Custom Software Development

Integrated Electronic Development Services

A comprehensive, tailored approach to transform your idea into a successful product. From single-component design to full-system engineering, I offer flexible support for every stage of your project.

1. Product Engineering and Hardware Design

The success of an electronic product begins with meticulous design. This phase is crucial for defining the device's foundation, ensuring it is high-performing, reliable, and sustainably manufacturable.

Feasibility Analysis and Requirement Definition: I work with you to turn an initial idea into a set of concrete technical requirements. Together, we analyze goals, cost targets, and technological challenges to define the best design strategy.
Schematic Design: I create complete electrical schematics, carefully selecting every component (microcontrollers, sensors, power components, connectivity modules) to optimize performance and ensure long-term availability, preventing future obsolescence.
Circuit Simulation and Analysis: Even before creating a physical prototype, I run simulations to verify the circuit's behavior, validating design choices and preventing costly errors in later stages.
Design for Manufacturing (DFM/DFA): I design with industrial production in mind. I optimize the design to simplify assembly (Design for Assembly) and fabrication (Design for Manufacturing) processes, reducing production costs and defect rates.

2. Firmware and Embedded Software Development

Firmware is the soul of the product: the code that executes instructions, manages interactions, and makes the device "smart." I develop efficient and scalable embedded software.

Microcontroller (MCU) Development: I have extensive experience with the main 8, 16, and 32-bit microcontroller families (such as STM32, ESP32, Microchip/Atmel, NXP). I write optimized C/C++ code to fully leverage the hardware's capabilities.
Drivers and Peripherals: I develop low-level drivers to manage all types of peripherals: sensors (accelerometers, gyroscopes, environmental sensors), memories, displays, actuators, and more.
Communication Protocols: I implement standard and custom communication protocols, both wired (I2C, SPI, UART, CAN, Ethernet) and wireless (Bluetooth/BLE, Wi-Fi, LoRa, Sub-GHz RF), to ensure your device can communicate effectively with the outside world.
Control Logic and Algorithm Development: From managing signal processing algorithms (DSP) to creating complex state machines for device control, I develop the application logic that brings the required functionalities to life.

3. From PCB Layout to a Working Prototype

The transition from a digital design to a physical object is a critical step. I manage this phase with the utmost precision, using industry-leading tools.

PCB Layout with Altium Designer: I create printed circuit board layouts, from simple double-sided boards to complex multi-layer designs. I pay close attention to Signal Integrity, Power Integrity, and impedance control—fundamental aspects for high-frequency or high-density devices.
Electromagnetic Compatibility (EMC/EMI): I design PCBs following best practices to minimize electromagnetic emissions and increase immunity to interference, facilitating the final product's certification process (e.g., CE marking).
Prototype Management: I interface directly with PCB manufacturers and assembly services (PCBA) to create the first prototypes. I manage component sourcing (BOM management) and oversee the assembly to provide you with a high-quality, functional prototype in the shortest possible time.

4. Upgrades, Optimization, and Problem Solving

I also offer support for existing products and projects to improve them, solve problems, or adapt them to new market demands.

Redesign and Technological Upgrades: Does your product use obsolete or expensive components? I perform a full or partial redesign of the board to update it with more modern, efficient, and cost-effective technologies.
THT to SMD Conversion and Modernization: I specialize in re-engineering legacy boards based on Through-Hole Technology (THT). I convert your legacy circuits to modern Surface-Mount Device (SMD) technology to dramatically reduce size, automate and cut down assembly costs, and improve overall electrical performance.
Failure Analysis and Debugging: Through methodical analysis and the use of lab equipment, I identify the root causes of hardware and firmware malfunctions, proposing effective and permanent solutions.
Reverse Engineering: If you no longer have the documentation for an old project, I can perform reverse engineering to reconstruct schematics and layouts, allowing you to perform maintenance or upgrades.
Cost Optimization: I analyze your product's Bill of Materials (BOM) and design to identify opportunities for cost reduction, both at the component and production process levels.

5. Functional Safety and Reliability Analysis (IEC 61508)

In safety-critical applications, safety is not an option—it is a fundamental requirement. I provide expert skills for designing electronic systems that must comply with rigorous functional safety standards, with a focus on IEC 61508.

FMEDA (Failure Modes, Effects, and Diagnostic Analysis): I perform a systematic, quantitative analysis at the component level. For each element in the circuit, I identify potential failure modes, their effects on the system, their probability of occurrence, and the effectiveness of diagnostics in detecting them.
Calculation of Safety Metrics: Based on the FMEDA, I calculate the key metrics required by the standard, including PFH (Probability of Failure per Hour), SFF (Safe Failure Fraction), and DC (Diagnostic Coverage), to determine the achievable SIL of the architecture.
Safety-Oriented Hardware Architecture Design: This is not just analysis, but also design. I develop hardware architectures (e.g., with redundant channels, fail-safe mechanisms, self-diagnostic circuits) conceived from the ground up to meet the requirements of a target Safety Integrity Level (SIL 1, 2, or 3).
Documentation for Certification: I produce the detailed technical documentation, including the FMEDA report, required to support the certification process of your final product with the relevant authorities.
