Software Development in Cincinnati & Dayton

Custom software, web applications, integrations and platforms built by a senior team serving Cincinnati and Dayton since 2006. Fixed-scope proposals, thoughtful architecture and people who stay accountable from discovery through launch.

What we build

Software built around your business

From a single integration to an end-to-end platform covering customer intake through fulfillment.

Custom web applications & SaaS platforms

Purpose-built applications and subscription platforms shaped around your customers, business rules and growth. We plan the foundations as carefully as the screens people use.

Client portals & dashboards

Secure places for customers to manage accounts, share information and follow progress, with dashboards that give your team a clear view of the work and data that matter.

API development & system integrations

Connect CRM, ERP, scheduling, payments and operations systems. We build APIs and third-party integrations with clear data flows, access controls and practical error handling.

Mobile applications

Mobile experiences for customers and teams, scoped around the devices, access requirements and workflows your business actually needs.

Workflow software

Business applications that replace disconnected spreadsheets and repetitive handoffs with consistent workflows, appropriate permissions and usable reporting.

Healthcare-capable software

We sign BAAs and plan HIPAA-aware architecture that keeps PHI out of the public website and CMS. Projects can include EHR integrations, telehealth solutions and mobile health apps, with data handling and responsibilities agreed during discovery.

Why HDM

Senior experience. Clear accountability.

Founded in 2006, HDM brings 20+ years of experience and 300+ website builds, alongside custom software, integrations and portals. We help businesses move from disconnected systems to software that fits how they operate.

Senior team members have worked on data and backend systems for a Fortune 7 healthcare company. Those products live behind enterprise logins, not in a public portfolio. That experience informs how we approach architecture, permissions and sensitive data.

Based in Springboro, Ohio, we work directly with businesses across Cincinnati and Dayton, and as a white-label development partner for agencies. You get senior people, clear communication and a scope you can make decisions around.

How we work

A deliberate path from discovery to launch

Know what is being built, what it costs and who is responsible at every stage.

  1. Discovery

    We learn your business, map workflows and data, review the systems you rely on and identify constraints before proposing the build.

  2. Scoped fixed price

    You receive a proposal with defined deliverables, assumptions, milestones and one agreed price. Changes outside that scope are discussed and approved separately.

  3. Senior implementation

    Experienced team members design and build the application, with regular check-ins and working increments you can review.

  4. Human code review & security

    Human code review, access controls and careful data handling are part of delivery. Architecture and documentation are structured to support enterprise security reviews; this is not a claim of SOC 2 certification.

  5. Launch & ongoing support

    We plan testing, rollout and handoff with you, then agree on ongoing support, maintenance and future improvements so ownership stays clear after launch.

Technologies

The right foundation for the scope

We choose the stack around your existing systems, security requirements and long-term ownership.

  • Next.js
  • Supabase
  • PostgreSQL
  • Microsoft Azure
  • REST APIs and third-party integrations
  • Figma for design handoff
