Learning Platform
We developed this project based on the client's specific needs, creating a complete and fully customized solution.
WebsitesConsulting Website
A trilingual site for an international consultant: three languages with their own addresses, a separate path per audience, and a blog she publishes herself without calling a developer.
WebsitesWebsite & Gift Cards
A salon site that sells digital gift cards and prepaid credit with a bonus. The balance is always the credit minus what was used, so it cannot drift, and the owner deducts services and undoes mistakes from her own panel.
WebsitesSite + Client CMS
A conversion site for a Kundalini activation practitioner, with a panel she uses herself: gallery, video testimonials, sessions and venues all change without a developer, and photos taken on an iPhone are converted on upload.
SystemsCRM & Sales Platform
A sales system that takes a company from found on Google Maps to a signed recurring contract: pipeline, follow-up cadences, a self-service booking page, calls with recording and transcript, and campaigns in four languages.
Multi-agent System
One service running nine specialised assistants for the CRM and the finance system: a sentence on WhatsApp becomes a categorised expense, a sales call comes back reviewed, and a proposal is drafted and revised.
SystemsFitness Assessment App
An app a personal trainer uses to run fitness assessments and hand each client a branded PDF report on WhatsApp: Cooper test, VO₂ max two ways, BMI, heart-rate zones and progress charts.
SystemsCalendar & Habits
A deliberately small app that proves a system we build reads and writes the calendar a client already uses: two-way Google Calendar sync, recurring events with per-occurrence exceptions, and habit tracking.
WebsitesWebsite & Proposals
A four-language site for a sales consultancy, plus a password-protected area with five sales decks and service orders signed on screen, turned into a PDF and emailed, with an alert if the email does not arrive.
SystemsProject Management
The internal tool WB runs its own delivery on: every request becomes a typed issue with a priority, a live timer and a deadline counted only in working hours, plus a key-based API so other systems file issues themselves.
E-commerceOnline Store
A full online clothing store: filter by colour, size, brand and price, real freight quotes to the address, card and Pix payment, and a cart kept on the server so it follows the shopper between devices.
SystemsIncome-Tax Review (Desktop)
A desktop app for accounting offices that reads the raw income-tax declaration file, an undocumented fixed-width format, and lists the key figures per client. Published as a working core, not a finished product.
WebsitesBeauty Salon Website
A one-page site for a neighbourhood salon in Osasco, built to be found and to start a WhatsApp conversation: services, an 8-photo portfolio, map and social links, in plain HTML with no build step.
Finance & Investments
A system for personal and company money in one place: accounts with a month close, card invoice cycles, entries you can reverse, bank statement import with reconciliation, and a self-check that reports inconsistent state.
