What to use it for

Best fits for 2-hour packs

These packs are scoped — direct advisory time, not a full build. Best uses:

  • Architecture review — show me what you're building and I'll flag risks and shortcuts
  • Debugging deep-dive — bring the bug, share screen, ship the fix
  • Stack & component selection — second opinion on MCU choice, sensor choice, cloud platform
  • Code review — firmware, dashboards, or backend — pair-review with concrete suggestions
  • Hardware troubleshooting — wiring photos, scope traces, signal-integrity questions
  • Tutorial deep-dive — extended walkthrough of anything from the YouTube channel

FAQ

Quick answers

Can I split hours across multiple sessions?
Yes — any combination of 60-min, 90-min, or 30-min slots. The Calendly link supports all formats. Total hours just need to be used within 90 days.
Sync calls only, or can it be async?
Both. Send me code/schematics/questions over email or shared Notion, and I'll respond with a recorded video walkthrough or written feedback that counts against your hours. Useful for reviews that don't need real-time discussion.
What if I need more than 2 hours?
Two options: buy a larger pack for the better per-hour rate, or if the work becomes a full build, we can convert to a fixed-fee Build Sprint engagement. See our consulting page for details.
Do you sign NDAs?
Yes. Send me yours after checkout, or I can send a mutual NDA. I sign before any project details are shared.
Refund policy?
Full refund within 7 days of purchase if no sessions have been booked. After a session is booked or used, hours are non-refundable but transferable to another use case within the 90-day window.
Timezone?
US Central time. I work with clients globally — async option works for any timezone, and I'm flexible on live call timing.
