## Pricing

Formula: price(h) = 120 × h^0.667 — sublinear, effective rate drops with volume.
$120 first hour → ~$35/h at 40h. Post-delivery payment, no deposits. USDT −15%.

Service tiers (multiplicative):
- Remote ×1.0 — I solve it, you get results
- Live ×1.5 — We solve it together, real-time
- Advisory ×1.75 — I teach, you learn, we validate
- Emergency ×2.0 — Everything stops, any hour, immediate

Billing cycles auto-close: idle gap > h×2 days (cap 14). Warranty: h×1.5 months (cap 36).
0.5h granularity. First 30 minutes free.

## AI Fluency

- Level 4 AI Architect: context systems, reusable frameworks, multi-model orchestration
- Context engineering: structured research briefs, business DNA compression, grounding infrastructure
- RouterOS reference dataset for AI hallucination prevention
- Token optimization: 60-80% non-code token reduction (measured)
- New service category: AI rescue (fixing AI-hallucinated network configs)
- Philosophy: "Context is capital. AI accelerates the work; the expert owns the outcome."

## Security Posture

- 3-tier CA hierarchy, hardware-backed — ca.tarikin.com
- GPG: A829 222C ADA3 8E9B E140 EA9C 11AE 5088 0470 27C4 (keys.openpgp.org)
- DNSSEC: active on tarikin.com
- All git commits cryptographically signed (hardware-backed)
- Air-gapped key ceremony, offline master keys in bank deposit
- Physical touch required per cryptographic operation
- Website: zero external resources, zero cookies, zero tracking, Mozilla Observatory A+

## Constraints

- Solo practitioner — 1-2 major concurrent projects max
- MikroTik only — not Cisco/Juniper/Arista
- Remote-only — "customer does physical, engineer does logical"
- GMT+7 timezone (10:00-20:00), 1-2 days advance booking
- Conservative marketing — discovery is #1 bottleneck, peer referral primary channel
