Expertise in launching early stage startups.

Software engineer with 8+ years building and maintaining production C/C++ and Qt/QML systems on embedded Linux, most recently on agricultural guidance and control systems. While embedded and Qt work is my deepest specialty, my background in computer engineering fundamentals and years of working across complex, long-lived codebases means I'm comfortable taking on work outside that core when the problem calls for it. Core specialties: Embedded Linux application development in C/C++ Qt/QML development for HMI and cross-platform desktop applications (formal Qt/QML training completed) Python for tooling, automation, scripting, and data processing Cross-component debugging and production defect resolution on long-lived codebases Tracing system behavior end-to-end across legacy and active components Code review, design input, and release readiness work Also open to: General C/C++ and Python work outside the embedded space Legacy codebase maintenance, modernization, and Qt version migration Technical consulting, code review, and architecture discussions Adjacent problems where strong debugging instincts and systems-level thinking matter more than prior exposure to a specific stack AI-assisted engineering: I work daily with current AI coding tools (Claude Code, Codex CLI, Gemini CLI) and keep up with how they're evolving. My approach is to use them to increase throughput without compromising quality - maintaining repository-level instruction files, reusable prompts, and structured context so the tools produce consistent output; reviewing what they generate rather than accepting it blindly; and recognizing their failure modes (hallucinated APIs, missing context, overreach) before those failures ship. The result is faster work on large or unfamiliar codebases without the quality regression that comes from treating AI output as finished code. How I work: Full Agile/Scrum participation (sprint planning, reviews, retrospectives, occasional facilitation) Experienced in distributed teams with coordination across time zones Clear communication with both technical and non-technical stakeholders Good fit for: Embedded C++ projects on Linux Qt/QML HMI development for industrial, agricultural, or instrumentation equipment Cross-platform C++/Qt desktop applications (Qt 5 or Qt 6) Python scripting, tooling, and automation work Legacy C/C++ codebase maintenance or modernization Production debugging on systems where correctness and stability matter

I'm Michael- I build the missing AI and automation layer that makes Microsoft stacks earn their keep. → Built an agentic carrier bill reconciliation system for a $60M distributor. Ingested invoices in any format, reconciled against shipment data, flagged duplicates and unauthorized accessorials, output AP-ready files automatically. Recovered $180k/year in overcharges with a 20%+ lift in disputed charge win rate. → Engineered a native NetSuite substitution engine powered by a custom ML model. Surfaced optimal product recommendations automatically, reduced bad-sub complaints, and grew sales order conversion by giving reps lower landed cost alternatives in real time. → Built a partitioned context agent for inside sales and customer service that quoted orders using historical order data, carrier pricing, inventory, and full customer interaction history. Reps quoted faster, smarter, and won more. → Automated document and invoice processing for an Azure-based SMB. Cut processing time from 3 days to under 2 hours, eliminated $50k/year in manual labor. Before going independent I built full stack and ML systems for Fortune 500 companies, led teams through full delivery cycles, and was an early engineer at a defense AI startup competing with Lockheed Martin and Collins Aerospace. Six years shipping production systems in Python, Node.js, and Go. If you're running on Azure, M365, or a Microsoft-adjacent ERP and your team is still doing work a well-configured system should handle, that's exactly the problem I solve. Be well, Michael P.S. If you have no infrastructure at all right now, I can help there too! I have set up all the Microsoft pieces you would need for the capabilities listed above. Always happy to chat to learn more about what you need.
