I will build a custom web app with react, vue, or fastapi
Jose Monterola
About this gig
I build custom web applications from scratch no page builders, no CMS limitations, just clean code built exactly to spec.
I work across the full stack:
Frontend: React, Vue.js responsive, interactive interfaces including dashboards and data visualizations
Backend: FastAPI, Node.js APIs, business logic, integrations
Database: PostgreSQL schema design and data modeling
Integrations: REST APIs, third-party services, Google Sheets as a live data source, custom algorithms
Some things I've built: a full-stack scouting platform analyzing 4,000+ real players with a custom percentile-ranking algorithm and interactive dashboards, a rankings portal powered by a live Google Sheets backend, and custom-coded landing pages for clients who needed something a page builder couldn't deliver.
I'm based in El Salvador (GMT-6), comfortably covering US and Latin America business hours.
If you need something custom-built a dashboard, an internal tool, an API integration, or a web app with real logic behind it let's talk about your project.

6+ years of combined experience building and maintaining websites and web apps, and running day-to-day IT/SaaS operations for multiple client organizations at a MSP.
On the dev side, I specialize in WordPress and HubSpot CMS development (HubL, HubDB, custom modules), and go full-stack with React, Vue.js, Node.js, FastAPI, and PostgreSQL when a project needs custom functionality, APIs, databases, integrations.
On the IT/SaaS side, I administer 20+ business platforms, user and access management, licensing, device management (MDM), and account security (MFA, access reviews).

FAQ
Do you only build with React/Vue/FastAPI, or can you work with other stacks?
Those are my core stack, but I also work with Node.js and have experience with REST API integrations more broadly. Tell me the details of your project and I'll let you know if it's a good fit.
I don't have a traditional database — can you still build something for me?
Yes, I've built apps using Google Sheets as a live data source instead of a database, which works well for smaller projects or teams that want to manage data without a technical admin panel.
Can you build a dashboard or data visualization tool specifically?
Yes, that's one of my strongest areas. I've built dashboards with interactive charts and custom scoring/ranking algorithms.
What do you need from me to get started?
A clear description of what the app needs to do, any existing design or wireframes (if you have them), and access to any data sources or APIs the app needs to connect to.
