Sell Gods Unchained cards instantly for GODS.

As an active participant in Gods Unchained marketplaces I saw the need for an "instant sell" product.

GameFi is really interesting and probably the best reason for being bullish on crypto

My digital art gallery.

Needed an excuse to build an app with the web4th framework. I like to draw so I decided to build my own art gallery.

I'm happy with the article and the app. It's still v0 but the built-in support of a web4th app is buttery.

Meeting for coffee? Sign a contract.

Was brainstorming silly ideas to try this new Clojure "framework". Thought about coffee meetings.

Got excited about 1/ removing template-creating lawyers and 2/ removing frontend-backend separations.

Invest daily in top Gods Unchained cards automatically.

As a Gods Unchained player and believer, I wanted a way to passively invest in GU cards.

I'm considering making it open source so that anyone could run their own bot.

Use your bank account as a crypto wallet and buy into DeFi.

Discovered Monerium and had to dig deeper. The best way to go from EUR to crypto.

This was a POC but I'm glad I could show the potential of Monerium.

Smart contract security audits.

Decided to get better at understanding Solidity and went into competitive security audits.

I definitely got better at Solidity, but didn't manage to reach a profitable level. Auditing is fun but building is better.

MEV (Maximal Extractable Value) on EVM chains.

What a weird world. But a world where there's no room for approximation. You have to be the absolute best to get a chance.

After fighting in the mempool for a few months I decided to pause that activity because of low volume (was doing mostly NFT arbitrage and liquidations).

Coliving powered by crypto.

Coliving is the future. And it would have been a perfect use case for crypto in the real world.

Hopefully a project like this happens in the future. Coliving as a public good ♥

web4ᵗʰ: the temporal web.

This was one of the main topic for my sabbatical. The idea was to add time as a new dimension on the web.

I'm still convinced that this is a superior format. It's up to me to convince more people now.

Bribes for Curve voters.

Welcome to deep DeFi. My friend working at mStable had the idea to build an on-chain bribing platform for Curve voters.

Transparent bribing is an interesting concept. But I now feel DeFi went a bit too far...

Visualize your Argent guardians.

Argent is one of the best way to self-custody crypto with their guardians. But I wanted a way to see guardians as a graph and to assess its robustness.

Graph theory is not so straightforward.

Enzyme adapter for PoolTogether.

I've always been a fan of PoolTogether (no-loss lottery) and the integration was missing on Enzyme. I put together a proposal to build it.

Getting to know an intricate set of smart contracts was a good challenge.

On-chain crypto hedge fund.

I had a group on Messenger where I gave crypto tips. I decided to turn it into a proper fund thanks to the Enzyme platform.

I accepted 35 depositors into the fund. Now trying to be ready for the bull market of 2023 ☺

Minimalism: I've got 99 items.

Towards the end of the first lockdown I started making a list of all the items I owned. Minimalism FTW.

The list is definitely not up to date as I'm using objet.cc now.

Improving CryptoTwittos.

Still locked down and bored. Wanted to re-launch CryptoTwittos (see below) with a better architecture (NFT support).

My life became literally 100% crypto during the first lockdown. I got overwhelmed and didn't release it.

MEV: buy on TokenSets, sell on 1inch.

This was covid time, working with an ex-colleague. I came up with the design: flashloans on Aave, auctions on TokenSets, trade on 1inch.

Flashloans are fascinating. This concept doesn't exist in the legacy world, only in Crypto.

Conference talk: streaming parens.

Gave a talk in London at a Clojure conference. Built a small app for the occasion to showcase the power of serverless architecture.

Was the first time using GitHub actions. I was impressed.

Crypto wallet for companies.

Started working with eFounders on this project. Then onboarded a cofounder. We did YC in the summer of 2019. We raised millions.

The company is still going. I left in 2021 as this was not working with my cofounder anymore.

Social network for movie recommendations.

Got in touch with two business guys who needed a tech person to build this app. Idea made sense.

Building a Messenger bot was interesting. But I would not work again with people without technical knowledge.

