Back-End Developer
Maurício Wander
Back-End Developer focused on building reliable APIs, automation, and scalable server-side systems.
About me
My interest in computers started with Minecraft Java servers, emulators, and Pokémon FireRed hacks. Programming turned that curiosity into a way to build useful things.
Today I focus on back-end development with Python, building practical systems that are reliable, maintainable, and easy to improve.
Projects
MiniTask
A portable Windows app that records and replays mouse and keyboard actions to automate repetitive tasks. Save recordings, adjust playback speed and repetitions, and control everything with global shortcuts. Built with C#, .NET, and WPF, it runs locally and offline without an installer. Currently in public beta.
Retail Intelligence
A reproducible Python and SQL pipeline that explores sales concentration, repeat purchases, and customer retention using public retail transactions. It builds a SQLite analytical warehouse and produces monthly metrics, cohort tables, a dashboard, and a findings report with proposed next steps.
Resizy
A Python command-line tool that resizes, converts, and compresses batches of images in one command. Parallel worker processes handle image processing while the terminal shows live progress. A dry-run mode lets you review planned changes before writing files.
