My Masters of Sciences in Mechatronics Engineering degree is just an academic achievement. My stronger suite is the development of high end science research equipment that require multi-disciplinary skills. During the past 10 years, I've developed some astonishing projects in a diverse field of engineering; from wordpress websites to high performance web servers for IoT networks, from purpose built embedded machine interfaces to picosecond resolution time converters on FPGA's, from rugged and high reliability mechanical weather samplers to robust and intelligent smartphone image processors, I have a lot of projects to boast on. I don't only love my profession, but I'm actually very good at it too.

Many hardware startups waste months and tens of thousands of dollars building the wrong prototype. I help founders define the right hardware architecture before building the prototype, so the first version of the product actually validates the idea. My work focuses on the early stages of hardware product development, where a few key technical decisions shape the entire project. Instead of jumping straight into PCB design, I help clarify the system architecture, identify technical risks, and define the fastest path toward a functional prototype. As a licensed Professional Engineer in Québec, Canada (OIQ), I specialize in turning early product ideas into clear technical plans and realistic prototype strategies. I often join projects at the stage where the idea is clear but the technical path is not. My role is to help teams answer critical questions such as: • What is the simplest prototype that validates the product idea • Which architecture decisions will scale to production • What technical risks should be addressed early • Which components and technologies are the right fit • What development roadmap makes the most sense Once the architecture is clear, I can support the development of functional prototypes including electronics, firmware, and mechanical integration. 🧠 TYPICAL STRATEGIC ENGAGEMENTS Prototype Architecture Review A deep technical review of a product concept or existing design to identify risks, validate architecture choices, and define the best technical direction. Clients typically leave with a clear architecture strategy and actionable recommendations. Prototype Roadmap Define the fastest and safest path from concept to working prototype. This includes system architecture, component selection strategy, and a realistic development roadmap. Technical Design Review Independent engineering feedback on an existing design before committing to development, manufacturing, or scaling. 🧭 HOW I USUALLY WORK Most projects start with a short architecture or prototype strategy engagement. This allows us to clarify: • system architecture • key components and technologies • technical risks • development roadmap Typical activities may include: • review of product concept, architecture and BOM • prototype architecture definition • identification of design and manufacturing risks • practical recommendations to simplify development • a clear next step roadmap This approach keeps projects efficient, predictable, and aligned with real world hardware constraints. 🔧 CORE EXPERTISE • hardware system architecture for embedded and IoT products • prototype strategy and rapid product validation • embedded systems and low power electronics • wireless systems including WiFi, BLE, Zigbee and LoRa • sensor systems and motor control architectures • system level integration across electronics, firmware and mechanics 🧪 PROTOTYPE DEVELOPMENT CAPABILITIES Once the architecture is defined, I can support the development of functional prototypes including: • electronic design and PCB development • embedded firmware development • sensor and wireless integration • mechanical prototyping with 3D modeling and printing My lab is equipped for rapid hardware development, allowing ideas to move quickly from concept to working hardware. 🚀 TYPICAL SITUATIONS WHERE I HELP • exploring a new hardware product idea • preparing the first functional prototype • evaluating or improving an existing architecture • reducing technical risk before major development investment • turning a proof of concept into a reliable prototype 🎯 FIT I work best with startups, innovators, and small product teams developing new hardware products. If you are exploring a product idea, preparing your first prototype, or trying to reduce technical risk before committing to development, I can help. If you are looking for open ended task execution or low level outsourcing, I may not be the right fit. 💬 LET’S TALK If you are working on a hardware product and want to move from idea to a realistic prototype strategy, I would be happy to discuss your project. Clear architecture decisions early in a project can save months of development and significant cost. Let’s build something real, testable, and engineered to succeed.

I am an Electronics Engineer specializing in embedded systems, custom hardware design, and automation. My background includes supervising high-stakes instrumentation and control commissioning in the oil and gas sector. I bring that same standard of industrial-grade reliability and strict project management to every freelance project I take on. Whether you need firmware written from scratch, a custom circuit designed, or a prototype brought to life, I can manage the entire development cycle to ensure your hardware works exactly as intended. Core Capabilities: Hardware Design: Digital and analog electronics, custom PCB design, and rapid prototyping. Firmware & Software: C, C++, and Python. Platforms & Microcontrollers: ESP32, STM32, Arduino, PIC-based boards, and others. IoT & Wireless: BG96, nRF9160, and others. SBCs: Raspberry Pi. I deliver clean, well-documented work and communicate clearly from concept to final delivery. Let's discuss your project requirements.

I build connected hardware products end-to-end — PCB through cloud through mobile app. Clients hire me when they've realized the hard part of a hardware product isn't any single layer — it's the integration. The firmware that talks to the sensor that talks to the cloud that trains the model that deploys back to the device that pushes to the mobile app. I've personally built and shipped every one of those layers, which means I debug at the seams where specialists get stuck. I do my best work in three domains: - Industrial and commercial IoT — factory automation, predictive maintenance, quality control, sensor networks, robotics, and high-reliability data acquisition. - Consumer products — smart home systems, connected gadgets, wearables, and companion mobile apps. Consumer hardware lives or dies on polish: enclosure fit, app UX, time-to-pairing. I design with that in mind from day one. - Medical devices — sensor-based monitoring, data acquisition, and connected health hardware. I build to documentation and traceability standards that support regulatory pathways, working alongside your QA/RA lead on the formal side. My stack covers the full product: - Electronics — custom PCB design in KiCad, in-house pick-and-place and debug bench, deep ESP32 experience across the peripheral stack (I2C, SPI, UART, CAN, RMT, ADC, PWM, touch, camera) plus BLE, Wi-Fi, LoRa, and cellular. - Mechanical — enclosures, mounts, and structural parts in FreeCAD, with in-house FDM and SLA 3D printing and laser cutting for rapid iteration. - Firmware — embedded C/C++ and ESP-IDF, real-time control, sensor fusion, OTA updates, robust field deployment. - Cloud on AWS — IoT Core, device fleets and provisioning, data pipelines, serverless backends, secure MQTT, time-series storage. - Machine learning — predictive maintenance, anomaly detection, computer vision for quality control and health monitoring. Training pipelines plus optimized deployment to edge or cloud. - Mobile apps — companion apps for device control, commissioning, monitoring, and end-user experience. - CI/CD and Linux infrastructure — full deployment stacks for firmware, cloud, and ML. What ships is what was tested. I default to KiCad, FreeCAD, Linux, and open standards. You own your files and can work with any vendor, any shop, any future engineer. No one holds your design hostage behind a license renewal. For industrial and medical products maintained for a decade or more, this isn't aesthetic — it's risk management. I'm a good fit if: - You need one person who can own the whole system - You have a stalled prototype with problems at the integration seams - You value traceable, vendor-independent deliverables I'm not the right fit if: - You need pure-software work with no hardware - You require a proprietary tool chain like Altium or SolidWorks as a hard constraint - You're shopping on price — I'm priced for full-stack ownership Send a short brief of what you're building and I'll tell you within a day whether it's a fit and roughly what the scope looks like.
