Main contributions:

• Lead the GraphQL API design.
• Lead the authentication layer using Auth0.
• Built the components library for our design system.
• Built various PoC to demonstrate different integration capabilities. - I was one of the few engineers to run demos to our existing and potential clients, including top tier banks.
• Introduced and promoted good React testing practices.

At the time TES was one of the largest professional network in the world with 8m+ teachers. The stack was based on 150+ node microservices and React on the frontend. Projects I've worked on included:

• Payment gateway: significant refactoring, allowing a reduction in bugs producing duplicated/missing transaction and lost revenue in the busiest part of the website, the resources marketplace (~500k views per day)
• Resources creator tool: introduced a secure and simple markdown editor migrating the existing 3m resources pages.
• Mobile apps: among other things I introduced GraphQL allowing a significant optimisation of the network usage and caching.
  I've also hosted internal knowledge sharing sessions about React Native, serverless and GraphQL.

As a Lead Developer I hired and managed another developer remotely and managed the relationship with an external web agency.
During my time working with TechHub we launched 5 international locations so it was important to build a platform that could scale, integrate with different payment gateways and deal with i18n.

I was hired to help them build the internal CRM and website.

It was a small agency that I helped for a few months with both frontend development and a bit of dev-ops, at the time mainly managing some nginx servers to deploy Wordpress websites and setting up DNS records.

I was the first to introduce responsive design concepts and I built the frontend for a couple of products using bootstrap css framework which, at that time, was quite innovative.

As a freelancer I was tasked to build the frontend for their e-commerce website and make it mobile friendly.

It was like Instagram meet Tripadvisor, a mobile app where you could search food visually and fine search for a specific dish.
With a friend we launched in Ticino, the Italian speaking canton of Switzerland and we had 250+ restaurant on the platform but eventually covid-19 happened and the hospitality business was greatly affected we decided to retire the project.

A mobile app built with React Native and a GraphQL node.js backend.
The app allowed users to receive restaurant discounts and optionally donate to charity.
The product didn't work out but it was a great experience and we manage to donate more than 5'000 CHF to charities.
