I’m preparing a MySQL-based solution whose main purpose is to integrate cleanly with several external systems. The focus is on building a solid schema, writing the necessary procedures and views, and putting in place the connection logic so data can flow bidirectionally without conflicts or performance hits. Here’s what I need from you: • A well-normalised MySQL database schema tailored for smooth data integration with third-party platforms (CRM, e-commerce, internal apps—exact mix will be finalised together). • Scripts or API-level routines that move data in and out reliably, including transformation rules and error handling. • Indexing, backup routines, and performance tuning that keep the store responsive at scale. • Clear, developer-friendly documentation so my in-house team can extend or troubleshoot the setup later. I’m happy to walk you through the existing tech stack, provide sample payloads, and agree on milestones for design, build, and hand-off. If your portfolio shows similar integration work with MySQL, let’s get started.
