🚀 I build complete AI products end-to-end — from idea to a working MVP you can put in front of users and investors. Most projects need three people: a product manager, a developer, and a designer. With me, you get all three in one. I work out the product logic, build the actual thing, and polish the visuals to a level you'll be proud to show — no friction between contractors, no "broken telephone" between them. ⚡️ Fast isn't a promise — it's how I work: Small products and prototypes — a couple of days Mid-size MVPs — 1–2 weeks Larger products — a month and up The speed comes from pairing AI tooling (Claude Code, Codex, Claude Design, Lovable, OpenAI, Figma) with 8+ years of product experience — I know what belongs in an MVP and what to cut, so we don't burn time or budget. 🎯 What you walk away with: ✔ A working MVP — not a pile of mockups and docs ✔ Thought-through product logic — flows, priorities, focus on what creates value ✔ Clean, polished visuals and UX ✔ AI features that actually work: LLM integrations, prompt engineering, guardrails, feature-quality evaluation ✔ A launch, real user validation, and a product ready for the next iteration 🛠 Under the hood: Development & AI: Claude Code, Codex, OpenAI, LLM integrations, prompt workflows, provider benchmarking, LangSmith Design & visuals: Claude Design, Figma, Miro Product & analytics: Amplitude, Mixpanel, GA4, A/B testing, cohort analysis, funnels 🏆 A bit of background: 8+ years in product: SaaS, AI, B2B/B2C startups Scaled products from 0 to $1M ARR 1 successful exit Dozens of launched MVPs (web & mobile) Upwork Top Rated, 100% Job Success, 3000+ hours Strong on metrics: retention (D1/D7/D30), churn reduction, ARPPU, conversion to subscription I measure success not by "tasks closed" but by whether the product works and its metrics grow. 💬 Send me a few words about your product and what you need built — I'll offer a free 30-minute consultation and sketch out how we can ship it fast, without the bloat.

Most products don't lose users because the design is bad. They lose them because nothing brings people back. No habit, nothing worth returning for. That's the problem I work on. I combine UX design with behavioral psychology and gamification to build products people keep using, not ones they try once and forget. Across 880+ hours on Upwork with a 100% Job Success score, I've helped SaaS platforms, EdTech tools, health apps, and mobile products in Europe, North America, and the Middle East turn one-time signups into daily users. My approach leans on the Octalysis framework, onboarding psychology, and retention-focused UX, with certifications from Wharton, McKinsey, HEC Montréal, Google, and IBM behind it. What I usually deliver: • UX audits that pinpoint where users drop off • Onboarding redesigns that cut friction and lift activation • Gamification systems that build habits, not just badge counts I'm based in São Paulo and work comfortably across North American and European time zones, so collaboration stays in real time. Top Rated, 100% Job Success. If your product gets users but struggles to keep them, send me a message and we'll find where your retention is leaking.
