Health Data Provider Performance Portal

Partnering with Onpoint Health Data, we created both an administrative portal and user portal for accessing healthcare "All Payer Claims Data (APCD)". The portal is used by Insurers, Doctors Offices, Medical Groups and other organizations in many states to analyze and asses their performance on medical measures. From 2017 to 2020, we rolled out this platform to multiple state APCD entities.

The Provider Performance

Portal is an advanced cloud based analytics platform that meets HIPAA and HITECH security and legal requirements while providing users with a modern web environment that meets the high expectations of consumers today - responsive for devices, extremely fast and straightforward to use.


  • Improve health care price transparency
  • Assist patients, providers, hospitals, clinics, insurers and medical groups to make informed choices about care
  • Enable purchasers to identify value, build expectations into their purchasing strategy, and reward improvements over time
  • Promote competition based on quality and cost

Thomson Reuters Eikon Messenger

Thomson Reuters Messenger is a widely used instant messaging platform used across the world by tens of thousands of users. It is deployed both inside of the Eikon financial information platform and as a standalone Windows application.

Working closely with the Thomson Reuters collaboration group we helped rewrite the front-end and back end of the instant messaging platform. As well as doing core development and design for

the re-write we helped hire and manage a team of developers to build the HTML5 front end, iPhone/iPad application and eventually the Go backend to replace Microsoft Live Communication server. After successfully launching the front end of the project with the Eikon 3.0 relaunch we transitioned management of the project to Thomson Reuters employees.

As part of this project we were able to open source some of our work, some of the first open source code produced at Thomson Reuters - this included a Go NTLM library written from scratch -

Parathyroid Website

We worked with the Norman Parathyroid Center to transform their 1998 style Microsoft Front Page website to a new CMS and a new responsive design - while maintaining 100% of their high SEO rankings. This required careful tradeoffs in what we were able to do with the design of the existing content, carefully staging and managing the changes across the site while monitoring the analytics and rankings.

Feedback summary: 

Square Mill Labs delivered an easy to use platform that has received a lot of positive feedback based on its sleek design. Their team communicated directly with partners, ensuring that there were no miscommunications. They’re flexible partners who go above and beyond to meet project needs.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.


Introduce your business and what you do there.

At the time I worked with Square Mill Labs, I was the chief information officer at a health data company.


What challenge were you trying to address with Square Mill Labs?

We outsourced several different software development projects to Square Mill Labs.

In the most significant project that we worked on with them, they developed a performance reporting portal. The platform allows healthcare providers, plans, and payers interested in health care quality to log in and see various healthcare quality metrics. Then users can search for metrics across different groupings of data.

For example, a physician could log in and see their quality metrics compared to their peers, or compare their work to a statewide average. Instead of focusing on fees, this platform focuses on the quality of the services provided.


What was the scope of their involvement?

For the performance reporting portal, Square Mills Labs used several different technologies to develop this database, including two different databases—Amazon Aurora and Amazon Redshift. Then they used Ruby on Rails for the frontend, and probably JavaScript, HTML5, and CSS.

We provided the high-level requirements, but they came up with the initial design themselves. Then we would provide input or feedback. Basically, we built the data components and they would feed that into the application so it could easily be consumed by users.

What is the team composition?

We had 2–4 people on our team depending on what phase of the project we were on.

How did you come to work with Square Mill Labs?

I’ve known one of the co-founders on Square Mill Labs for a long time. Initially, we reached out to them when we were looking to build a new website. They created a proposal and were selected ver four other web development companies.

Our business relationship evolved and we asked them if they were interested in partnering on this new application. Naturally, they were a good fit for that product.

How much have you invested with them?

I would put it a little over $1 million.

What is the status of this engagement?

We began working together in November 2015 and the collaboration is still ongoing.


What evidence can you share that demonstrates the impact of the engagement? 

When I stopped working with them, there were five clients using the product and we had given them surveys to provide feedback. I don’t have access to those results, but just by talking to clients and users, I know that there was a lot of positive feedback. They liked the simplicity of the design and its usability.

How did Square Mill Labs perform from a project management standpoint?

They were always available through Slack, email, or telephone. They were always reliable and available when we needed them, so their communication was great. They met al expected deadlines and milestones unless the scope had changed. Overall, the experience was very positive.

Their team is a little smaller than other big development shops, so they don’t have project managers. Instead, we talked directly to the people doing the work, which I actually think was really helpful. In my opinion, it was advantageous to communicate with the team directly because there were no miscommunications.

What did you find most impressive about them?

They're really savvy with design. They put together some really solid design patterns there. Their efficiency is amazing and they were able to develop a lot in a short amount of time.

Their other strength was the team’s flexibility. Things change all the time during development projects, but they never got frustrated. They would just roll with it. They were accommodating and would execute whatever our clients needed.

Are there any areas they could improve?

Sometimes, when things got busy, they didn’t have the bench strength need to keep up with the work. However, they were able to tap into their network of developers and get the resources we need.

Do you have any advice for potential customers?

You should have a good idea of what you want to accomplish ahead of time and have the internal resources to meet the project’s needs. That’s how you’ll get the most out of working with them.

Overall Score
  • 4.5 Scheduling
    They go the extra mile to meet deadlines. The only reason I’m not giving them a 5 is because of the limits on their capacity.
  • 4.5 Cost
    Value / within estimates
    Their hourly rate is high, but the value is tremendous and their efficiency makes up for their rate.
  • 5.0 Quality
    Service & deliverables
    We’ve worked on 3 projects with them, and they always delivered a high-quality product with a slick, user-friendly, and intuitive design.
