PHP / CodeIgniter Developer — E-Commerce Catalog Integration Part-Time | 5 hrs/day, 5 days/week | $2/hr About the project This is a jewelry e-commerce site built on PHP CodeIgniter with a MySQL backend. The site pulls product inventory from five separate vendor/manufacturer sources, each with its own data structure. Our current priority is unifying these into a consistent shopping experience: a single mega-menu navigation, category/listing pages, product detail pages, and cart — all working correctly regardless of which vendor a given product comes from. Foundational architecture (data model, controllers, and navigation spec) is already in place. We need a developer to take this the rest of the way: wire it into the live site, build out the remaining views, resolve outstanding data gaps, and ensure everything works end-to-end against the production database. What you'll be working on Completing the listing → detail → cart flow across all 5 product sources Building/finishing CodeIgniter view templates to match the existing site theme Writing and testing filter logic (by style, shape, metal, collection, price, etc.) against real MySQL data Resolving legacy database debt — the app has a large number of old, duplicate, and inconsistently-structured tables from a previous business/template; part of this role is helping sort out what's live vs. dead code Implementing a unified cart that correctly tracks which vendor/table a product came from, so "view details" and checkout stay accurate General CodeIgniter MVC development: controllers, models, routing, views Working from existing technical specs (we maintain detailed documentation of table structures, filter mappings, and navigation requirements) and knowing how to ask sharp clarifying questions when specs and reality don't match Required skills & experience 3+ years of PHP development, with real production experience in CodeIgniter (not just Laravel/Symfony — CodeIgniter's conventions matter here) Strong MySQL skills: writing performant queries across multiple tables, understanding schema design, comfortable with JOIN/UNION decisions and indexing Experience with e-commerce systems: product catalogs, cart/checkout logic, category and filter-driven browsing Comfortable working in a legacy codebase — reading unfamiliar code, identifying dead vs. live logic, and making safe, incremental changes without breaking existing functionality Front-end competency: HTML/CSS/JavaScript, and ability to match an existing site's visual theme rather than defaulting to your own style Experience with data import/migration — CSV/Excel to MySQL, handling inconsistent or messy source data Git or equivalent version control Strong written communication — this project has multiple data sources with real ambiguities (missing fields, inconsistent formats, unconfirmed values), and we need someone who documents assumptions and flags gaps clearly rather than guessing silently Strongly preferred Prior experience integrating multiple vendor/supplier product feeds into one storefront (drop-shipping, marketplace, or B2B jewelry/diamond industry experience is a big plus) Experience with jewelry-specific product attributes: 4Cs (cut/clarity/color/carat), metal types/karats, stone shapes — understanding why these matter to filtering and search SEO-aware development: clean URL structures, avoiding duplicate/thin content across large combinatorial catalogs Experience building or maintaining mega-menu/faceted navigation systems Comfortable reading and executing against detailed technical specs (we'll provide schema docs, filter-mapping sheets, and architecture notes) Soft skills that matter for this role Asks good questions before writing code, not after something breaks Comfortable saying "this doesn't match what you told me, can you confirm" rather than guessing and shipping it Documents changes clearly enough that someone else (or future-you) can pick up the work Works well async — this is a spec-driven, documentation-heavy project

Hi, The key here is unifying five different vendor schemas without breaking the existing CodeIgniter MVC architecture, especially around filters, product IDs, and vendor-aware cart logic. I can work through the existing models/controllers first, identify live vs. legacy tables, then complete the listing → product → cart flow and build reliable MySQL filtering against the real production data. I’ll also keep the existing UI/theme and document any data inconsistencies instead of guessing. I’m comfortable working incrementally in a legacy CodeIgniter/MySQL codebase with Git, vendor feeds, catalog filtering, and e-commerce flows. Best regards, Fizza Nadeem

Hi, I'm Denis, a full-stack developer with experience merging vendor feeds into unified e-commerce systems using CodeIgniter and MySQL. I’ll help complete the integration of your five jewelry vendor feeds into a cohesive catalog, ensuring consistent navigation, filtering, and cart behavior. The key challenge is normalizing diverse data structures without disrupting the existing experience. I’ve tackled similar projects, mapping supplier schemas to a common model, cleaning legacy data inconsistencies, and implementing robust filtering to handle real-world gaps like missing fields or formats. Here’s my approach: - Audit the current data model and specs for gaps or mismatches. - Build the remaining CodeIgniter views, aligning them with the existing theme. - Implement unified cart logic to track vendor-specific attributes. - Write performant MySQL queries for filtering and category browsing. - Test each component incrementally against the live database. The main risk is legacy database debt—old tables or inconsistent structures. I’ll mitigate this by carefully auditing the schema, documenting assumptions, and making gradual changes to preserve functionality. I’m ready to start immediately. Let’s discuss the details. Thanks, Denis

Five vendor feeds into one cart means the product ID alone isn't enough, the source table has to travel with every add-to-cart call or "view details" silently points at the wrong row. I'll finish the listing to detail to cart flow across all five sources, wire the filters (shape, metal, collection, price) against the live MySQL, and match views to the existing theme. Dead legacy tables get flagged, not touched, until you confirm. I can jump in today. 1) Is the vendor identifier already on the cart session, or do I add it? 2) Which of the five sources is furthest from spec right now? Ready when you are. Thanks Shayan

ASAP - EXPERT I have strong PHP/CodeIgniter and MySQL experience, including production e-commerce systems, catalog integrations, filtering, cart workflows, and legacy codebases with inconsistent data structures. I’m comfortable working across MVC controllers, models, routes, views, SQL joins/unions, indexing, and front-end templates while preserving the existing architecture and design. I’ll unify the five vendor sources through a reliable product flow, complete the listing/detail/cart experience, implement accurate filters, resolve data gaps, and document assumptions instead of guessing. I’ll work incrementally with Git, test against real production-style data, and clearly flag schema or specification conflicts before making changes. The key advantage I bring is a careful, data-driven approach that makes a complex multi-vendor jewelry catalog feel like one consistent storefront.

Your core issue is not just “CodeIgniter work” — it’s making five messy vendor catalogs behave like one clean storefront without breaking live production data. I’ve solved that exact pain point before: inconsistent schemas, legacy tables, and unified catalog flows where product source tracking had to stay intact through listing, detail, cart, and checkout. I can wire your existing architecture into the live site, finish the CI views, and build the filter logic so it works reliably against MySQL data. I’d approach this by mapping live vs. dead tables, tightening the controllers/models, and keeping every product tied to its vendor source in the cart flow. I also document mismatches clearly so nothing gets guessed silently. I’ve handled similar multi-feed e-commerce integrations and legacy CodeIgniter rebuilds before, including catalog normalization and theme-matched view work. Best, NexLoom Labs

Hi, I can take over the existing CodeIgniter architecture and complete the five-source catalog flow without flattening vendor-specific data into fragile assumptions. I’ll first trace the live controllers, models, routes, tables, and cart session structure against your documentation and production schema. My approach would introduce a normalized product adapter layer that preserves each vendor/table identifier while exposing consistent listing, detail, filtering, and cart data. I’ll audit queries and indexes, document dead or ambiguous tables, test filters against real records, and make incremental Git changes that retain the current theme and checkout behavior. I’m comfortable working asynchronously from detailed specifications and will explicitly flag missing fields or schema conflicts before implementing dependent logic. Which CodeIgniter version is running, and does the existing cart already store both a vendor/source key and the source product ID? Regards, Houssame
