I build real-world technology solutions connecting hardware, firmware, RF communication, IoT devices, Linux systems, backend integrations, automation tools and technical content.
I develop practical technology solutions that connect the physical world to software.
My work usually involves embedded systems, IoT devices, RF communication, hardware prototyping, Linux-based systems, APIs, dashboards, automation tools and product-oriented development.
I work with technologies such as C, C++, C#, Python, MicroPython, STM32, ESP32, Raspberry Pi, LoRa, LoRaWAN, LoRaMesh, RS485, Modbus, MQTT and Linux-based gateways.
My public GitHub repositories represent only the visible layer of my work. A significant part of what I build is developed in private repositories, client projects, company systems, commercial prototypes, internal tools and confidential engineering environments.
I like building systems that are not only interesting in theory, but useful in real environments.
Main areas:
- Embedded systems and firmware development
- IoT devices, gateways and telemetry
- RF communication, LoRa, LoRaWAN and LoRaMesh
- STM32, ESP32, Raspberry Pi and Linux
- Industrial communication, RS485, Modbus and MQTT
- Hardware debugging and field diagnostics
- Backend integrations for connected devices
- 3D printing and functional prototyping
- Technical content, documentation and open-source tools
Elcereza is my technology ecosystem focused on engineering, open-source experimentation, technical content and product development.
Through Elcereza, I work on projects involving embedded systems, IoT, RF communication, automation, hardware prototyping, software integrations and educational content.
The goal is to create practical engineering content, open-source tools and technology solutions that connect software, electronics, communication systems and real-world product development.

A significant part of my work is developed in private repositories or under client, product or company confidentiality.
For this reason, private repositories, client names, internal product names and sensitive technical details are not listed here.
These private projects usually involve:
- Custom embedded firmware
- IoT devices and gateways
- Industrial monitoring systems
- RF and telemetry experiments
- Hardware validation and diagnostics
- Field-oriented product development
- Web systems connected to physical devices
- Internal automation and technical tools
- Product prototypes and commercial engineering projects
The public repositories above represent the same technical areas I work with, without exposing confidential information.
Idea / problem ↓ Hardware architecture ↓ Prototype ↓ Firmware ↓ Communication protocol ↓ Gateway / backend / API ↓ Dashboard / integration ↓ Testing, debugging and product iteration
I enjoy working on projects where hardware and software need to work reliably outside the lab.
I am especially interested in projects involving:
- Embedded products
- IoT platforms
- RF communication
- Long-range telemetry
- Industrial automation
- Hardware/software integration
- Open-source tools for hardware developers
- Technical content for real engineering problems
- Product development from prototype to field testing