Own Twitter accounts, on the Ethereum blockchain.

I was going all-in in crypto and had just finished an Ethereum course. Wanted to get my hands dirty and build something that would make sense on-chain.

Users would collect and steal (virtual) Twitter accounts from each other. Fun time.

Mining rig to provide hash power.

I got the idea of getting into crypto mining. We built a mining rig with a friend who kept it in his attic. Converting electricity into coins.

Hardware is such a mess. Very hard to debug. Thank god I'm mostly in software.

Slack game to get better at knowing your coworkers.

This was a warm summer in Corsica and we had just read a book about "Chatbots". With my gf we built that Slack app following those bot principles.

First serious attempt at conversational interfaces. Something felt right about it.

Game: how many mountain ranges in the Alps can you recognize in 42 seconds?

This was a fun side project when launching the summer version of Booctin (see below). The goal was to build something that could drive organic traffic to us.

One of my favorite codebase. So clean ♥

Find the perfect spot to hang out with your friends according to your positions.

Inspired by Bornycentre (see below), I built this more useful tool with my gf. Finding a good spot to meet in the middle is never easy.

Crazy that Foursquare was such a big thing.

Ski instructor booking platform.

A childhood (mountains) friend had the idea to try and modernize the ski instructor booking business. We quit our jobs and started Booctin.

We managed to get bookings but only by paying Google Adwords. We failed at the SEO game and had to close the company.

Learn to type fast with Type Letter.

This game was only built for me to try and use core.async. I needed an excuse to play with timeouts.

Old Clojure code always works well. Go play with it and tell me your score.

Marketplace to exchange Eurostar tickets.

Working with a friend at LifeWorks. We wanted to create a way for people like us to buy or sell Eurostar tickets which could be very expensive.

We never released it.

Find the place that represents the (iso)barycentre of the cities where you lived at least 9 months.

A very random idea. I don't remember why I built it but I still like it. Discovered Cycle.js at a conference in Bratislava and wanted to try it.

Trying to get that viral loop by letting people easily share their Bornycentre on Twitter.

Coding interview for JavaScript developers.

I was trying to hire JavaScript developers for the company I was working for. I created this small test to help me assess them.

Still ugly JavaScript, but that tail-recursive one-liner for question 8 is my favorite.

Game: find the 8 hiding between 9s.

A friend built this mini game in JavaScript. Another friend re-wrote it in React. It was time for me to prove that Clojure and Reagent were better options.

This was the beginning of a long love story with Clojure on the frontend.

Showing parking spaces on a map.

Another coding interview. Decided to use all the cool tech of that time. The goal was to display and interact with parking spaces on a map.

Coding interviews can be annoying but they also are great to make you build something.

Calendar app.

Applied to join The Facebook in early 2015. The first challenge was to build some kind of calendar app in JavaScript.

Facebook was really cool at the time. My carreer path would have been different. Glad it didn't happen.

Relaunching Tradixo. Kind of.

With Tradixo shutting down I still had all the translations people contributed on the platform. I built an interface to search through all of them.

It was my second React project. I knew this was the future. Unfortunately I had just accepted a Angular job ☹

Photos of London BBQs on a map.

Just wanted to try out things. Using Instagram's data and Google Maps.

Data was more open at the time.

René Coty tee-shirts.

Working with a friend at Dailymotion. Couldn't think of a better idea than selling tee-shirts with René Coty on them. Merci à toi, René.

René Coty is a French private joke made famous in the movie "OSS 117". The goal was to go viral. It did not happen.

Remote control for Dailymotion playlists.

Working with that same friend at Dailymotion. Wanted to use React.js and peer.js for a company hackathon. We built a webapp that could control a playlist page.

10 years later the fundamental idea of React is still the same. Probably time for a new paradigm.

Gamified social translation platform.

Was doing my Erasmus in Madrid. Struggled to get Spanish translations I could really trust. Decided to build a product where users could help each others with translation of short sentences.

Translation services have been getting radically better in 2023 but nothing competes with asking a native "how do we say __?". Mostly for bad words indeed.
