About
Work by Robert Kaltenbach under Two Tree Creative — shipped projects, how problems get framed, and what collaboration looks like on real builds. Open to freelance, full-time, and contract conversations when the fit is right; client engagements run through Two Tree.
Robert is a developer, designer, and operator with 10+ years building software and running businesses. He owned multi-location companies and built the systems behind them — POS, loyalty, internal tools, and customer-facing apps. That background shows up as an insistence that software survive contact with reality, not just demo well.
Engagements focus on AI-first products, web and mobile apps, and rescue work on codebases that need a steady hand. The practice stays small and senior-led — no junior bench, no theater. Freelance availability opens when there's a clear problem and room to execute; employer and recruiter outreach is welcome for the right role. Use the contact form below either way.
