Solutions Architect Multi-Store Retail Cloud Platform (Eleventa Pos) Foundation

We are seeking a highly skilled Solutions Architect for the foundational phase of a multi-phase project. The goal is to build a robust cloud dashboard that consolidates data from multiple Eleventa POS stores located in Guatemala. This initial phase is critical for establishing a solid technical foundation for the entire platform.

Deliverables for this foundational phase include:

1.  Comprehensive Requirements Document: Develop a detailed document outlining the full 10-phase vision for the platform. We will provide the initial scope for expansion.
2.  Technology Stack Recommendation: Propose a recommended technology stack with clear justifications. While we prefer TypeScript, Next.js, and PostgreSQL, we are open to exploring well-reasoned alternatives.
3.  Cloud Infrastructure Setup: Configure the complete cloud infrastructure, including selection and setup of the hosting provider, database services, file storage solutions, and a continuous integration/continuous deployment (ci/cd) pipeline.
4.  Database Schema Design: Create a detailed database schema covering essential entities such as stores, users, sales, products, inventory, expenses, and cash cuts.
5.  API Contract / OpenAPI Specification: Develop a comprehensive API contract and OpenAPI specification for all endpoints planned across the current and future phases of the project.
6.  Repository Setup and Environment Configurations: Establish the project repository with proper environment configurations for development, staging, and production. This also includes the creation of a basic landing page.

Acceptance Criteria:
Upon completion of this phase, the deliverable will be a production-ready empty platform featuring a functional login screen, a healthy and automated ci/cd pipeline, a thoroughly documented database schema, and a comprehensive written architecture document.

We are looking for a freelancer with strong expertise in cloud architecture, database design, and modern web development practices. Experience in the retail or Point of Sale (POS) domain is a significant advantage.
