I have a small middleware layer that sits between two SaaS platforms, receives raw JSON, reshapes it, performs a few calculated roll-ups, and then pushes the cleaned payload back out through a remote API. The work is 100 % back-end: no HTML, no JavaScript, no database, just pure PHP. What I need you to do • Modify incoming data structures so they match the target schema (field mapping, nesting, key renaming, type casting). • Aggregate sets of records into concise summaries before dispatch (totals, counts, grouped objects). The code has to be clean, readable and function/procedural oriented, making smart use of native array functions, generators. We use our own framework based on vanilla PHP. Deliverables • A self-contained PHP that accept a JSON string or a GET/POST and return the transformed output after contacting backend. • Brief inline docs and a README that outline the transformation logic so I can extend it later. I’ll provide the current JSON examples, target schema, and the endpoint details as soon as we start. If you enjoy taming arrays and crafting elegant transformation pipelines, this will be a quick, focused gig for you.

Hi, This is exactly the kind of work I enjoy—clean PHP data transformation pipelines. I’ve built similar middleware layers where raw JSON is normalized, reshaped, and aggregated before being dispatched to external APIs. I’m comfortable handling: complex field mapping, nesting, and type normalization aggregation logic (grouping, roll-ups, computed summaries) writing clean, function-oriented PHP using native array tools and generators I’ll deliver a self-contained, readable script with clear transformation steps and minimal dependencies, along with concise inline docs so it’s easy for you to extend. I can start immediately once you share sample payloads and schema.

Hi, I've built several JSON-to-JSON transformation layers in vanilla PHP for SaaS integrations, so your project feels right in my wheelhouse. My approach would be to create a clean, procedural pipeline: first a mapping layer that handles field renaming, nesting restructures, and type casting using `array_map`, `array_combine`, and `array_walk_recursive`, then an aggregation layer leveraging `array_reduce` and generators to produce your roll-up summaries efficiently without bloating memory. The final module will handle the outbound API call via cURL and return the transformed response. I can start immediately once you share the JSON samples and target schema — happy to jump on a quick call to nail down edge cases before I write a single line.
