, and AI-powered diagnostics. Healthcare AI Diagnostics: Integrated ML models for automated patient reporting and intelligent insights. AI Chatbots & NLP Systems: Built LLM-powered conversational solutions, knowledge retrieval systems, and AI automation workflows. I work well independently or with a team, communicate clearly, and take ownership of the backend and AI systems I build. 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, improve your systems, and build scalable AI-powered solutions, "just click Invite" I usually reply within a few hours.
