Experience
Eduscopio: A School Ranking Platform
https://eduscopio.it/From the back-end point of view, I used two DBMS and MySQL to read the website's structured information and MongoDB to write in real-time through WebSockets user statistics and usage logs. I used Hapi.js as a server framework with a REST API design. I integrated Twitter SDK to show the latest tweets from Fondazione Agnelli on the homepage, a simple CMS to create an internal blog section, and a PDF generator.
For the front end, I used a custom React single-page application. I developed two different versions, one optimized for mobile and the other for desktop. I also developed an animation system to create a helpful and friendly user journey. I integrated Google Maps API, geolocation, a WebSocket system to track user interactions, chart animations, dynamic list sorting, and a custom product tour system as a tutorial.
Pangea Professional SaaS
https://ecommerce.pangeacloud.it/Thanks to this SaaS platform, professionals could buy subscriptions to use Pangea Cloud software directly in their web browsers.
Ripit
QuARcore eCommerce Solution
The platform includes an institutional website, an AWS SasS platform, and a React Native mobile app.
I developed and deployed a large portion of the project and managed a team of four.
Welfare Informa Platform
The platform's goal was to build a dynamic catalog of measures to combat poverty based on a database that helps operators in all front offices easily understand and access the map of different services. I followed the entire flow of the platform by managing a team of four people, from the UX and UI analysis to the development of the back-end logic, front-end interfaces, and deployment on AWS systems.
Adhesion App
I am the co-founder and lead developer of this app. I oversaw the development of the REST API server and the mobile app in React Native.
Spazio alla Scuola
Conceived by the Agnelli Foundation with the BIM Group of the Politecnico di Milano and the University of Turin, the tool provides school managers and their collaborators' concrete support to check the school spaces' capacity and plan staggered flows of classes at the entrance and exit.
Claranominis
I worked both on the front- and back-end sides, combining AWS serverless with React SPA capabilities.
Introducely
Maptive – Version 5
https://www.maptive.com/I brought in new features for version 5 and managed the development process with three other lead and junior developers. I assigned them tasks on the Asana PM tool, reviewed their code, and participated in weekly meetings with the founders and the other lead developers.
Beautylish Launch Club
https://www.beautylish.com/launch-clubBeautylish
https://www.beautylish.com/Sublime Security
Excelsiorienta
https://excelsiorienta.unioncamere.it/The platform was developed entirely with Next.js. It takes advantage of almost all rendering technologies, from SSR for search pages via query parameters and news to SSG for static pages such as the about page, the cookies and privacy page, and two special sections rendered on the client side: one for the CMS admin side and one for the internal orientation game called OrientaGame. These two sections are two SPAs within the project in Next.
Novacoop
https://www.novacoop.it/1. A server-side rendering system based on an internal CMS engine built with MUI, React Router, Redux, and Redux-Saga.
2. Pages that are fully rendered and used as single-page applications (SPA) that compose the admin CMS panel.
3. End-to-end services to retrieve Coop's customers and physical shops' locations.
The project uses MongoDB as a DBMS, several endpoints and models for reading data, and some scripts that convert data from some CSV files into Mongo collections, as well as a complete CMS to build almost all front-end pages. It was deployed on AWS with Amplify Hosting and uses S3 buckets for assets, CloudFront as CDN, and Route53 for DNS and domain management.
BallerCam
https://ballercam.com/SaleAssistant AI
https://www.saleassistant.ai/On the front end, I built a React/Next.js interface with modular and responsive components to deliver a smooth user experience. On the back end, I managed REST APIs and AI-driven workflows powered by OpenAI and custom microservices, as well as caching layers and optimized databases for high performance.
I implemented Stripe to handle recurring payments and subscription management, along with Calendly integration for automated demo and meeting scheduling. Additionally, I developed an admin SPA to manage teams, users, and onboarding flows.
The project also included AI-driven marketing workflows for automated content generation, analytics tracking through Google Tag Manager, and CRM integrations.
GolfOne.ai – AI Operating System for Golf Courses
https://www.golfone.aiTech stack: Next.js + React Native (Expo) on the front end for web and mobile, with shared modular UI components. Back end on AWS with MongoDB Atlas for data, REST APIs, and multi-tenant isolation across golf clubs. Sentry for observability and proactive bug tracking.
Implemented PowerTranz as payment gateway for the LATAM market (Caribbean/Central America), handling subscriptions and per-round tee-time payments with full integration into the booking flow. Wrote comprehensive unit tests covering critical business logic (booking conflicts, pricing rules, player matchmaking).
Delivered the platform from concept to first live golf club, including admin SPA for course managers, public-facing booking site, and native mobile app for members.
