About Hamza
Senior Python Backend Developer | Django, FastAPI, React | ML & LLM Ap
Lahore, Pakistan - 7:56 pm local time
I am a Python backend-first developer with 8+ years of experience building scalable, high-performance backend systems using Python, Django, FastAPI, and Flask, integrating them with React.js and Next.js frontends when full-stack solutions are required. I design REST and RESTful APIs, GraphQL endpoints, microservices architectures, and secure, maintainable services around clean contracts and clear system boundaries. I implement authentication and authorization using OAuth, OAuth2, and JWT, harden APIs with validation, rate limiting, permissions, and secure secrets management, and optimize system throughput for production traffic.
I deliver AI integrations using OpenAI, LangChain, Composio, and other tool-based frameworks, embedding intelligent workflows into backend systems, web applications, and automation pipelines. I build Python-based automation and ETL pipelines, scheduled jobs, background queue processing using Redis, Celery, or RQ, and integrate them into production workflows to save teams hours weekly. For web scraping, I develop production-grade pipelines using Requests, HTTPX, BeautifulSoup, Scrapy, Selenium, and Playwright, cleaning, normalizing, and storing data into PostgreSQL, MySQL, or SQLite, then integrating it seamlessly into APIs, dashboards, reporting systems, or SaaS products.
I optimize database schemas, SQL queries, indexing strategies, and caching with Redis to ensure predictable scalability. I containerize applications using Docker, deploy on Linux servers, set up CI/CD pipelines with GitHub Actions, GitLab CI, or Azure DevOps, and manage cloud deployments on AWS, Azure, and GCP, including serverless architectures with Lambda and event-driven workflows for cost-efficient scalability. I focus on performance, security, and maintainability in every system I build.
Across industries including FinTech, Healthcare, E-commerce, PropTech, EdTech, AI SaaS, and CRM, my work has reduced API response times by 40–70%, improved database performance 3x, lowered cloud costs up to 30%, automated workflows saving $100K+ annually, and scaled SaaS products from MVP to 50K+ users.
If you want a Python developer who can own your product end-to-end—backend development, full-stack web applications, REST/RESTful and GraphQL APIs, database & SQL optimization, AI integrations, web scraping & automation, cloud deployment on AWS, Azure, or GCP, performance optimization, security, and scalable architecture—send me a message with your project and the outcome you want. I’ll provide a clear implementation plan with measurable results. ⚡
