### TOM'S Presentation

***7 Unexpected Lessons from 2 Years of our SDK in Banks*** ***- from April 8, 2020 - FINOS Virtual "Meetup"***

 

 

GreenKey provides an open-source SDK to empower banks to extend our NLP engine with custom interpreters.  Over the last 2 years, we've learned much: we'll share the top 7 most surprising things our startup encountered, how we solved for them, and how you might avoid them altogether.

### FINOS Virtual "Meetups"

As part of our continued commitment to provide value to our Members and our greater Community, FINOS is expanding our use of virtual meetings and digital communication. While we know this can’t replace our in-person meetups (in New York, London, and Edinburgh), conferences (Open Source Strategy Forum - OSSF - in London and New York), and exclusive FINOS Member Meetings, we think it is a great way for our Community to share their achievements, ideas and even challenges related to open source in financial services.

**FINOS will continue to produce short, regular “meetups” via WebEx (usually on a bi-weekly basis), with guest speakers we often feature in our in-person meetups and at OSSF.**  April’s theme is “Overcoming barriers to open source collaboration in financial services - with practical examples.” [**Join us to see real examples of successful collaboration**](https://www.finos.org/hosted-events?utm_campaign=2020%20Content%20Marketing&utm_source=hs_email&utm_medium=email&_hsenc=p2ANqtz-9aPVRzN3VNYtj0rOe2gzjwCovX1Uihn-HhUiLwM7_zatLKRJRp-KZRWC4gmexnh2y2VcDA), hear a few top tips from active contributors, and learn about some innovative approaches to maintaining open source projects.
