This is where I work for other companies, I'm trying to be as helpful as I can to provide their needs of IT consultancy. Mostly protocol developments, but also some infrastructure, tooling, backend or front-end development.

I try to give my best accross various subjects that I could have encountered through the years (blockchain, automated trading system, data processing, data pipeline, peer-to-peer systems, AI and automation, etc...).
While learning a lot in term of financial and trad-fi knowledge. I had prior experiences in ICO, their whitepapers, tokenomics, etc... but this in-depth experiences in RWA and launching/managing stablecoins.
Workign on bonds subject, with defi platforms, was really interesting.

Subject were on all fronts: from security, to launch, to tokenomcis, flows, developments, hiring, team endeavours and best practices sharing and including some inventions or broader web2 tradfi subjects. This time included working closely with AWS (KMS, EC2, S3 etc...) or Chainlink (price feeds, oracles , functions, secrets, etc...).
I also had the opportunity to build an automatic trader system, something that inject raw values (like individual trades on crypto or stocks) and form them into candles.

Those are then processed by ~40 indicators that are input of a set of strategies and robadvisor system (they understand the timeframe and adjust in accordance).

A trader robot would then handle both the entry point (getting your buy at the best price), and it's internal management logic (stop loss, take profit, risk management, etc...).

Some more sophisticated logics have been built (like iceberg orders, market making, arbitrage, MEV, passive income via DeFi, etc...). And a sentiment system interpreting the news and social media to add more info.

The early research and development that later would give Scintilla was done during that time, which was working with the Stellar Fondation, with Web3 projects and DAOs, and really learn about what is the problem really and how can we improve things.

It's still ongoing, and I'm happy to be learning so much right now and build so many cool things.

This is also the main vehicle for financing the building of the Scintilla ecosystem. Scintilla aims at bridging all those best parts together, building on top of the best project when able to provide to them the best infrastructure for their long term growth. I'm trying to learn the best from their limitations in Web3, and try to see how they would have wanted it in the first place. Keeping a MIT / OSS logic in building that, I'm in hope that at the right time for them, the right tool could support their needs, while in parallel, I can work to offer the Robinfolio Automated Family office tool, Nautilus Exchange in the means of Scintilla Clusters, and the base layer of Scintilla and initial agentic system.
