01 · Founder-led

Direct access.
Clear accountability.

I'm Steven Hagene, founder, product and technology lead, and Marine Corps veteran. I lead every engagement directly and bring in trusted specialists when the project calls for them, giving you clear accountability and the right expertise for the work.

No account managers or layers between you and the work. I stay directly accountable and bring in trusted specialists when a project calls for them.

My stack: Next.js, React,Node.js, Flutter,Firebase, and AI/LLM integration. I've shipped legal-tech platforms, healthcare product suites, e-commerce systems, and my own apps on Google Play.

Whether you're a founder building an MVP, a business modernizing operations, or a government buyer needing reliable software, I deliver solutions that actually ship.
