Embedded Firmware & IoT Systems Architect
I help teams turn prototype firmware into production-ready connected systems that survive real-world deployment.
Focused on OTA safety, telemetry reliability, wireless stability, diagnostics, battery optimization, and connected-device architecture for products that need to ship and keep working.

Overview
Consulting support for connected products that need to survive production.
Structured like a profile page, but written for engineering leaders and product teams who need stronger firmware execution, connected-system architecture, and lower field risk.
I help engineering teams turn prototype firmware into production-ready connected systems that survive real-world deployment. My work sits at the point where low-level firmware, device lifecycle strategy, and field reliability have to operate as one system instead of separate disciplines.
Over 13+ years, I have worked across embedded C/C++, RTOS platforms, wireless stacks, OTA workflows, telemetry systems, diagnostics, and recovery logic. The focus is not novelty for its own sake. It is getting connected products stable, observable, and supportable at production scale.
Clients typically bring me in when firmware architecture needs tightening, fleets need better diagnostics, OTA delivery needs to become safer, or a connected device program needs stronger technical leadership before field issues turn into business risk.
Fleet diagnostics & reliability
Telemetry, watchdog recovery, and observability that help teams debug live systems faster.
Architecture modernization
Clearer firmware boundaries, stronger integration patterns, and more maintainable device programs.
Experience
A consulting profile built from firmware depth, fleet reality, and connected-system accountability.
The format is intentionally more profile-oriented than resume-like: a compact view of the roles and operating contexts that shaped the consulting approach.

2011-2018
Role 03
Firmware Reliability & Scale Specialist
Fleet-scale IoT deployments
Built the low-level depth behind later architecture work: board bring-up, wireless integration, firmware debugging, power tuning, and failure analysis.
Bring-upWirelessPower TuningFailure Analysis
- Hardened device behavior around fault handling, reset recovery, and long-term maintainability.
- Improved battery and throughput tradeoffs under real deployment conditions.
- Created stronger debug signals for field teams and cross-functional engineering groups.
- Built the foundation for later work in OTA safety and cloud-connected system scale.
Impact
Featured results
Three consulting themes that show up repeatedly in production firmware programs.
Featured impact
Production OTA resilience
Built safer update behavior by focusing on rollback-aware delivery paths, recovery diagnostics, and release flows that remain supportable after devices leave the lab.
Outcome
More confident firmware rollout and lower operational risk during updates.
Featured impact
Power and performance tuning
Improved runtime efficiency by working through scheduling, peripheral behavior, telemetry cadence, and firmware hot paths without breaking reliability targets.
Outcome
Better battery life and responsiveness under production constraints.
Featured impact
Architecture modernization
Restructured firmware and connected-system boundaries so telemetry, OTA, diagnostics, and application logic became easier to maintain, validate, and scale.
Outcome
Cleaner technical ownership and faster iteration for growing device programs.
