Consulting
Engineering services for organizations building secure, maintainable software. We work with startups, established companies, government agencies, and prime contractors on advisory engagements and hands-on contracting.
Leadership
Engagements are led by A3RN's Founder & Principal: 20+ years of industry experience across telecommunications, financial services, adtech, and startups. PhD from a top-10 US research university, with publications in top-tier peer-reviewed venues, granted patents, and industry conference speaking engagements.
Small, senior team. Direct communication, no intermediary staff, no layers of project management. We take on engagements where we can do the best work — which means we sometimes say no. If that sounds like a fit, get in touch.
Consulting
Advisory engagements focused on architecture, security, and engineering practice. Typical outcomes include system design reviews, security audits (especially for apps handling sensitive user data), and guidance on moving teams toward more maintainable codebases.
Contracting
Hands-on build work when you need execution, not just advice. Mobile and web applications, backend services, end-to-end encrypted systems, and integrations. Fixed-scope projects or embedded engagements with your team.
Public Sector
We're structured to take on public-sector engagements and prime subcontracting relationships. See our capability statement for core competencies, differentiators, and past performance.
