Hi, I'm Lotfi 👋
Building clean, scalable frontends with React and TypeScript— plus a touch of UI/UX sense.
About
After completing my Master’s in Computer Science with a focus on AI, I dove headfirst into frontend development. I’ve built and scaled projects for companies, shipped mobile apps, and launched platforms like Gassigo. I love turning concepts into real products, whether for work or on my own. Right now, I’m growing as a frontend engineer while also building projects like Gassigo — a platform that lets me experiment with product, design, and shipping ideas end to end.

I've worked on a variety of projects, from simple websites to complex web applications. Here are a few of my favorites.
Gassi Go
Gassigo is a dog-sitting app built for the Swiss market. It helps owners find and book trusted sitters through an interactive map, with clear roles for both sides. The app includes real-time chat using WebSockets, booking that syncs directly with Google Calendar, and secure login with Google OAuth. The frontend is built with React and the backend with NestJS, making it fast, reliable, and easy to scale.
El Hillal
El Hillal is a mobile app for browsing and ordering school supplies. It works offline-first, has smooth navigation, and lets users sign in to track both past and active orders. The goal was to make shopping for school materials simple and reliable, with a clear and easy-to-use experience.
CSV Visualizer
This is a lightweight web app for exploring and analyzing CSV files directly in the browser. It lets you visualize data instantly, filter and adjust columns, edit rows, and turn raw CSVs into clear insights — all quickly and securely without needing extra tools.
DevKit
DevKit is a lightweight, browser-based toolkit that brings everyday developer utilities together in one place. It includes tools like a JWT decoder, JSON formatter, regex tester, REST client, and more — all with a simple interface, built using React, Redux, and TypeScript
DeepCulture
Professional sample packs for Afro and Deep Melodic House producers, crafted to blend technical precision with creativity. The packs deliver ready-to-use sounds for modern electronic music, while also offering custom production services for artists and DJs who want unique, high-quality tracks.
Zambo
A bold, stylish landing page built for a tattoo shop. It uses smooth animations and strong typography to capture attention right away, with a dark modern vibe that matches the culture. The design is clean and responsive, so it looks great on any device. It’s made to showcase the shop’s personality, give visitors a strong first impression, and make it easy to get in touch or book.
