ESP32 firmware for keyboards and macropads with displays, with direct ownership of architecture, stability, and product continuity.

• Took ownership of Creator Micro 2, XYZ Work Board r2, Knob1, and Nomad [E] 2, becoming a technical point of reference for firmware continuity across the ESP32 product line.
• Built the XYZ Work Board r2 firmware from scratch starting from the PCB, turning hardware schematics, product requirements, and production constraints into a complete, verifiable firmware base.
• Drove the Creator Micro 2 and Knob1 firmware to completion and now maintain them with fixes, optimizations, and new features.
• Building the Nomad [E] 2 firmware and LVGL interface on its new hardware platform, also shaping the product UX and improving the UI to make interactions clearer and more coherent.
• Rewrote shared libraries for USB/BLE communications, RPC synchronization with Input, and power and charging management, removing fragile behavior and recurring issues.
• Translate PCB documentation, datasheets, and product requirements into verifiable firmware, hardware drivers, and HMI features, bringing order where hardware and product constraints meet.

Tractor cabin and cluster software, giving structure to machine data and making HMI components easier to integrate and validate.

• Consulting for SDF (SAME Deutz-Fahr) through Re:Lab, delivering hands-on contributions to tractor cabin software and onboard displays with the R&D team.
• Shaped the machine-data flow by separating communication, interpretation, validation, and application state, making the system easier to reason about and more robust.
• Introduced a Qt-integrated hardware-abstraction library that aligns reads, writes, and events with the application model, simplifying integration work.
• Created cluster pages and reusable QML components for indicators, controls, alarms, and popups, reducing duplication and visual inconsistencies.
• Drive latency improvements, regression fixes, and validation on the reference display, improving the perceived quality of the interface.

A collection of independent C++23 libraries created to turn experimental code into reusable, maintainable components.

• Set up a component architecture in which each module can be integrated, tested, and distributed independently, improving reuse and isolation.
• Building utility, container, time, and random modules following standard-library conventions, making the APIs predictable.
• Made the project verifiable with Doctest, CMake presets, AddressSanitizer, and UndefinedBehaviorSanitizer, increasing reliability and maintainability.
• Bringing ideas developed in Enne 2D into a simpler, more modular, and maintainable foundation, avoiding unnecessary complexity from the original project.

Native Android app for recording, synchronizing, and analyzing outdoor activities, built as a complete mobile product exercise.

• Conceived, designed, and developed the complete app with MVVM, clean architecture, and Jetpack Compose, creating a structured foundation that was easier to evolve.
• Integrated Google Maps, location services, and Firebase for authentication, synchronization, backend functions, and cloud storage, making the app usable end-to-end.
• Defined and documented user flows, system architecture, data movement, and module responsibilities, giving the project a clear technical direction.
• Optimized GPS tracking to balance accuracy, background continuity, and battery consumption, improving the real-world user experience.
