Apps
Eleven tools, bots and experiments, from a weekly time tracker to small utilities I made because I needed them. Each entry keeps its current status and licence explicit.
Featured software
A weekly time tracker, an on-device computer-vision application and a self-hosted portfolio-analysis tool.
Time tracking · Free public beta
A focused weekly time and task tracker with goals, streaks, manual corrections, a live timer, reports, exports and team workspaces. The current launch has no billing, paywall or trial countdown.
Computer vision · Web / PWA / Android
Try four vector frame styles with real-time face tracking, smoothing, perspective response and face-aware temple-arm occlusion from one cross-platform codebase.
Portfolio analytics · Self-hosted
A browser-first portfolio workspace for XTB and future IBKR imports, allocation analysis, benchmarks, data-quality checks and FIRE-oriented exports.
Chatbots
Porto transport and U.Porto canteen information through familiar chat services.
Multiplatform chatbot · Porto transport
Check expected passages, inspect line stops and keep platform-specific favourites through Telegram, Discord or encrypted Matrix direct messages.
Telegram bot · U.Porto canteen menus
A quick way to check weekly canteen menus from Multirest. I built it because I wanted the menu without repeatedly opening the supplier website.
Browser tools
Portuguese tax preparation, interest comparisons and a hands-on way to learn binary representation.
Tax preparation · PT
Import exchange CSVs, reconstruct transaction history, build FIFO lots, review ambiguous events and export organised figures for Portuguese IRS preparation.
Calculator · PT / EN
Compare deposits and cash products with separate terms, crediting frequencies, periodic top-ups, tax assumptions and annualised net returns.
Interactive learning · Browser / ESP8266
Learn binary representation with six interactive switches, live sums and optional physical LED feedback through the original ESP8266 build.
Self-hosted and installable
A wallpaper-sharing service and a dependency-light GNU/Linux wallpaper utility.
Self-hosted wallpaper community
A deployable PHP gallery and API for a shared wallpaper pool, paired with an atomic GNU/Linux desktop client and systemd user timer.
Desktop utility · Command line
Download a Microsoft Spotlight landscape image, validate it and atomically update a configured wallpaper file using a small POSIX-shell command.
Experimental
Ideas that are still useful to inspect, but are not presented as finished products.
Experimental meal-planning prototype · PT
Generate a Portuguese-language monthly meal plan and shopping list from adult inputs, a small curated catalogue and Open Food Facts product data.
