Day 2 of apidays NYC was all about FINOS for me. I spent the entire day in Room Emery (except for a few quick bathroom breaks), immersed in a full lineup of talks and demos centered on APIs, open source, and finance tech.

We kicked off with Olivier Poupeney, FINOS Field CTO, setting the tone for the day. He promised a packed schedule covering cloud, AI, fake trading apps, communication buses, and more — and he delivered. The speaker lineup was stellar, featuring Nicholas Kolba, Daniel Paes, Tom Healey, Daniel Schwartz, Diego Mastroianni, Xiao-Yang Liu (Yanglet), Leigh Capili, Mia Gougisha, Rob Moffat, Luca Borella, and many more.

We started by exploring the real legend — Legend — presented by Daniel Paes. Alongside it, he introduced the FINOS Common Domain Model (CDM) through an IFRS17 insurance regulation compliance use case. But we needed more CDM — and Tom Healey delivered. He expanded on how CDM intersects with Web3, DLT, and blockchain. (Who had that on their bingo card?)

Daniel Schwartz followed with practical insights on integrating CDM into your API calls — a perfect fit for apidays.

Then came the best session of the day — mine! I presented TraderX, the open source, cloud-native, but entirely fake trading app. I dove into the why’s, how’s, whatnots, and explored its extensibility, flexibility, and — of course — APIs. I had to skip some great talks on FDC3, AI Governance, and Cloud Control to answer all the amazing questions folks had about TraderX at the FINOS booth.

The day continued with Diego Mastroianni’s session on transforming with GenAI. He opened with a powerful question: “Is there anyone here who hasn’t used GenAI yet?” He teased an upcoming FINOS GenAI Orchestration platform — name TBD at a future conference.

My final session of the day was Xiao-Yang Liu’s incredibly technical and detailed walkthrough of AI in finance — from A2A to MCP, from FinGPT to “relearning.” I was so impressed I invited him to share more at an upcoming Zenith call!
