How Engagements Work

Most engagements start with a free 30-minute discovery call. From there, I typically work in one of three modes:

🗓️ Fractional (Ongoing)

2–3 days/week, 3–6 month engagement.

Best for: startups and scale-ups that need a senior CTO without a full-time hire.

Deliverables: weekly syncs, architecture decisions, team leadership, board-level reporting.

🎯 Project-Based

Fixed scope, fixed timeline.

Best for: AI product builds, cloud migrations, platform audits, or compliance sprints.

Deliverables: defined at scoping, delivered with an evidence pack.

🔍 Advisory (Light-touch)

4–8 hours/month.

Best for: founders or CTOs who need a senior sounding board and second opinion.

Deliverables: async reviews, monthly strategy call, written recommendations.

All engagements start with a no-obligation discovery call. Pricing is scoped to the engagement — reach out to discuss your situation.
