Your MVP works, but isn’t ready for production.
I’ll assess the existing application, identify launch blockers, stabilize critical workflows, address security and reliability issues, and establish a practical path to production.
Senior judgment. Hands-on implementation.
Senior Software Engineering & Architecture for Healthcare and SaaS
Hands-on engineering for companies that need to launch, stabilize, modernize, or scale critical software.
Ajilesoft provides senior-level software architecture and hands-on development for healthcare technology and SaaS companies. I work directly with your team and codebase to solve difficult technical problems, improve reliability and security, modernize applications, and get software into production.

Problems I solve
When you need senior engineering judgment — and someone who can implement it.
Your software needs modernization, not a rewrite.
I’ll help determine what should be preserved, what needs improvement, and where targeted modernization will produce the greatest benefit without unnecessarily replacing working software.
You need experienced healthcare engineering.
I bring decades of experience building healthcare applications involving medical imaging, clinical workflows, interoperability, security, privacy, and regulated environments.
You have an architecture problem that also requires coding.
I don’t stop at diagrams and recommendations. I can design the solution and personally implement the APIs, services, database changes, integrations, web applications, cloud infrastructure, and deployment changes needed to deliver it.

Decades of Healthcare Software Experience
My experience spans medical imaging, radiology, pharmacy, ophthalmic imaging, clinical workflows, interoperability, and healthcare SaaS. I’ve worked with DICOM-based systems since the 1990s and have designed and developed cloud-native healthcare platforms, REST APIs, secure data-exchange systems, annotation and visualization applications, workflow software, and AI/ML-enabled imaging solutions.
That background informs both the engineering work and the security, privacy, interoperability, and operational considerations surrounding healthcare software.

How I work
Senior expertise without adding another layer of management.
When you engage Ajilesoft, you work directly with me. I personally assess the problem, design the solution, and perform the engineering work.
I favor practical solutions over unnecessary rewrites, architecture for architecture’s sake, or introducing technology simply because it’s new. The objective is dependable software that solves the business problem and can be maintained after the engagement.
Preserve What Works
Modernization doesn’t automatically mean rebuilding.
Solve the Highest-Value Problems First
Separate critical issues from important improvements and things that can wait.
Design and Implement
Architecture decisions are grounded in the realities of actually building and operating the software.
Ways to Work Together
Technical & Launch-Readiness Assessment
A focused assessment of an application, architecture, or AWS environment, with findings, risks, prioritized recommendations, and a practical implementation roadmap.
Hands-On Engineering
Focused implementation for stabilization, modernization, cloud migration, integrations, new capabilities, or difficult technical problems.
Fractional Technical Leadership
Senior architecture and technical leadership without a full-time executive, with hands-on engineering available when needed.
Best fit
Who I Work Best With
I work best with healthcare and SaaS teams that have an existing product, a difficult technical problem, or a need for senior architecture combined with hands-on implementation.
- Healthcare and healthtech product companies
- SaaS founders preparing an MVP for production
- Teams stabilizing an existing application
- Organizations modernizing workloads on AWS
- Engineering teams needing senior architecture help
- Companies needing fractional technical leadership
Founder & Principal, Ajilesoft
Rob Williams
I’m a software architect, hands-on developer, and technology executive with decades of experience building commercial software, particularly in healthcare technology. My career has included founding and scaling software companies, leading engineering organizations, architecting healthcare platforms, and personally developing production software across cloud, backend, frontend, and data technologies.
Today, through Ajilesoft, I work directly with companies that need senior technical experience without giving up hands-on engineering.
