looking to have a demo app looked over and fine tuned for implementation. It would be an individual project only reviewed with myself. I am looking for someone who is proficient in streamlining workflows and integrating API.

We're a small SaaS for makers (candle/soap/craft businesses) called Makers Manager. We need a Shopify integration built. This is a focused engagement, not a build-from-scratch project: our app already exists (React + TypeScript + Supabase), and I handle most day-to-day development myself. What the integration does (this is the whole MVP): - Sales in: pull orders from each connected Shopify store into our app (webhook + a reconciliation fallback, idempotent so re-syncs never duplicate). - Products + inventory out: push product catalog and inventory levels from our app to Shopify. Our app is the source of truth for stock. When a Shopify sale comes in, we recompute stock and push the authoritative number back out. - Multi-tenant: every one of our customers connects their own Shopify store via a one-click "Connect and authorize" flow. No customer should ever have to generate an API token — this must be a proper public Shopify app using OAuth. Scope of your work: - The public Shopify app: OAuth authorization-code flow, secure per-workspace token storage (server-side only, encrypted), connect/disconnect. - Orders-in and inventory/products-out sync (GraphQL Admin API; inventorySetQuantities for per-location stock). - SKU matching, with unmatched line items surfaced for the user (never silently dropped). - Compliance to pass review: protected-customer-data request/attestation and the three mandatory GDPR webhooks (customers/data_request, customers/redact, shop/redact). - I'll build the UI and the CRUD-y pieces myself. You must have (please don't apply otherwise): - Shipped at least one public Shopify app that passed Shopify's app review. Include a link or the app name. This is the #1 requirement — I need someone who's already done the OAuth + protected-data + compliance path, not learning it here. - Real experience with the Shopify Admin GraphQL API, webhooks (HMAC verification), rate-limit/backoff, and the Inventory API (per-location levels). - Comfortable with a Postgres/Supabase backend and row-level security for multi-tenant data isolation. Nice to have: inventory/COGS domain experience; prior maker/commerce tools; Etsy or other marketplace APIs (we'll do those next). How we'll work: - Fixed-price, milestone-based. The first step is a small paid trial task (a few hours): stand up the OAuth handshake against a Shopify dev store and store a token securely. If that goes well, we do the full build in milestones. - I'm responsive and technical, so you won't be waiting on me or guessing at requirements — there's a detailed spec ready to share.

We are seeking an elite, independent Bubble.io expert to take over, optimize, and finalize a multi-portal educational therapy and CRM application (LJL Platform) that is currently 70% complete. We have successfully recovered 100% master admin ownership of our Bubble repository from our previous developer. We are avoiding traditional coding agencies. We want a highly precise, transparent independent freelancer who excels at database architecture, conditional logic, and clean third-party API configurations. You will be handed a completely pre-written, itemized 30+ feature specification list covering our exact operations, removing all discovery lag. This project is structured into two fixed-price delivery phases: PHASE 1: PLATFORM AUDIT & DIAGNOSTIC ENGINE (Fixed Budget: $2,500) Verify the current database health and build out our core educational logic: • EF Assessment Module: Build a framework to host diagnostic testing fields using standard jsPsych data hooks for intra-student benchmarking (tracking raw accuracy and reaction speed over time). • Conditional Logic Pathing: Code backend workflows that evaluate test scores to automatically flag and assign customized student learning paths from our library. • Clinical Validation Portal: Design a secure, native dashboard for our chief administrator (April) to review telemetry data and manually approve/override student placements with a single click. • Gatekeeper Business Rules: Enforce a strict database rule verifying if a minimum $110 qualifying assessment fee has been paid before unlocking specific enrollment tracks. PHASE 2: COMMUNICATIONS, CRM & MARKETING AUTOMATION (Fixed Budget: $5,000) Connect our external pipelines and optimize our daily scheduling/business operations: • Lead Ingestion & Twilio Drips: Connect webhook receivers from incoming web intake forms to instantly generate CRM lead records and trigger 4-tier automated text sequences via Twilio. • Operational Variable Quoting: Program a live multi-variable pricing matrix that calculates custom client quotes based on situational variables (number of residents, pets/shedding habits, learning tracks, and timeline urgency). • Local SEO & Web Syncing: Securely configure API components (Google LSA, Meta Graph) to seamlessly cross-post client reviews and milestone updates back to our marketing site. • Core Operational Rescheduling: Clean up scheduling engine rules to enforce strict business policies (6-hour cancellation windows, credit/no-credit rules, and tutor payment tracking logs). *WHAT IS EXCLUDED:* We are NOT building a custom LMS, custom gamification engines, or automated Gusto payroll integrations. We are keeping the app lean and utilizing external software for those tasks to protect our timeline. Requirements: • Expert-level mastery of Bubble.io database normalization, privacy rules, and the API Connector. • No agencies. Individual freelancers only. • Ability to log in, complete a 48-hour codebase audit, and provide weekly functioning milestone updates. To Apply: 1. Confirm you are an independent freelancer. 2. Share a quick summary of a "rescue project" you successfully took over and finished on Bubble. 3. Confirm your availability to begin an immediate audit and stay aligned with our fixed milestones. CRITICAL RESCUE REQUIREMENT (Verification & Completion): Because our relationship with the previous developer was frozen abruptly, we do not know exactly which parts of the existing 70% build are fully functional or where the database logic might be broken. Your contract will begin with a paid, mandatory 48-hour Codebase & Database Audit milestone. As the incoming developer, you are responsible for testing the existing portals (Admins, Tutors, Parents), identifying any broken workflows, and fixing them. Your final project delivery must ensure that the entire unified platform—both the existing core infrastructure and the new Phase 1/Phase 2 modules—functions flawlessly together. You are not just adding features; you are completing the system. SEE ATTACHED PDF FILE (LJL APP MASTER RFP) FOR COMPLETE PROPOSAL DETAILS

The product definition is substantially complete. A comprehensive Product Requirements Document (PRD) and detailed Figma designs have already been prepared, allowing development to begin from a well-defined product foundation.

𝗪𝗵𝗮𝘁 𝗬𝗼𝘂'𝗹𝗹 𝗗𝗼: The first milestone will focus on planning—not coding. You'll review the PRD and Figma designs, then propose: ★ System architecture ★ Database design (ERD) ★ Recommended technology stack ★ Infrastructure approach ★ Project milestones ★ Development timeline and estimates Once these proposals are reviewed and approved, development will proceed through fixed-price milestones.
