"I don't just write code — I build products that solve real problems for real people"

I'm a Full Stack Developer from Florianópolis, Brazil, with 2 years of professional experience building products that matter. I specialize in turning complex business problems into simple, scalable solutions.

💡 What drives me:
I believe technology is just a tool. What matters is understanding the problem, the market, and the people you're solving for. That's why I combine technical execution with business thinking to build solutions that create real impact.

🚀 My approach:
I don't wait for instructions. I identify real problems, build MVPs fast, test with real users, iterate based on feedback, and ship products that people actually need.

🎯 Current focus:
Building solutions in fintech, Web3 payments, and emotional wellness — three markets with massive growth potential and underserved users.

🎯 The Problem:
Brazilian startups want to accept cryptocurrency, but integration is complex, expensive, and requires deep blockchain knowledge. There's no simple API with multi-wallet support and automatic payment distribution.

💡 The Solution:
A payment API for Solana that makes accepting crypto as easy as using Stripe. Startups can integrate with 3 lines of code and automatically split payments across multiple wallets (founders, investors, employees, contractors).

📊 Market Opportunity:

• Crypto payments in Brazil growing 150% year-over-year
• 30% of Brazilian startups want to accept crypto but don't have the technical capability
• Stripe and Coinbase don't offer localized Web3 solutions for Latin America

💰 Business Model:

• Transaction fee: 1-2% per processed payment
• Target: Process R$1M/month = R$10-20k MRR
• Second vertical: White-label solution for fintechs and payment processors

🛠️ Tech Stack:
Solana Web3.js Node.js TypeScript PostgreSQL

🔥 Why it matters:
Web3 is the future of payments, but it's still too complicated for 99% of companies. This bridges the gap between crypto's potential and real-world usability.

📈 Current Status:
MVP in development. Targeting first pilot customers by Q2 2025.

🎯 The Problem:
Mental health is a global crisis. 80% of people don't understand their emotional patterns, and traditional mental health apps require manual input, discipline, and effort that most users don't have.

💡 The Solution:
An emotional wellness app that analyzes your Spotify listening habits to automatically map your emotional patterns over time. No manual input. No invasive questions. Just insights based on what you're already doing — listening to music.

📊 Market Opportunity:

• Digital mental health market: $6 billion globally (growing 25% annually)
• Spotify has 500 million users worldwide, 70 million in Brazil alone
• Competitors (Headspace, Calm, BetterHelp) require active engagement — Emotify is passive

💰 Business Model:

• Freemium: Free basic emotional reports
• Premium: R$19.90/month for advanced insights, mood tracking, and personalized recommendations
• Target: 10,000 users in first year = R$200k ARR at 10% conversion

🛠️ Tech Stack:
JavaScript React Spotify API Python Data Analytics Machine Learning

🔥 Why it matters:
Everyone listens to music. This turns passive listening into actionable emotional intelligence without requiring users to change their behavior.

📈 Current Status:
Beta version with real users testing. Refining emotion categorization algorithms based on feedback.

🎯 The Problem:
15 million MEIs (micro-entrepreneurs) in Brazil are drowning in financial chaos. They don't understand cash flow, taxes, or profitability. Traditional finance apps are too complex and require discipline they don't have.

💡 The Solution:
A WhatsApp bot powered by AI that manages finances through natural conversation. User texts: "Gastei R$200 no mercado" → System automatically categorizes, alerts about overspending, and projects cash flow for the month.

📊 Market Opportunity:

• 15 million MEIs in Brazil (growing 20% annually)
• Financial management market for SMBs: R$2 billion in Brazil
• Competitors (Conta Azul, Nibo) use complex dashboards — 80% of MEIs never log in after first week
• WhatsApp has 99% penetration in Brazil — users are already there

💰 Business Model:

• R$29/month per MEI (affordable entry point)
• Goal: 1,000 paying customers = R$29k MRR in first year
• Unit economics: R$5 CAC (WhatsApp virality) vs R$348 LTV (12-month retention)

🛠️ Tech Stack:
Node.js Twilio WhatsApp API Claude AI Supabase PostgreSQL

🔥 Why it matters:
MEIs are the backbone of Brazil's economy, but they're invisible to traditional finance companies. This meets them where they already are — on WhatsApp — and speaks their language.

📈 Current Status:
MVP ready. Starting closed beta with 50 real MEIs to validate retention and willingness to pay.

Beyond my three main products, I've built additional tools to sharpen my technical skills:

• VibeCoding — AI-powered development terminal (TypeScript + Claude API)
• Order Management API — Enterprise e-commerce system (.NET 8 + Microservices)
• Integration Gateway — API connector for distributed systems (C# + REST)
• Notification Engine — Multi-channel notification system (C# + Message Queues)

Full Stack Developer @ Despachante Marcelino Ltda
January 2024 - Present

• Building scalable web applications with React, Node.js, C#, and Python
• Implementing data-driven solutions with focus on user experience and business impact
• Working with modern software architecture, APIs, and cloud infrastructure

Administrative Assistant @ Casas da Água
January 2023 - December 2024

• Managed operations and customer support for retail business
• This experience taught me the operational side of business — a perspective most developers never get

Languages & Frameworks:

Databases & Infrastructure:

Web3 & APIs:

• 📚 Algorithms and Data Structures — UC San Diego (edX)
• 🧮 Essential Math for AI — Columbia University (edX)
• 💻 Programming & Data Structures — Columbia University (edX)
• 🏆 CS50: Introduction to Computer Science — Harvard University

Most developers build features. I build businesses.

Here's what sets me apart:

✅ I think like a founder, not just a developer
I don't ask "Can I build this?" — I ask "Should I build this? Who needs it? What's the market? How do I monetize it?"

✅ I ship MVPs, not perfect products
I launch fast, get feedback from real users, and iterate based on data — not assumptions.

✅ I understand both sides: tech AND business
Working in retail (Casas da Água) taught me how real businesses operate — cash flow, margins, customer behavior. This makes me a better builder.

✅ I focus on underserved markets
My projects target users traditional tech ignores: freelancers struggling with finances, startups locked out of Web3, people who can't afford therapists.

My philosophy:
Technology is a tool, not the goal. The goal is to create value for real people solving real problems they actually have.

I'm actively seeking opportunities to:

• Join a startup or accelerator where I can combine technical execution with business strategy
• Collaborate with founders and entrepreneurs who are building products that matter
• Learn from experienced product leaders and business strategists
• Scale one of my own projects into a real business

I'm not looking for a "just code" job. I want to build products, understand users, test hypotheses, and create impact.

I'm always open to discussing new projects, collaboration opportunities, or just exchanging ideas about technology, entrepreneurship, and product building.
