I will build a custom web app with react, python, maps and apis


About this gig
Do you need a custom web app, internal tool, dashboard, map-based platform or automation system?
I can help you build practical and clean web applications using React, Python, FastAPI, APIs and databases. My focus is on creating useful tools that solve real problems, not just simple static websites.
I have experience developing full stack projects such as ChillMap, a mobile/web app based on maps and geolocation, and GISTOMATIC, a GIS web application for analysing project constraints using official map layers, cadastral data and interactive results.
I can help with:
Custom web apps and MVPs
React frontend development
Python/FastAPI backend APIs
Dashboards and internal tools
Forms, filters and database integration
Map-based tools and geolocation features
Automation of repetitive technical processes
Before placing an order, please send me a message so we can define the scope, features, data, design and delivery time clearly.
Complex platforms, payment systems, advanced authentication, hosting costs or large-scale systems are not included unless agreed before ordering.

FAQ
Do I need to contact you before placing an order?
Yes, please contact me before placing an order. Every custom web app is different, so I need to understand your idea, required features, data, design preferences and deadline before confirming the right package.
What kind of web apps can you build?
I can build custom web apps, MVPs, dashboards, internal tools, forms, API-based platforms, map-based tools, automation systems and simple database-connected applications using React, Python, FastAPI and related technologies.
What is not included in the packages?
Complex platforms, payment systems, advanced authentication, hosting costs, large databases, full mobile apps, external paid APIs or very large GIS processing features are not included unless we agree on them before placing the order.
Can you work with maps or geolocation?
Yes. I have experience building map-based tools using interactive maps, geolocation, layers, filters and technical data visualization.
Will I receive the source code?
Yes, the source code is included if selected in the package. I can also explain the project structure so you can understand how it works.
Can you build a full mobile app?
I can work with mobile apps using React Native and Expo, but full mobile apps are not included in this Gig by default. Please contact me first so we can define the scope and price.
