Your next app needs AI. Let's architect it right.
Don't let AI become the most expensive experiment your product never shipped.
SCHEDULE A MEETINGMost AI integrations fail before they launch
Burning budget on AI that never ships
- Teams spend months experimenting with AI features that never make it to production.
- Without the right architecture, AI becomes the most expensive line item with nothing to show for it.
AI bolted on, not built in
- Wrapping an API call around a language model is not an AI product.
- Without proper architecture, you end up with brittle integrations that break under real-world usage.
No AI expertise on the team
- Your developers are great at building apps, but AI architecture is a different skill set.
- Agentic workflows, model orchestration, and tool integration require specialized knowledge.
AI that works in production, not just in demos
Architecture-first AI
- AI features that are designed into your system from the ground up, not patched on after the fact.
- Agentic workflows, tool integration, and model orchestration built on solid foundations.
Production-ready from day one
- No prototypes that fall apart under real traffic. Every AI feature is built to handle production workloads.
- Proper error handling, evaluation, and monitoring so your AI actually works when users depend on it.
End-to-end delivery
- From frontend to agentic backend, the entire stack is covered. No handoffs, no gaps.
- 9 years of fullstack experience means your AI-powered app ships complete, not half-built.

Just like the last time we engaged with him, Xavier helped us out reliably and efficiently. He specifically supported us in improving our unit and integration tests integrating emulators for our backend services into the test process.-- Johannes Stiehler

Xavier is a talented frontend developer, who supported our project for months and took our ideas from a google doc to an actual product/prototype. Xavier is fun to work with, a great team player and very accountable. We are a remote team, and Xavier just fit right into our team culture.-- Karan Dhingra

Xavier is a talented software engineer who took our React/Redux project from 0 to 100 in record time. Xavier was able to quickly and expertly solve every problem we came across throughout the development process, which has resulted in a stellar end product. He has an eye for design and UX that sped up development significantly.-- Jake Glass

Xavier was an invaluable part of our team, using his React expertise to bring pixel perfect screens to life as promised. Of all of the React developers we've worked with - on Upwork and otherwise - Xavier was one of the very top engineers with whom we've been lucky enough to have on our team.-- Alli McKee

Xavier is not a typical fly-by freelancer, his commitment to success of our project was amazing. Xavier's technical skills especially in React application development can be compared to a world class developer. His methodical approach to writing code resulted in a easily maintainable code that my company can continue to use it as an asset going forward. Xavier's work ethics is one of the best I have seen across all kinds of staffing models, he is very direct and gives honest feedback on ideas that he thinks will work or not work.-- Sanjay Mahadi

Xavier was an outstanding addition to the team. Easy to work with, great communication. We asked Xavier to help us with our complex Node.js web app working with React, Relay, and GraphQL. He ramped up on our application very quickly and immediately added value to the project... It was as if he had been a member of the team all along. Worked efficiently and followed development processes like a true professional. We would definitely hire Xavier again in the future-- Adam Tratt
