Software & Embedded Systems Consulting

Expert consulting in software integration, unit testing, embedded systems, and educational technology

I solve technical challenges that require both depth and breadth - from firmware running on ocean wave buoys to enterprise-scale educational platforms. As an independent consultant, I bring focused expertise without the overhead of large firms.

Systems Integration & Architecture

Turn disparate systems into cohesive solutions

• API integrations and data pipeline development
• Legacy system modernization and interfacing
• Build system design and CI/CD implementation
• Testing automation and validation frameworks
• Security hardening and reliability engineering
• Connecting hardware including factory and farm automation

Perfect for: Engineering teams needing quick automation scripts, test harnesses, or full-scale system integrations.

Embedded Systems Development

From prototype to production-ready firmware

• Platforms: AVR, ESP32, STM32, Raspberry Pi, Embedded Linux
• Real-time OS: FreeRTOS and bare-metal programming
• Protocols: I2C, SPI, UART, CAN, MQTT, BLE
• Communications: LoRa long-range radio, Iridium satellite modems
• Power optimization: Ultra-low power designs for battery-powered devices
• Applications: Remote IoT devices, sensor systems, data loggers, industrial controls

Recent example: Firmware development for ocean wave measurement buoys - reliable data collection in harsh marine environments with satellite connectivity and multi-year battery life.

Educational Software Systems

Two decades building learning platforms

• Learning management system architecture
• Assessment and analytics platforms
• Content delivery and student engagement tools
• Integration with institutional systems
• User Management
• Scalability for concurrent users

Technical Expertise

• Languages: C/C++, JavaScript, Python, Perl, Fortran, and much more
• Areas: Resolving operating system level dependency issues, Automating software installation/build process
• Tools: Make, Linux
• Services: Authentication, APIs, Binary data manipulation
• Electronics: Embedded CPUs, Display Panels, Power Management, Radio including LoRa
• Infrastructure: Version control (git), automated testing, continuous integration, monitoring
• Approach: Start simple, iterate fast, build for reliability, documenting along the way

How I Work

• Hourly consulting at $175/hour for remote work
• Project-based engagements for defined deliverables
• Part-time availability with flexible scheduling
• Estimates, not quotes - complex technical work requires flexibility

I believe in transparent communication and realistic timelines. You’ll get honest assessments of what’s possible and what it will take to get there.

Ideal Projects

• Quick wins: Automation scripts, test frameworks, or integration proof-of-concepts
• Embedded systems: Sensor devices, data loggers, or industrial controllers
• Major implementations: Educational platforms, system modernization, or enterprise integrations

Why Work With Me?

• Full-stack embedded to cloud: I understand the entire system, not just one layer
• Pragmatic solutions: The right tool for the job, not resume-driven development
• Network when needed: Access to trusted PCB design and hardware experts
• Remote-first: Efficient collaboration without geographical constraints

Examples and Success stories

• WII: Waves In Ice - Published in Nature sea ice wave detection systems.
• Profitool: Automation, unit testing and 64 bit conversion of legacy accounting/ERP system
• OSDC: Open Source Developers Conference founder

Let’s Talk

Have a system that needs connecting? Embedded device that needs programming? Remote monitoring? Data analysis and visualization? Educational platform that needs scaling? Legacy system that needs modernization? Unit testing, build systems and automation?
