Custom Software Development

Broad Technology Expertise

.NET is our cornerstone, but it’s just one thing we do.

You won’t need any technical experience or software development knowledge to work with us. You can trust us to lead the way. However, if you’re technical and need to talk programming languages, APIs and frameworks, we can do that too. Here’s a sampling of what we do:

.NET | C# | MVC | RAZR | VB.NET | VB | PHP | JavaScript | jQuery | Angular JS | NodeJS | HTML5 | CSS |  Bootstrap | jQuery mobile | JSON | XML | XSLT

Integrations and Third-Party Tools

We love connecting software.
Designing and building efficient, accurate, and reliable solutions typically requires multiple system integrations. We already have a large portfolio of data API integrations that make business-critical functions easy, and are more than comfortable diving into more. Here are just a few that are already in our wheelhouse:

  • EDI, RESTful, SoaP, API, JSON
  • Tax systems
  • Payment gateways
  • Shipping
  • CRMs and ERPs
  • Marketing and analytics

Microsoft Azure

IT & Cloud Applications

Data security and scalability matter as much as the code.
Some development shops build great web applications, but fall short when it comes to deploying it to the cloud. 

As a Microsoft Partner, Azure is our backyard. We use a full spectrum of Azure services, including: Service Bus, Web Apps, Virtual Machines, Blob/File Storage, Encryption, Virtual Networks/Subnets, Network Security Groups, Virtual Gateways and site-site VPN, and CDN.

When you partner with Acumium, you’ll sleep easy knowing your servers can withstand Super Bowl-level traffic, and beyond.

Let's build something that takes your business to the next level.

Whether you need a development partner to help modernize a legacy software system, build a custom business application from scratch, or take your idea to market via a commercial software product, we’re the right partner to tackle the challenge.
