Case Studies
Here's what I've been working on and how it came together.
invoo: From Idea to Multi-Platform Product
Co-founded an invoicing tool for Spanish freelancers. Built web and mobile from scratch in 2 months. 150+ waitlist signups, zero ad spend. Launched May 2026, live with the first cohort.
DataCamp Paywall: 50% Conversion Lift From Deleting a Feature
65% of users bounced on a screen before ever seeing the paywall. I deleted it entirely and lifted conversions by 50%.
Deck: The IDE I built because nothing on the market fit
Existing IDEs are either cluttered with dev features I don't use or too heavy on agentic workflow. I wanted something simple: read code files, render Markdown nicely, and run Claude Code in multiple terminals side by side. So I built it. Electron, React, TypeScript, CodeMirror, xterm.js. Actively maintained.
DataCamp Mobile Home: From Content Overload to 7% Course Lift
I bet that users think in actions, not courses. Restructured the entire home screen around learn/practice/review instead of course types. Bounce rate dropped 10%, course engagement rose 7%.
ai-org: scaffolding I clone into every new project
A reusable Claude Code plugin that ships four portable layers into any repo: agents with a point of view, skills with explicit rules, commands that trigger workflows, and product knowledge the AI can actually read. Running in four of my active projects, plus designers at DataCamp using it to ship code they wouldn't have attempted alone.
