Learning Platform
We developed this project based on the client's specific needs, creating a complete and fully customized solution.
WebsitesConsulting Website
Trilingual digital platform for an international consultant, with a Sanity CMS–managed blog, animated hero and audience-segmented sections — an immersive experience with GSAP and particles.
WebsitesWebsite & Gift Cards
Brand website with gift-card e-commerce and a Beauty Bank (prepaid credit with tiered bonuses): Square and Stripe payments, an admin panel where the owner deducts services from the credit and tracks each client's balance and the overall total, photo gallery and QR codes — multilingual, with analytics.
WebsitesSite + Client CMS
Conversion site for a Kundalini activation specialist — gallery, videos, testimonials, FAQ and events. It ships with a custom CMS panel where the client updates photos, videos, testimonials, sessions, locations and text herself, with no developer needed. GSAP animations and responsive design.
SystemsCRM & Sales Platform
A complete sales CRM: lead, contact and deal management on a kanban pipeline, cadences and activities, email (with warming) and WhatsApp campaigns, GoTo telephony with transcription, AI-agent call and meeting analysis, automations and proposals — on an enterprise architecture.
Multi-agent System
A multi-agent AI system orchestrated with LangGraph: a router classifies intent and dispatches to specialized agents (CRM and finances) that act by connecting to the platform services. Powered by OpenAI and Anthropic models, exposed as a FastAPI service.
SystemsFitness Assessment App
Fitness assessment app for KONNEN: student registration with photo, performance tests (Cooper), heart-rate zones, VO₂max, BMI, evolution history with charts, and PDF report generation/sharing via WhatsApp and email — with password-protected access.
SystemsCalendar & Habits
A productivity app: calendar with recurring events, categories and labels, habit and weekly/monthly goal tracking, reminders and a dashboard — with Google Calendar sync. NestJS backend (Prisma/PostgreSQL) and Next.js frontend.
WebsitesWebsite & Proposals
Salto's multilingual website with protected sales decks (automation, websites, Google Business and service orders), briefing and service-order forms that generate PDFs and trigger automatic emails — GSAP animations, smooth scroll (Lenis) and event tracking.
SystemsProject Management
A Linear/Jira-style project management tool: workspaces, projects, issues, milestones, labels and features, with draggable kanban boards, time tracking, a dashboard, a command palette and authentication.
E-commerceOnline Store
A complete online store: catalog with variants (colors, sizes, brands and categories), persistent cart, MercadoPago-integrated checkout, shipping calculation, order management, an admin panel and accounts with email verification.
SystemsIncome-Tax Review (Desktop)
A desktop app (Tauri + Rust + React) for reviewing IRPF (Brazilian income-tax) returns: it imports and parses .DEC declaration files from Receita Federal, extracts data per taxpayer (CPF) and tax year (taxable, exempt and exclusively-taxed income) and organizes it locally in SQLite — with device-bound licensing (JWT) and a NestJS licensing backend.
WebsitesBeauty Salon Website
Single-page marketing website for Salão Loha (beauty & aesthetics in Osasco, Brazil): services, portfolio with lightbox, animated calendar, location and contact — Lottie/AOS animations and continuous deploy on Vercel.
Finance & Investments
A complete personal finance and investments system: accounts, transactions, categories, cost centers, budgets and goals, recurring entries and invoices, contributions, a crypto portfolio and market data (B3, Yahoo Finance, Binance) — including the Magic Formula stock screener.
