About

I build apps (Mobile/Web/Desktop) that don't crash, don't rot, and don't require babysitting. I've led teams, owned codebases, cleaned up messes, and shipped for indie startups, fintechs, and solo ventures. I've spent 10+ years building beyond apps: SaaS tools, mobile games, gamified UX, and full-stack products that actually ship. Currently open to consulting, partnerships, or work that respects the drive to build something great. Message me on LinkedIn, email me, or book me via the link in bio.
