I build data- and API-heavy platforms on Laravel + React — and own them end-to-end. My focus is the parts most developers bolt on as an afterthought: interactive maps (Mapbox / Leaflet / Google Maps) and Meta / Google marketing-API integrations. 15 years, 50+ projects delivered, 100% Job Success.
I work best on systems built to last and grow — but I'm just as happy taking a single, well-scoped task to start.
⚙️ FULL-STACK WEB PRODUCTS
Laravel APIs paired with React frontends, built to last — not just to ship. From SaaS platforms and admin dashboards to a multi-brand CMS engine powering 15+ automotive dealer websites (Volvo, Mercedes-Benz, Alfa Romeo, Jaguar, Land Rover).
🗺 Interactive Maps — Mapbox / Leaflet / Google Maps API
◾ Custom maps: styled tiles, markers, plotting live data
◾ Map tools: drawing & editing shapes, measurements and calculations on the map
◾ Example: a solar-PV design tool with live roof mapping
🛠️ Meta Graph / Marketing API
◾ Lead capture: real-time leads delivered straight to CRM, email, or messenger
◾ Ad tooling: custom reporting logic, automated insights, campaign automation
◾ Publishing & analytics: posting to Instagram/Facebook (feed, stories), post & profile insights
🗃️ Google API
◾ Custom Looker Studio connectors
◾ Google Merchant Center feeds (recent project: 30k+ SKUs synced)
◾ Google Ads automation tools
💳 Payments
◾ Standard and custom Stripe / PayPal / Afterpay integrations
However you want to start — a full build, a senior pair of hands on an existing codebase, or one focused task (a map feature, a Meta/Google API integration, a tracking or feed setup) — I'm easy to work with and quick to get going.
Send a short note about your project, even a rough idea, and I'll tell you honestly how I'd approach it. 🤝
Thank you,

How to Hire Top Google Maps API Developers
How to hire Google Maps API developers
Imagine how hard it would be to create a maps app that was as thorough, expansive, and accurate as Google Maps. With the Google Maps API it’s possible to leverage Google’s existing maps technology in your own app.
So how do you hire Google Maps API developers? What follows are some tips for finding top Google Maps API developers on Upwork.
How to shortlist Google Maps API professionals
As you’re browsing available Google Maps API consultants, it can be helpful to develop a shortlist of the contractors you may want to interview. You can screen profiles on criteria such as:
Technology fit. You want a Google Maps API developer who understands the technologies behind your app.
Project experience. Screen candidate profiles for specific skills and experience (e.g., creating heat maps with the Google Maps API).
Feedback. Check reviews from past clients for glowing testimonials or red flags that can tell you what it’s like to work with a particular Google Maps API developer.
How to write an effective Google Maps API job post
With a clear picture of your ideal Google Maps API developer in mind, it’s time to write that job post. Although you don’t need a full job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if they’re the right fit for the project.
An effective Google Maps API job post should include:
Scope of work: From adding a map to your website to visualizing data with a heat map, list all the deliverables you’ll need.
Project length: Your job post should indicate whether this is a smaller or larger project.
Background: If you prefer experience with certain technologies or developer tools, mention this here.
Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.
The Google Maps API provides a set of APIs and SDKs (software development kits) that can be used in your own app. From simple embeddable map images for your website to 360° panoramas through Street View, a Google Maps API developer can help you use Google Maps in your apps.
