Karen Ortiz
I design and build AI-powered web products, from architecture to the last pixel.
Software Engineer focused on Product Engineering & Web Experiences. I design systems, components, and agents that connect UX, infrastructure, and AI into production-ready products.
- Web architecture and development with Next.js, Astro, TypeScript, and decoupled stacks.
- Token-first design systems and npm libraries for distributed product teams.
- AI integrations (MCP servers, LLMs, automation) that enable non-technical teams.
Product essays
In-depth pieces for hiring managers and engineers: readable in plain language, technical when you want the detail.
Client work
Shipped products and platforms where I led product thinking, UX, and engineering.
I bridge engineering without the usual handoff friction.
Senior product thinking
I design with business goals, user behavior, and technical constraints in mind.
Built to ship
My work translates cleanly into systems, components, and production-ready code.
AI with intention
I use AI where it improves workflows, tools, or product value.
Low-friction collaboration
I work fast with founders, designers, and engineers across the full product cycle.
Product & UX Engineering
I define, design, and build new features or full products. Light research, UX/UI, prototypes, and fullstack development in the same flow.
Modern Web Experiences
I build sites, dashboards, and web apps integrating APIs, databases, and external services ready for production.
AI-Driven Interfaces & Workflows
I design and build context-aware interfaces where AI makes sense, turning it into agents and automations that improve your product and internal processes.
Design Systems & Internal Tools
I create or evolve your design system, component libraries, and internal tools so product, design, and dev work on the same foundation.
UX & Conversion Improvements
Data-driven optimization for active products. I analyze user flows, performance bottlenecks, and retention metrics to deploy targeted improvements.
Architecture & Tech Guidance
I guide founders and small teams to make good stack, architecture, and integration decisions. Thinking about what you'll need in 6 to 12 months, not just the next sprint.
Trusted by design-led companies & engineering teams
I partner with teams across LATAM, the US, and Europe that take product design, architecture, and applied AI seriously.

About me
Companies partner with me for my product sense + technical instincts.
I connect product thinking, UX, and engineering, so decisions make sense for users, the business, and the codebase.
I care about the craft, from the architecture and design system to the final micro-interaction in production.
I define scalable systems (design tokens, components, internal tools) that help teams move faster instead of starting from scratch every time.
I use AI with intention, turning it into workflows, agents, and tools that actually help teams ship better work.
