## 5. Private advisory practice (distinct from Resilience Guard)

Complementary **individual practice** for organizations needing **experienced technical leadership**, **pragmatic decision support**, and **precise delivery** for business-critical initiatives — under **separate agreements** from Resilience Guard client work.

**Services:**

- **Custom software development** — Made-to-order **web** and **mobile** applications (**iOS** and **Android**). Delivery commonly leans on **React** for web front ends and **React Native** for cross-platform mobile when a shared codebase and release rhythm fit the product; the stack is always mandate-specific.  
- **IT strategic consulting** — High-level advisory: technical leadership, infrastructure guidance, disciplined technology decisions.

**Positioning:** Resilience Guard = current **executive mandate** in resilience and continuity; the private practice converts that depth into **selected consulting** and **bespoke digital product** work for external clients.

**Selected work / portfolio:** Public apps appear in the home **Apps** section (`#selected-work`) when listed.

### Survival Plan (iOS) — Waiting for Review

- **Display name:** Survival Plan · Publisher: Theofanis Markou (selective product practice; separate from Resilience Guard).  
- **Positioning:** Offline-first organizational preparedness — plans, gear kits, expiry, ICE/Comms, Field Fix on-demand location snapshots. Not live navigation, not medical advice, not a substitute for 112 / emergency services. Languages in app: EN, EL, DE.  
- **Optional Pro:** Survival Plan Pro via Apple IAP (monthly/yearly); RevenueCat entitlement.  
- **URLs:** https://www.theofanismarkou.com/survival-plan · https://www.theofanismarkou.com/de/survival-plan · privacy `/survival-plan/privacy` · terms `/survival-plan/terms`
