I build production web GIS platforms, real-time tracking systems, and spatial data pipelines, with 8+ years of experience delivering for logistics, real estate, agriculture, and government clients.
Because I cover both the spatial backend and the full-stack frontend, you don't need to coordinate three contractors — I take projects end-to-end, from PostGIS schema design through Mapbox GL JS frontends to AWS deployment.
Web GIS & Mapping
Mapbox GL JS, MapLibre GL, deck.gl, Leaflet, OpenLayers, Cesium, ArcGIS JS SDK, Google Maps API. Vector tiles (MVT), tile servers (TileServer GL, Martin, pg_tileserv), custom basemaps, 3D terrain, and WebGL rendering of millions of features.
Spatial Backend & Data
PostGIS, pgRouting, Oracle Spatial, ArcSDE, GeoServer, ArcGIS Enterprise. ETL with GDAL/OGR, GeoPandas, Shapely, Turf.js, and FME. Routing, isochrones, geocoding/reverse geocoding, spatial joins, and raster analysis. GeoParquet, DuckDB Spatial, Snowflake, Databricks.
Full-Stack Development
Frontend: React, Next.js, Angular, TypeScript, Tailwind, Material UI
Backend: Node.js (NestJS, Express), Python (FastAPI, Django, Flask), Laravel, .NET
Mobile: React Native, Flutter — with offline maps and GPS tracking
Databases: PostgreSQL, MySQL, MongoDB, Redis, SQLite, DuckDB
DevOps & Cloud
Docker, Kubernetes, Terraform, CI/CD pipelines, AWS, Azure, Google Cloud.
What I typically build
- Web GIS dashboards and field-data viewers
- Real-time GPS tracking, fleet, and telematics platforms
- Routing and last-mile delivery applications
- Property and real estate mapping portals
- Agriculture and environmental monitoring tools
- Geospatial APIs and tile-serving infrastructure
- Migrations from Esri/ArcGIS to open-source stacks (and the reverse)
I use Claude Code for coding.
I run a small GIS agency, Mapzx, and I'm happy to jump on a Zoom call to scope your project.

I'm a Senior React Native & iOS Engineer with 6+ years building production
mobile apps that ship — not prototypes. I've led development on a
government-scale GIS platform used by 1,500+ field officers to digitize
4M+ properties, architected a real-time WebRTC + Socket IO communication
platform for a multi-branch enterprise, and shipped 10+ apps to the App
Store and Play Store.
What I bring to your project:
- React Native + TypeScript — clean, scalable, well-tested code (Redux
Toolkit, React Query, Clean/MVVM architecture)
- Native iOS (Swift) when you need platform-specific performance or
features React Native can't reach
- Maps & GIS — Mapbox GL, Google Maps, MapLibre, geo-fencing, offline
map tiles (MBTiles/KMZ), anti-spoofing location tracking
- Real-time systems — WebRTC audio/video calling, Socket IO messaging,
AES-256 encrypted data flows
- Full mobile release lifecycle — Fastlane CI/CD, App Store/Play Store
submissions, code signing, production releases (10+ shipped apps)
- Backend when needed — Node, Express, Firebase, REST APIs, MongoDB
Recent work includes a government property-tax survey app (offline-first,
geo-fenced, deployed across 25+ municipal zones), a multi-tenant enterprise
communication platform (WebRTC and Socket IO), and an identity-verification
app with CNIC scanning and biometric authentication.
I've led engineering teams of 5+, run sprint planning and code reviews,
and I'm comfortable owning a feature end-to-end — from architecture
decisions to App Store approval.
Available for both contract and long-term engagements. I respond fast,
communicate clearly, and I don't disappear mid-sprint.
