Background

## Where I've been

I've run GreenFlux since 2016, starting with no-code and low-code apps for small businesses, universities and the State of Florida. That work led to leading developer relations at Appsmith and developer experience at Handsontable. Here's the track record behind the [developer relations](https://www.greenflux.us/services/developer-relations) and [custom software](https://www.greenflux.us/services/custom-software) services.

## Head of Developer Experience @ [Handsontable](https://handsontable.com)

As Head of Developer Experience, I am focused on making the Handsontable data grid library and HyperFormula calculation engine easier to use for both developers and AI coding agents.

Coding is evolving rapidly, and developer workflows are changing with it. I am excited to help shape this transformation, work closely with our community, and make our tools more powerful, intuitive, and AI-ready.

## Head of DevRel @ Appsmith

I found Appsmith because I kept hitting limitations in other platforms. They found me because I kept pushing the limits of their platform.

I joined Appsmith in 2022 and enjoyed an amazing 4 years learning from an outstanding team of engineers.

## CLIENT TESTIMONIALS

Joseph is an example of your ideal consultant! He was extremely helpful in developing solutions, providing support, training internal resources, referring additional talent, and overall communicating throughout the life of our contract. I would highly recommend Joseph for any project as he is an invaluable resource and brings far more to the table than just executing on a project deliverable.

Nieko

UpWork Client

Can't believe how lucky I got finding Joseph! I've worked with many freelancers over the years, and a handful of mentors on codementor.io. Never have I worked with someone who has the knowledge, the ability to explain, the energy and enthusiasm, the creativity, and the preparedness all wrapped in one. What has stood out most to me, however, is his sincere dedication to my project despite the fact that he's "only" a contractor. Don't waste your time looking any further- if AppSheet is your platform, Joseph is your man.

Paul

UpWork Client

Joseph has developed a system that has transformed business. We have a very complicated internal system that needed a solution to ensure we executed all action items in our customer profile. His professionalism, organization, and knowledge of AppSheet is beyond reproach. He is extremely prompt with answers or solutions to any questions or problems I have. He is extremely creative in finding solutions to my any requests that I have. We will be using his services on a permanent basis.
