Technical and operational disorder is the primary barrier to growth.

Too often, companies waste precious time due to poorly connected tools or accumulating technical debt. My role? To organize, structure, and build.

An entrepreneur at heart and a developer by training, I work at the intersection of Code (for performance) and No-code (for agility). I help startups and SMEs transform their ideas into robust products and their manual processes into automated systems.

What I bring to your project:

Full-stack Web Development: Creation of modern, scalable, and user-centric applications (React, Next.js, Node.js).

Architecture & Ops: Audit of your processes and implementation of intelligent automations (Make, Airtable) to free up your teams' time.

Product Vision: I don't just "push code"; I ensure every feature serves your business objectives.

Why work with me? I like things to be well-organized. My approach is iterative, transparent, and focused on efficiency.
