Ship AI that works in production
Agents, reinforcement-learning data infrastructure, and on-device models. Designed, built, and shipped to real users, not left in a notebook.

Josh Jaquez
I build products, end to end.
Applied AI and agentic systems, built on deep full-stack product work: on-device macOS apps, data infrastructure, and web platforms, shipped from seed to Series D.

What I do
What I can do for you
Three ways I help teams and founders turn ideas into shipped, production systems.
Take products from idea to users
Full-stack engineering across macOS apps, web platforms, backend services, and AWS, with the production discipline that keeps software dependable.
Make the right technical call
Architecture and modernization reviews, AI feasibility, and build-vs-buy guidance, so you invest in what is actually worth building.
How I work
- I work across product, AI/ML systems, and infrastructure, with fewer handoffs, faster iteration, and stronger coherence between teams.
- Experience from seed-stage startups to Series D companies informs how I trade speed against rigor.
- Production discipline: observability, staged rollouts, and incident ownership are design requirements, not afterthoughts.
- Clear communication in discovery, scoping, and reviews, with founders, product teams, and external partners.
