Off-the-shelf software rarely fits the way a hospital, clinic, or digital health company actually operates. Zerosums Technologies builds custom medical software that fits your clinical workflows, integrates with the systems you already run, and meets the compliance bar that healthcare demands. Our development team works alongside clinicians, administrators, and IT leadership to design software that solves real operational problems — not generic templates retrofitted to healthcare. Our core development work includes EHR/EMR module development and customization, patient portals for appointment scheduling and secure messaging, telehealth and virtual care platforms, practice management and billing systems, remote patient monitoring (RPM) applications that connect to wearables and home health devices, and clinical decision support tools. Every application we build starts with a security and compliance review — data encryption in transit and at rest, role-based access control, audit logging, and HIPAA-aligned architecture from day one, not bolted on after launch. Interoperability is built into everything we develop. As the same team behind Zerosums' HL7 and FHIR integration practice, we connect new applications to Epic, Cerner, MEDITECH, athenahealth, and InterSystems IRIS/HealthShare environments using HL7 v2 interfaces and FHIR R4 APIs. That means a new patient portal or RPM application doesn't become a data island — it exchanges data with your EHR, your reporting systems, and your care coordination platforms. On the infrastructure side, we build cloud-native applications deployed on AWS, Azure, or Oracle Cloud, containerized with Docker and orchestrated with Kubernetes where scale demands it. CI/CD pipelines automate testing and deployment so updates ship safely and frequently. This pairs directly with our cloud and DevOps engineering services for organizations that need both the application and the infrastructure it runs on built and maintained by the same team. We also modernize legacy healthcare applications — re-platforming aging desktop or on-premises systems to secure, cloud-hosted web and mobile applications without disrupting the clinical operations that depend on them. Whether you're building something new or rescuing a system that's become a liability, Zerosums Technologies provides the healthcare software development expertise, compliance discipline, and integration depth to get it right.
