Cosairus

Embedded engineers who fix the systems you already run

Cosairus is a custom software firm that places experienced engineers inside a client's team and codebase. The company says it improves the software a business already depends on, using AI-assisted development, rather than rebuilding it from scratch or ending the engagement with a document. Its engineers work in the client's own tools and delivery environment.

Problems the firm addresses

The company describes several situations it is called in for. These include manual workflows that slow teams down, systems that cannot share data reliably, legacy software that is hard to improve, reports that leaders cannot trust, AI projects with no practical path into the business, and data foundations that must scale. For each, it says it replaces repetitive handoffs with purpose-built applications, connects platforms through secure integrations, or designs the data layer so that it keeps up with growth.

Six service areas from AI to support

The AI service identifies useful opportunities, builds intelligent features and integrates models into real workflows, with security and governance in mind. On the application side, responsive websites and browser-based platforms sit alongside native or hybrid apps for iOS and Android. Integrations connect internal systems with third-party services, CRMs, ERPs and payment processors, so that data moves securely and consistently. Database work covers architecture, tuning, migrations and reporting. Business intelligence covers custom dashboards and analytics. Support and maintenance add framework upgrades and security improvements to extend the life of a system.

Embedded modernization in practice

The embedded engineering work is short-term and scoped, and the company says the client's team stays in control of the work. It uses AI-assisted code analysis, test creation and documentation recovery, along with refactoring and workflow automation inside live systems. The aim, in its words, is better test coverage, documented code and lower release risk without a full rebuild.

Past projects

Past work includes a staffing application moved off an older platform, a secure image transfer app for Android and iOS that handled patient medical records, and an electronic medical records, appointment and doctor scheduling system for a medical facility, built for both mobile and the web. The company works with SQL Server, ASP.NET and Entity Framework, among other tools, and says it delivers software at regular intervals so that clients can give feedback early.
