Services

I take a small number of consulting engagements per year, typically in the 40-120 hour range.

What I do well

• Yocto / OpenEmbedded BSP work. Meta-layer development, upgrades across LTS versions, custom image recipes, OTA via SWUpdate, bitbake deep-dive debugging.
• Kernel bring-up and BSP integration - mainline kernel patches, U-Boot, device tree, early boot, SPI/NAND/NOR/eMMC boot chains. Whatever silicon the project needs.
• Real-time Linux (PREEMPT-RT, Xenomai) for audio/industrial use cases where latency matters.
• Zephyr RTOS on constrained MCUs for sensor/control nodes.

What I don’t do

• Web frontends, mobile apps, ML pipelines - not my lane. I’ll refer you to someone who owns those.
• Pure “fix this line of code” jobs. I work on systems, not snippets.

How engagements work

1. Scoping call (30 min, free). We talk about what you’re building, what’s blocking you, what success looks like.
2. Short written proposal - scope, deliverables, milestones, timeline, total cost.
3. Work in two-week sprints with an async Loom / written update at the end of each. You can cancel after any sprint.
4. Final handover - all code in a branch you control, with a written summary of decisions and trade-offs for the next person.
