About this gig

Build a secure, maintainable SaaS or business web application with direct founder-led engineering.

I am the Founder and CEO of Neufology, where I lead architecture and hands-on delivery across more than 41 product surfaces in SaaS, healthcare, retail, infrastructure, and security.

I can deliver React or Next js responsive interfaces, Node js or Python backend APIs, PostgreSQL, MongoDB, or MySQL data models, authentication, role-based access, tenant-aware workflows, dashboards, admin tools, integrations, automation, testing, deployment, documentation, and handover.

My work includes secure dashboards, API-heavy platforms, cloud products, vulnerability workflows, real-time systems, and operational software.

Please message me before ordering with your users, core workflow, required integrations, current assets, and deadline. I will recommend a practical milestone and package.
