Outside of work, I have always been interested in building and creating; during my bachelor's, I tinkered with Adobe Photoshop, Illustrator and InDesign to help my volunteering projects (e.g., FEP Finance Club). Now, I use AI tools to build apps and websites.
iOS app · Personal finance
An iOS app that tells you what a salary in Portugal actually means: what lands in your account, what it costs your employer, where it sits against everyone else, and whether your payslip adds up
Built for the App Store, not yet submitted
0
servers, accounts or analytics
3
fiscal regions, each with its own tax tables
10
checks on every payslip, run on the phone
27
EU countries to compare against
01
Understand taxes
Every step from what your employer pays to what reaches you, each with its rate, then the annual settlement
02
Compare in Portugal
Your national percentile, and cohorts by sector, tenure, age, education and region
03
District map
What your sector pays, district by district
04
Compare in Europe
Where the same pay would sit across the 27 EU countries
05
Check payslip
Reads a PDF or photo on the device, checks ten things, and says which ones it could not check and why
06
Growth simulator
Your pay over 5, 10 or 20 years, staying put against changing employer
Other tools
Put a job offer next to your current job (monthly pay, tax, percentile, and what staying would pay), or try another salary without changing yours
Privacy is the product
The app has no networking code at all, so nothing you type can leave the phone, and its App Store label can say Data Not Collected without qualification. A payslip is read in memory and never written to disk.
Home is the whole app
One screen with your net figure and a row for each feature, and no tab bar. A one-time screen explaining the features was removed, because a Home that lists every feature does that job every time.
Say what the data cannot do
Every figure comes from a published, openly licensed source, and the app says on screen where the data runs out, for example that a sector is not a job title.
3
published datasets
Published data
Quadros de Pessoal 2024 (GEP-MTSSS), INE 2022 and Eurostat's Structure of Earnings Survey 2022, all openly licensed and bundled in the app
2026
tax rules
A real tax engine
Income tax and Social Security for all three fiscal regions, mainland Portugal, the Azores and Madeira, each with its own tables
142,272
job offers swept
Checked, not assumed
Verification tools sweep 142,272 job offers and 255,657 salaries for rules that must always hold, and check the tax tables against the official workbooks
Both built almost entirely with AI, using Lovable, and written in European Portuguese.
Website · Restaurant
My grandparents' restaurant in Santo Tirso, open since 1985, where D. Fernanda has cooked for more than thirty years. The page says what kind of place it is, shows the food, and keeps the phone one tap away, because the phone is how the restaurant takes bookings and shares the dish of the day.
Website · Interior decoration
My mother's interior decoration business, which she has run for more than twenty years. She works by appointment, so the site shows finished projects, introduces her, and makes it easy to book a visit by phone, WhatsApp or a short form.
