Project description:
"I am looking for an Odoo specialist who can craft a production-ready, Android-based POS application that talks directly to Odoo Community Edition 19 and runs smoothly on both full-size and nano/small-form POS terminals used in our country.

Core scope
• Build a native (or very lean hybrid) Android app that pairs with Odoo 19 for catalogue, pricing, taxes, and real-time stock updates.
• Integrate card-present payments:
– Domestic debit/credit routed through the national switch (full EMV level-2 certification, online PIN, contact, and contactless).
– Visa/Mastercard transactions via EMV, NFC, and chip-and-PIN.
• Incorporate a customer loyalty layer—earned points, tiered rewards, and redemption synced back to Odoo contacts and sales.
• Two-way sync with our existing Odoo inventory module so that sales immediately decrement stock and any price or SKU change reflects on the terminal without manual refresh.
• Optional stretch goal: wallet acceptance (e.g., M-Pesa) if you have a proven SDK or API shortcut—quote that separately.

Technical highlights
• Must follow PCI-DSS best practices, store no PAN data, and support tokenisation from the acquiring host.
• Provide offline fallback with later batch settlement when connectivity resumes.
• Fast receipt printing, voids, refunds, tip-adjust, and end-of-day reconciliation.
• Clean, touch-optimised UI that scales from 4-inch to 7-inch screen sizes; dark-mode theme preferred.
• Clear separation between payment kernel, business logic, and front-end to ease future maintenance.

Deliverables
1. Architecture diagram and high-level design review.
2. First functional prototype running on the demo terminal we ship to you.
3. Complete source code with inline documentation plus install scripts/ADB packages.
4. Test plan and executed test cases covering EMV, NFC, loyalty flows, and inventory sync.
5. Deployment guide and hand-off workshop for our internal tech team.

Timeline
I would like the first clickable prototype within six weeks, and final acceptance (including certification support) no later than twelve weeks from kickoff.

If you have prior experience building EMV-compliant Odoo POS solutions or direct integrations with national card switches, please outline that history and mention the terminal models or SDKs you have used." (client-provided description)
