Lead Distributed Systems Architect & Enterprise ERP Engineer
Founder & Principal Architect at CODCrafters · Remote Worldwide

I design enterprise ERP systems, transaction backends, and offline-first mobile products. Over the past 6 years, I have delivered 91+ Odoo builds and 185+ total projects across Europe, the Middle East, and North America, reducing query response times by over 60% on multi-million row PostgreSQL databases.

• Enterprise ERP & Database Engines: Odoo 15 to 19, Python ORM, PostgreSQL query profiling, PgBouncer pooling, OWL reactive components, and zero-bloat modular architecture.
• Cryptographic Compliance: ZATCA Phase 2 E-Invoicing engine for Saudi Arabia and GCC, implementing ECDSA secp256k1 signing, SHA-256 UBL 2.1 XML hashing, QR code TLV digests, and automated clearance API handshakes.
• Distributed Product Engineering: Offline-first mobile systems on Flutter (Riverpod, Hive, SQLite) syncing with Next.js web applications and REST APIs.
• Lightweight DevOps: Self-hosted developer infrastructure on Linux, Docker, Nginx, and cloud clusters.

• Context: European distributor managing multi-currency parts catalogues, workshop orders, dynamic pricing, and EU VAT rules across split processes.
• Architecture: Odoo 17/18 Enterprise with PostgreSQL and OWL. Designed 15+ custom modules for real-time carrier APIs and optimized ORM query paths.
• Result: Cut core report generation latency by 60%, delivering sub-second response times on heavy concurrent inventory lookups. Automotive case study

• Context: Multi-department hospital running clinical records, billing, pharmacy stock, and insurance claims in disconnected tools.
• Architecture: Centralized Odoo HMS covering patient journeys, lab diagnostic workflows, pharmacy inventory, and automated billing.
• Result: Unified administrative and clinical operations into one database of record with role-based access control. Healthcare case study

• Context: Saudi enterprise requiring automated, tamper-proof electronic invoice clearance under ZATCA Phase 2 mandate.
• Architecture: Native Python and Odoo cryptographic engine generating canonical XML UBL 2.1, ECDSA digital signatures, cryptographic invoice hashing, and TLV Base64 QR encoding.
• Result: 100% compliant real-time API clearance with ZATCA Fatoora portal without third-party recurring SaaS fees.

Freelancers and agencies often juggle separate tools for CRM, tasks, timesheets, and invoicing. CLIVORA combines these into one synchronized workspace on Web and Android.

• Role: Founder and Principal Architect; designed full backend, database schemas, and mobile sync engine.
• Architecture: Flutter mobile client with offline-first local storage (Hive + SQLite) syncing with Next.js web console and REST endpoints.
• Availability: Live at clivora.io and published on Google Play.
