Experience

LastMX

https://lastmx.com

We created LastMX with Thomas Recouvreux to allow the creation of unique aliases that redirect to the user's personal email address. The real address is never disclosed and sending/receiving processes are supported.

Location Diary

Location Diary was created for the Blockstack App Mining contest. It allows users to record their location history in a type of decentralized storage backed by blockchain.

Aristide Collection

I worked on improving the Aristide eCommerce website, with an updated design by Bonjour Paris. This included CSS animations and some innovative navigation elements, all built on top of the existing technology stack.

My Mobile Site

In 2008, Nokia developed a mobile web server running on Symbian smartphones, exposing some of the phone's features to the web. I wrote a Facebook application enabling interaction with this software: viewing phone location, sending messages to the phone, displaying pictures on a phone, and more.

Cheerswipe

Cheerswipe was created for the Makers Festival API Edition. It uses Product Hunt's GraphQL API to display public maker goals in a card-like UI and allows cheering them by swiping! It achieved the runner-up spot in the mobile apps category.

Buda Gallery

I created this app as I couldn't find an easy way to share my travel pictures with friends and family. Buda Gallery is extremely simple: visit the site, upload your pictures and you immediately get a link to share it. It uses serverless technology on AWS.

Fotokorner

Fotokorner is a SaaS allowing photographers to create client galleries and portfolios. The site uses a 100% Serverless stack: pictures are stored on AWS S3 blob storage, metadata on AWS DynamoDB, and the front end is a Next.js application deployed on Vercel. Image delivery, including thumbnails, is handled by CloudFront with Lambda@Edge.
