# Node.js development

## Why we choose Node.js

Node.js is a server-side JavaScript runtime built on Chrome's V8 engine, designed for I/O-intensive applications. At Tupaca we choose it when the project needs high concurrency, fast APIs and a single language across the whole stack to speed up development.

We mainly use it for web application backends, REST and GraphQL APIs, and real-time services, where the priority is performance, horizontal scalability and simple integration with the npm ecosystem.

## Benefits of building with Node.js

- **High I/O performance**: Its asynchronous event model handles thousands of simultaneous connections without blocking the server.
- **Same language end-to-end**: Using JavaScript on both the frontend and backend means a leaner team and faster delivery.
- **npm ecosystem**: The world's largest package registry lets us add functionality without reinventing the wheel.
- **Horizontal scalability**: An architecture built to grow with microservices and load balancing.

## Our success stories with Node.js

- [The Walt Disney Company](https://www.tupaca.com/en/success-stories/disney): Since 2017, a Tupaca team has been building the advertising billing system for The Walt Disney Company's digital and streaming businesses in Latin America.
- [Bayer](https://www.tupaca.com/en/success-stories/bayer): From 2018 to 2022, we embedded a team of up to five senior backend developers in Bayer's engineering organization, working full-time on global-scale projects.
- [La Nación](https://www.tupaca.com/en/success-stories/la-nacion): We added a senior Python developer to La Nación's data team and built a dashboard that puts the news site's key metrics on the office videowalls in real time.
- [maximstore](https://www.tupaca.com/en/success-stories/maximstore): We built the custom e-commerce platform for maximstore, one of the region's leading Apple resellers, serving Argentina and Uruguay — and a PunchOut-enabled B2B portal that lets Techint's team buy through its own procurement system.
- [Gamer Factory](https://www.tupaca.com/en/success-stories/gamer-factory): We built a custom e-commerce platform for a gaming hardware retailer. The toughest piece: a PC builder that lets shoppers spec a rig part by part while checking compatibility at every step.
- [Fertygen](https://www.tupaca.com/en/success-stories/fertygen): We built Fertygen's management system from scratch: software that runs the fertility clinic end to end and keeps each patient's full medical history in one place, developed faster with AI tools.
- [IDHS](https://www.tupaca.com/en/success-stories/idhs): We built IDHS's course and training platform from scratch for the education institute of the Municipal Physicians Association of Buenos Aires: course catalog, enrollment, payments and online teaching, all in one place.
- [Ephere](https://www.tupaca.com/en/success-stories/ephere): We built Ephere Football from scratch: a Web3 soccer manager where players, stadiums and currency were tokens, with AI-powered match simulation — later merged with MetaSoccer into a single game.
- [Eclipse Group](https://www.tupaca.com/en/success-stories/eclipse-group): We built Eclipse Group's airside operations platform and mobile app for wildlife hazard management, aligned with FAA standards. It was deployed at airports including Miami and Dallas and named one of the 10 most innovative ideas at eMerge Americas.
- [Wama](https://www.tupaca.com/en/success-stories/wama): We built a production management system for Wama, a Mexican sportswear uniform manufacturer, that tracks every order in real time. With AI across the whole process, we delivered it 10x faster than we could have without it.
