Building What's Next
At the frontier of design, development, and AI, I turn ideas into real products that delight users from day one and are ready to grow.

Book a callI focus on what early-stage teams need most — moving fast, keeping things clear, and building products that are ready for real users and investors.
I work in focused sprints so you can launch, test, and show progress without long waits or wasted cycles.
Every flow and interface is designed to be intuitive and usable, making it easier for early users to adopt and stick with your product.
Your product is built with a lean, scalable tech stack (React, Next.js, Supabase, Tailwind), and I use AI where it adds value to speed up delivery and keep quality high.
I stay close to founders, helping you make smart product calls and keeping momentum as your startup grows.
From MVPs that win investor trust to tools that attract early users, I design and build digital products that move founders forward.
Prototypes and polished MVPs that bring your vision to life and give investors something real to believe in.
Marketplaces, communities, and networks that make it easy for people to meet, share, and transact.
Intuitive apps designed for clarity and speed, helping you test traction with your first real customers.
Custom dashboards and internal tools that replace messy spreadsheets, automate processes, and keep teams aligned.
I choose tools for speed, reliability, and room to grow. Here are my go‑tos and how I use them.
Where ideas come to life
Modern tools to explore ideas quickly, test concepts, and create clear user flows.
From sketch to MVP
Frameworks and infrastructure that make products fast, reliable, and ready to grow.
Adding intelligence to your product
Practical AI and new technologies that add smart features and automation without extra complexity.
We start by making the idea concrete. Together we define what matters most, map user flows, and create a prototype. If you already have designs, I review and adapt them to fit the build.
I develop the core features with a lean, modern stack (React, Next.js, Supabase, Tailwind). AI tools are used where they can speed things up or improve quality. The focus is always on building something functional and reliable.
Your product goes live and is ready for real users. Tracking and feedback are built in so you can see what's working, learn quickly, and share progress with investors or your team.
After launch, you choose how to move forward. Many founders continue with me on a monthly sprint retainer, where each sprint delivers tangible improvements — new features, UX refinements, or growth experiments.
Packages designed to help you launch quickly and grow with confidence.
A clear, testable product vision — ready for investors or development.
A working MVP you can launch with users, built on a modern stack.
One partner handling design and development, from idea to launch.
For founders with a live product, momentum is everything. Growth Sprints give you consistent progress in focused two-week cycles. Ship new features, refine UX, and scale smarter without the overhead of a full team.
I'm Xavi, a product builder with a background in design and development, and a master's degree in UX. My focus is on helping founders move from early concepts to working products by blending thoughtful design with reliable code.
I enjoy the entire journey. From shaping an idea into a clear prototype, to building an MVP that real users can try, to refining the product based on feedback. My approach is practical, structured, and always centered on creating products that feel usable and valuable from day one.
