+# Mek-Tech Consultancy Framework — Architectuur
+
+## Overzicht
+
+Mek-Tech AI Consultancy Framework is een all-in-one consultancy CRM- en
+managementplatform. Het biedt clientbeheer, trajecten (engagements),
+facturatie, AI-gedreven advies, e-mailintegratie, backup/restore,
+dashboarding en rapportage. Drie Python-microservices verzorgen
+aanvullende functionaliteit: een visuele rack-editor, leadgeneratie
+via scraping, en datakwaliteitscontroles.
+
+## Tech Stack
+
+| Laag | Technologie |
+|------|-------------|
+| **Backend** | Node.js 18 + Express 4 |
+| **Database** | SQLite (via better-sqlite3) |
+| **Templating** | EJS — server-side rendered views |
+| **Auth** | bcryptjs + express-session |
+| **Microservices** | Python 3 + Flask (3 stuks) |
+| **Container** | Docker + docker-compose |
+| **Email** | IMAP (inbound) + Nodemailer (outbound) |

+Browser → Express (server.js)
+            ├── routes/ (auth check, params)
+            ├── lib/ (business logic, DB queries)
+            ├── data/ (SQLite reads/writes)
+            └── views/ (EJS render → HTML response)
+```
+
+- Alle routes doorlopen `server.js` voor sessie- en middleware setup
+- Business logic zit in `lib/`, niet in routes
+- Templates in `views/` worden server-side gerenderd
+- Python microservices worden aangeroepen via HTTP van de Node.js app
+
+## Microservices
+
+| Service | Poort | Map | Functie |
+|---------|-------|-----|---------|
+| **Python Designer** | 3001 | `python-editor/` | Visuele rack diagram editor — HTML/CSS designer-tool |
+| **Python Leadgen** | 3003 | `python-leadgen/` | Leadgeneratie: scrapet websites, extraheert contactgegevens, slaat op in DB |
+| **Python Quality** | 3002 | `python-quality/` | Data quality checks: valideert datasets, genereert kwaliteitsrapporten |
+
+Elke microservice heeft een eigen Dockerfile en draait als los Flask-appje.
+
+## Deployment
+
+### Docker Compose (5 services)
+
+```yaml
+services:
+  consulting:       # Node.js :3000 (hoofd-app)
+  python-designer:  # Flask :3001
+  python-quality:   # Flask :3002
+  python-leadgen:   # Flask :3003
+  showcase:         # apart project op :3010
+```
+
+Alle services draaien op `0.0.0.0` en zijn bereikbaar op het LAN.
+
+### Recovery (bij crash)
+
+1. `git clone` vanuit Gitea: `http://git.211:3000/mo/mek-tech-consulting.git`
+2. `.env` bestand aanmaken op basis van `homelab-configs/.env.example`
+3. `docker compose up -d` — alle containers starten
+4. SQLite DB (`data/consulting.db`) kan gerestored worden uit `data/backups/`
