A done-for-you service for solo professionals, and tools I built for myself and gave away — the best proof of my work is using what I use.
The system that runs your practice between one client and the next.
Website, booking connected to Google Calendar, automatic emails, a client area, and a panel to run it all from your phone — built for solo professionals.
A multiplexed serial monitor for people who work with more than one device at a time.
Watch, send to, and manage several serial ports at once — in one browser tab, or as a native desktop app via the Web Serial API.
An htop-like memory monitor for ESP-IDF, over the serial console.
A real-time memory monitor: usage and fragmentation per heap region and per task, health checks, and a JSON Lines stream for host scripts.
idf.py add-dependency "pedroluisdionisiofraga/heaptop"HTTPS over-the-air firmware updates for ESP32, in a single struct.
Configure the firmware URL and an optional certificate, then run the update synchronously or in a background task that reboots into the new firmware on its own.
idf.py add-dependency "pedroluisdionisiofraga/ota-api"A command-line console for ESP32, without the ESP-IDF boilerplate.
Wraps ESP-IDF's console component and argtable3 into a simple API: define commands with declarative structs, with persistent history and automatic help.
idf.py add-dependency "pedroluisdionisiofraga/cli-api"A callback-based BLE GATT server, without the Bluedroid boilerplate.
Define services and characteristics with simple read/write handlers over ESP-IDF's Bluedroid stack — up to 8 services with 16 characteristics each.
idf.py add-dependency "pedroluisdionisiofraga/ble-gatt-server"These four tools came out of real projects. If what you need doesn't exist yet, that's what the conversation is for.
Describe the problem in one line. I reply within two business days with an initial diagnosis free, before any proposal.
