We have been very busy

Well, here we are in 2019, and I am sorry to see that this ‘journal’ hasn’t worked out as planned. But we do have so much to show for the last few years and I wanted to get that on the record here!

  • We have developed our ‘Hoist’ framework into a highly productive platform for building desktop and mobile HTML5 applications. With a solid Grails/Java back-end, and a modern ReactJs/MobX front-end, Hoist brings together all of the technologies needed to build polished, scalable web-apps. Over the last two years, we have completed a major restructuring of Hoist from the Sencha framework to React, and I am happy to report that Hoist toolkit is better than ever. Please see and give it a try!
  • We have continued to expand our client-base in the hedge-fund world, building real-time trading systems, and dashboards for new clients, and continuing to support, enhance, and upgrade mission critical apps for existing clients. Polish, performance, and maintainability of the UI layer remains our focus.
  • Our team has grown in New York and beyond. We have moved into new offices in Larchmont, NY, just 35 minutes north of midtown via train. We are offering great benefits, and are continuing to grow our team with talented junior and senior engineers.

If you love code and user interfaces, are interested in building highly polished products with new technology, and want to work with a great team, please reach out to us at!

You’ve got to start somewhere…

By | Meta

We’ve started up 2015 with a bang, as several big projects hit production with new releases and a number of exciting new apps now swing into active development. We’re making good progress on Hoist, our Grails plugin for rapid app development, and we’re building out our infrastructure and our ability to scale and grow with our clients. We’re energized and charging into the future.

So it’s been a bit crazed, to be honest, but it also seemed like a good time to revamp our site and pull together some content of our own. We hope this journal can record our experiences with enterprise web development and technology in general, and that it might be of interest to our visitors. Or, at the very least, that it might be interesting to us. And help us remember how we fixed that thing that broke.

For now, though, we’ll leave it at this. You’ve got to start somewhere.
