Firmware, hardware integration, and control-minded engineering
Joao Pedro Miranda Marques
Embedded Systems Engineer building real-world devices from firmware and low-level interfaces through physical prototyping, validation, and deployment.
My background connects product-minded prototyping, automotive ECU work, and closed-loop automation. I like projects where software has to respect signals, timing, hardware limits, and the reality of field use.

Based in Budapest
Open to embedded systems, automotive software, and control automation roles across Europe.
Embedded product work
Hands-on device work with ESP32 platforms, BLE, Wi-Fi, camera modules, sensors, actuators, and enclosure-aware iteration.
Automation and control
Control-minded software for experiments and physical systems, including Python-based acquisition, calibration, and repeatable tests.
What I work on
Three lanes that fit together cleanly.
01
Embedded devices
Firmware architecture, hardware integration, low-level interfaces, debugging, and practical validation in the loop.
02
Automotive software
ECU middleware and basic software work shaped by reliability, traceability, and cross-team integration constraints.
03
Control systems
Closed-loop automation and data handling for noisy physical processes where calibration and repeatability matter.
Selected projects
Card-based case studies with real build photos.
Each project combines actual hardware visuals, concise technical context, and a direct link when the work is open source.
Project Octopus
1/4
A compact ESP32-based room camera project that combines camera bring-up, enclosure design, PIR-triggered wake flow, Wi-Fi, and Telegram delivery. It started as a battery-focused concept and evolved into a more practical wired direction after real power-budget testing.
- Implemented a working prototype that booted, monitored battery voltage, initialized the camera, joined Wi-Fi, and uploaded photos to Telegram.
- Iterated custom 3D enclosure concepts from CAD through printed fit-check prototypes.
- Used real battery-life testing to pivot the architecture toward a more dependable product direction.

DIY DJ Controller
1/4
A custom USB-MIDI DJ controller for Mixxx, built around a hand-assembled prototype with multiplexed inputs, rotary encoders, and a 3D-printed enclosure direction. The focus was human-interface firmware and real usability, not just board bring-up.
- Reads digital inputs through an I2C GPIO expander and analog controls through a 74HC4067 multiplexer.
- Handles rotary encoders for jog-wheel and browser interaction while sending USB-MIDI notes and CC messages.
- Validated the prototype as a usable controller and documented limitations for the next hardware revision.

Smart Digital Hydrometer
1/4
An ESP32-based digital hydrometer subsystem developed for concrete-truck R&D, measuring and controlling water flow, communicating over BLE, and supporting calibration plus field validation in harsh vehicle environments.
- Built a dual-core FreeRTOS firmware architecture with finite-state-machine control and runtime resource analysis.
- Implemented calibration and software compensation to maintain dosing accuracy under component wear.
- Took the subsystem through PCB revisions and truck-mounted field trials inside an R&D engineering team.

Built to introduce you cleanly, and ready to deploy as a static Next.js site.
The current setup is intentionally static-export friendly, so it stays simple to host and cheap to run. If you want, the next iteration can add a blog, project detail pages, or CMS-backed editing without changing the visual language.
