You will get PostgreSQL Database Engineer | Backend, ETL Pipelines & PostGIS | AWS GCP
Project details
I am a PostgreSQL database engineer specializing in backend database development, ETL pipelines, cloud deployment (AWS/GCP), performance optimization, and PostGIS spatial systems.
━━ WHAT I DO ━━
• Database design (schemas, relationships, constraints, indexing)
• Complex SQL (joins, CTEs, window functions, optimization)
• ETL pipelines (Python, APIs, CSV/JSON, automation, scheduling)
• Performance tuning (EXPLAIN ANALYZE, indexing, partitioning)
• Cloud deployment (AWS RDS, GCP Cloud SQL, Docker, Supabase)
• PostGIS spatial data (parcels, zoning, GeoJSON, shapefiles)
━━ KEY SKILLS ━━
PostgreSQL · PostGIS · Python · SQLAlchemy · Node.js · FastAPI · AWS · GCP · Airflow · Docker · GeoPandas · QGIS
━━ DELIVERABLES ━━
• Production-ready database schemas
• ETL pipeline scripts
• Optimized SQL queries
• Cloud deployment setup
• Documentation + data models
• Performance tuning reports
I build scalable, production-grade database systems from scratch or improve existing ones for speed, reliability, and cloud readiness.

About Waqas
Data Engineer | Python | PostgreSQL | AWS | ETL | Scraping | USA DATA
Islamabad, Pakistan - 4:47 am local time
I help companies collect, clean, structure, and scale data using Python, PostgreSQL/PostGIS, AWS, ETL pipelines, and advanced web scraping automation. My goal is always automation, consistency, and clean, production-ready solutions that your team can actually use.
What I Can Do for You
✅ Design and build end-to-end automated ETL data pipelines
✅ Integrate disparate data sources — APIs, websites, files, databases
✅ Set up and maintain SQL databases (PostgreSQL, PostGIS)
✅ Deploy services and APIs in the cloud (AWS, Docker)
✅ Develop RESTful APIs for data delivery
✅ Data Mining and Web Scraping (Python, BeautifulSoup, Scrapy, Selenium, Playwright)
✅ Set up CI/CD pipelines (GitHub Actions, Jenkins) for reliable releases
✅ Containerize applications for smooth, portable deployment
✅ Process and engineer complex GIS and geospatial datasets
✅ Build USA property, parcel, permit, zoning, and real estate data systems

Why Clients Hire Me
I don't just write scripts — I build usable data systems.
That means I help clients collect the right data, clean and structure it properly, store it in the right schema, validate quality, automate refreshes, and deliver it in a format their team can actually use.
Whether your project involves business data pipelines, web scraping at scale, cloud automation, or large-scale USA real estate and GIS datasets, I build reliable, maintainable solutions from day one.
Send me a message with your data source, target output, and business goal, and I'll help you map out the right workflow.
Steps for completing your project
After purchasing the project, send requirements so Waqas can start the project.
Delivery time starts when Waqas receives requirements from you.
Waqas works on your project following the steps below.
Revisions may occur after the delivery date.
Project Scoping & Requirements Review
I review your current database situation, stack, data types, and goals — then define the full project scope, architecture plan, and timeline before any work begins. You will know exactly what I am building and why.
Schema Design & Database Architecture
I design a clean, normalized PostgreSQL schema with proper table relationships, foreign keys, constraints, indexes, and JSONB modeling where needed. Every design decision is documented with an ER diagram and data dictionary.
