My ideal job

I'm a Senior software developer and hands-on tech lead; my ideal job is a project to have an impact on. I love to work side by side with Product and UX to help shaping the future of tech products.

What I’ve worked on

My biggest achievement has been working with IAC on a project called Werkspot. I’ve been asked to work between London and Amsterdam on a very challenging project: a gradual rebuild of the website (avoiding a big-bang release), keeping the website running, keeping experimenting on new features, with a team of 8 people that never worked together before. I’ve managed to make it happen, without losing revenues and by improving the website performances. I’ve worked on hiring the team of developers. I’ve then worked with an amazing product/UX team to the new design and user experience of the website. Last but not least, we have successfully migrated from an old legacy monolith to scenario-driven APIs with a responsive website as main API client.

Side Project: forgetbusy

I’ve been running my own side project in order to keep experiment with new technologies. The aim of forgetbusy is to bridge the gap between marketers and technology. With forgetbusy we're building modern and simple apps that save time.

Current role
Senior Software Engineer at LocalHeroes / British Gas
Oct 2020 - present
LocalHeroes / British Gas

Local Heroes is an innovative new network connecting customers with local tradesmen for a variety of jobs including plumbing, heating and drainage services and electricians. The fast growing start up backed by British Gas.

Technologies used for this project
Frontend: Javascript (ES6), Typescript, React + Redux, React Native + Redux, Next.js, CSS3 (SASS), UI component library, Material UI, Webpack, GraphQL, Jest, ESLint, JWT + Auth0.
Backend: Node.js, Express, AWS, microservices architecture (both frontend and backend) based on Docker, deployed with Terraform and Codeship.

I worked on many of the micro-services and micro-frontends that power the company products. I was responsible for the full lifecycle of many applications, from shaping to development, to automation testing, to deployment.

The backend microservices have been build in Typescript on Express and they expose GraphQL endpoints authenticated by JWT tokens.

The frontends have been built in Javascript on Next.js using Material UI or an in-house built UI components library. The components have been built in React with Redux and Hooks; CSS has been build in SASS with CSS modules following a BEM-like convention. Code style has been kept consistent in between teams by applying Airbnb ESLint rules, including CSS linting. I was also in charge of the React Native iOS app/wrapper which also uses Redux. All apps have been built mobile-first and responsive.

Multiple testing strategies have been put in place, from Unit to Integration tests using Jest, including end-to-end. The infrastructure has been managed by Terraform and the applications have been packaged into Docker containers using Codeship. Each application lives in its own git repository with it is own lifecycle. The services make extensive use of multiple AWS services, from container related (ECR/ECS), to databases (like RDS and Elasticsearch), to storage (S3) to Lambda and step functions.

My project
Co-founder at forgetbusy

The frontends run in Lambda/serverless (Vercel).

Backend: microservice infrastructure based on GraphQL (Apollo on Node.js) packaged in Lambdas on AWS. Datastore: MySQL. Background jobs run in Lambda, Docker containers (AWS Fargate), Step functions.

Infrastructure: I take care of architect and deploy our cloud-based infrastructure, hosted on AWS. The infrastructure is Terraform-ed and it is built and deployed via Github Actions and Github packages. We also use CloudFlare as CDN/DDoS mitigation.

Data get pulled from APIs and an FTP server, processed, stored and returned via RESTful APIs to be consumed by a fully-responsive React frontend. React Server rendering has been used to produce the PDF reports.

We aggregate data from different providers and we merge the information with what has been submitted from artists and manager from all around the world. We process over 23 million datapoints every week. It all gets organised and transformed into valuable information.

The system intelligently matches artists and venues and automatically suggests the best gigs for each artist. We scan the artist's calendars to help promoters organising events. We also scan similar artist's calendars in order to provide helpful suggestions.

It all happens in few milliseconds, using a dataset containing over several million of pieces of information.
