Ahmed R.

I build data-driven software: the data pipelines, the web and mobile apps on top, and the AI automation that makes them smarter. GIS and location data is my specialty. I use Claude and GPT models to add features like natural-language search, document and data extraction, and AI assistants inside the apps I deliver. Most projects stall between the data and the finished product. I handle both sides: spatial and tabular data engineering, and the full application layer, deployed on AWS. WHAT I DELIVER 1. Data Engineering - ETL and data pipelines (Python, PostgreSQL / PostGIS, AWS RDS and S3) - Large-scale spatial and raster data processing and performance tuning - Dashboards and real-time analytics on big datasets 2. Data Science and GeoAI - Spatial clustering, route optimization and predictive analysis - Remote sensing and geospatial analytics (Google Earth Engine, QGIS, ArcGIS) - GeoAI and digital-twin style urban analytics 3. Software Development - Web apps and portals: React, Node.js / Express, Django, REST APIs - Web GIS: Mapbox, Leaflet, OpenLayers, Cesium (3D tiles, point clouds) - Multi-role platforms with authentication and workflows 4. Mobile Apps - iOS and Android apps with React Native - Map-based apps: tracking, routing, field data collection 5. AI Automation - AI features built on the Claude API and OpenAI GPT API: chat assistants, summarisation, data extraction and classification - Custom GPTs and GPT Actions connected to your own data, maps and APIs - Voice and location-based AI assistants - Workflow and data-processing automation with LLM APIs (Claude, GPT) and Python or Node.js - AI-assisted development with Claude and GPT, so I ship faster without lowering quality. RECENT WORK (live links in my Portfolio) - ZaraatConnect: farmland map portal for Pakistan with soil, crop and weather data - Alertli: voice and location-based AI guide, live on web and Android - PadelBro: matchmaking and community app for web and mobile - FEMA Elevation Certificate web app and a real-time GIS analytics dashboard on AWS - Mobile route and event planner for a Houston-based client (5.0 rating) WHY CLIENTS WORK WITH ME - Master’s in Remote Sensing & GIS, 6+ years of production experience - Clear scope, regular updates, replies within hours - I build for the decision the data needs to support, not just the map Tell me what data you have and what you want it to do. I’ll reply with an approach and a fixed-price or hourly estimate. 🤝 Let’s Work Together 📩 Send me a message to discuss your project.
