Deploy a simple containerized web app on AWS within 2 hours.
Khalil did an outstanding job deploying our containerized app on AWS. He quickly set up the infrastructure using Terraform and ECS Fargate, and the CI/CD pipeline via GitHub Actions worked perfectly. Everything was well-documented, and the app was live within hours. The deployment was smooth, and all requirements were met with precision. Highly recommend Khalil for any DevOps or cloud deployment work!

Python Automation & Scraping Expert | I Build Bots That Save Businesse

Job Success
Lahore, Pakistan - 3:20 am local time
I'm Khalil Raza — a Python backend developer with 7+ years of experience building web scrapers, automation systems, APIs, and data pipelines that solve real business problems.
Most of my work comes down to one thing: replacing slow, manual, error-prone processes with fast, reliable, automated ones. Whether that's collecting data from websites at scale, automating a workflow that eats hours every day, or building a backend API that needs to hold up in production — I focus on solutions that actually work long-term.
✔ Web Scraping & Data Extraction
Scrapers that handle anti-bot protection, CAPTCHAs, pagination, and proxy rotation — built with Playwright, Selenium, Scrapy, and BeautifulSoup.
✔ Automation Bots & Workflow Automation
End-to-end bots that replace repetitive manual work: price monitors, lead collectors, report generators, notification systems.
✔ REST API Development
Production-grade APIs with FastAPI, Flask, and Django — with auth, rate limiting, and clean architecture built to scale.
✔ Third-Party Integrations
Stripe, Twilio, SendGrid, Google APIs, Slack — I connect your tools so your systems work together without manual handoffs.
✔ Data Pipelines & Storage
PostgreSQL, MySQL, MongoDB, Redis — structured pipelines that store, clean, and deliver data reliably.
✔ Cloud Deployment
AWS EC2, S3, Docker — I deploy and maintain what I build. The job isn't done until it's running in production.
━━━━━━━━━━━━━━━━━━━━━
Projects I've delivered:
━━━━━━━━━━━━━━━━━━━━━
• E-commerce scrapers collecting 50,000+ product listings daily with anti-bot handling and proxy rotation
• Lead generation automation that eliminated hours of daily manual research for a sales team
• FastAPI SaaS backends with JWT auth, Stripe billing, and AWS deployment
• Real-time price monitoring systems with automated alerts
• Automated reporting pipelines that replaced manual data entry workflows entirely
━━━━━━━━━━━━━━━━━━━━━
Clients come back because I communicate clearly, ask the right questions before writing a single line of code, and respond within 4 hours. I write for production — not just to pass a demo.
If you have a project involving scraping, automation, APIs, or backend systems, send me an invite with your requirements. I'll review it and tell you honestly within 24 hours whether I'm the right fit — and exactly how I'd approach it.
