About Me:
I'm a Frontend passionate developer, based in Rimini, Italy who
loves to code and create engaging and pleasant user experiences,
and especially loves frontend engineering and astronomy. Always
ready for new challenges I have been
programming since I was 12 when my father handed me a book about
HTML basics, and I have loved doing it since then! When I'm not
coding I'm probably working out or practicing Kung Fu (pak hok
pai). Currently working at
Roomex
as a Senior Frontend Engineer!

Education and Courses
Bachelor's Degree in Computer Engineering - Universitas Mercatorum (2018 - 2022)
Throughout my academic journey at Universitas Mercatorum, accredited by
the Italian Ministry of University and Research (MUR), I pursued a
Bachelor's degree in Computer Engineering, which provided me with a
strong foundation in programming, algorithms, and software development
principles. I completed the final years while already working
full-time as a developer, which is exactly what let me put the theory
straight to work in my career as a Frontend Engineer. A Diploma
Supplement in English is available on request.
Courses I attended
In addition to my formal education, I have also actively pursued
further learning opportunities through courses. These courses have
allowed me to learn new things, get a deep knowledge over different
topics and improved my skills. Here is a selection of the courses I
have completed:
- Angular the complete guide (2023) - Maximilian SchwarzmΓΌller
- Angular testing masterclass (16) - Angular University
- Production-Grade Angular - Lukas Ruebbelke (Frontend Masters)
- Angular Fundamentals - Ultimatecourses.com

Work History
Welcome to my Work History section! I am a passionate Frontend
Engineer with over 8 years of hands-on coding experience, specializing
in TypeScript, reactive state management and single-page application
architecture, and I have built production web applications for
enterprise clients including Mastercard, Maserati and Intesa Sanpaolo.
Holding a Bachelor's degree in Computer Engineering, I have honed my
skills and expertise to create captivating and efficient web
applications. My journey as a
developer has been driven by a relentless thirst for knowledge and a
strong desire to push the boundaries of what's possible in web
development. Currently, I am proud to be a part of the talented team
at
Roomex, where I continue to grow, contribute, and innovate in the
ever-evolving world of technology.
Roomex (Corpay)
02/24 - Ongoing
Senior Frontend Engineer
- Core engineer on the booking platform, an Nx monorepo of 15 applications and 210 shared libraries serving two white-labelled brands. I have progressed from feature delivery into technical design ownership, authoring the technical design documents and milestone plans that other engineers build against.
- Led Child Occupancy, the platform's largest search change to date, end-to-end: from authoring the technical design through delivery across search, deep-link URL contract, results filtering, hotel detail, room selection, guest forms, checkout, confirmation, amendments and manage-booking. The typed search-mode model and reactive child-age form architecture it introduced are now reused across the booking funnel.
- Enabled Corpay Lodging to launch as a second brand without forking the codebase, by architecting a semantic SCSS design-token system that replaced hardcoded styling across the shared component library and every consuming application (165 files: themes, typography, tokens, animations, directives, validators).
- Shipped Travel Time on Map, letting travellers judge hotel proximity at a glance via live driving routes, duration and distance. I integrated the Google Maps Routes API as a reusable shared-library service, released as 12 feature-flagged milestones with async loading states, error handling and long-route edge cases.
- Reworked the hotel search, resulting in a 10%+ increase in conversions, and eliminated a class of reliability defects caused by stale, out-of-order API responses that intermittently returned incorrect hotels.
- I have kicked off the contract between Backend and Frontend for an internal configuration management tool using OpenAPI specs, creating a scalable API easy to use. This made possible a smoother Fronted-Backend decoupling.
- Authored 81 unit test suites and hardened accessibility (ARIA state bound to signals, live-region announcements) and localisation across the new search and map interfaces.
- Built internal developer tooling adopted by the wider engineering team: a QA Recorder browser extension that turns manual QA sessions into runnable Playwright specifications, and a set of AI agent skills orchestrating spec-driven development workflows.

Personal projects
I build a lot of things on my own time. Most of them stay experiments, but three of them turned into real products with real users, and these are the ones I'm proud of:
η©γθͺγΌγ Β· Tsundoku Zero
Japanese grammar practice, one lesson at a time β React
- Live and open to anyone. I built it for a gap I hit in my own studying: the Cure Dolly grammar lessons recommended by the 30 Day Japanese plan are excellent, but almost no exercises come with them, and what you stop practising you forget.
- I write every exercise myself, lesson by lesson, as I work through the course.
- Scheduling is spaced repetition: an exercise you get right comes back after a longer and longer gap, one you get wrong comes back sooner. Clear the pile for the day and the next lesson unlocks.
- The name is the whole idea. η©γθͺ is the habit of letting bought books pile up unread; the queue in the app is that pile, and the point is to get it to zero.
Omni
Consumer and B2B mobile app for San Marino β Flutter, Dart
- Live on the App Store and Google Play with 560+ downloads and 99% retention.
- A single app covering local news and events, a live business directory, community Q&A, a five-board marketplace (items, cars, property, jobs, public tenders), bookings and fuel prices, across all nine municipalities.
- I built a natural-language AI assistant that understands local places, services and opening hours, ranks results by relevance, and routes the user straight to the listing, map or booking rather than only answering.
- I delivered the business-facing side too: profiles, job postings, team members with scoped permissions, statistics, and multiposting to Instagram, Facebook and Google Business.
Autocompila
AI agent for legacy business software β React, Electron,
TypeScript
- Currently in private beta.
- It reads inbound email, PDFs and free text, extracts structured data, and fills existing ERP software through visual automation, with no API integration or migration required. Every record is confirmed by a person before it is written.
- Built as an Electron desktop application, which is what allows it to drive software already installed on the customer's machine: the architecture is local-first, data never leaves their environment, and every action is recorded in an audit trail. Field mapping is configured visually by the user rather than in code.
