We are interested in developing a web app that will allow us to automate a lot of the administrative tasks we need to do to carry out our work. The app will serve three main functions: 1) Provide a simple and easily accessible interface that will allow users to submit expense information that will be automatically stored in our organization's Google Drive. 2) Allow for admin to review this information and engage in a dialogue with the user if necessary. 3) Track all expense data in an organized way to a) allow users to view project expense summaries and b) allow admin to create and generate expense reports. Attached is an overview of how each interface should articulate with the others as well as a detailed summary of what each interface could look like. Note that the details here are not comprehensive and questions are expected, but the general shape is there. Note that these interfaces will need to effectively and seamlessly articulate with one another as well as external systems like Quickbooks.

We are looking to do a new build of our patch bay label designer tool. Customers are currently able to pick their model of patch bay, add text labels, colorize, and group. They can then checkout and it creates print ready artwork for our team to produce. The UI is a bit clunky and there are some features we want to add such as an admin tool to add and edit labels. You can see the current tool here: https://create.traceaudio.com/

We are a music publisher located in the United States. We previously hired a Shopify app developer to create for us a custom digital-download app that would automatically watermark digital files with the customer's information before delivering it to the customer. The app still functions, but unfortunately parts of it have broken making it harder for customers to find their digital files. Customers used to receive a separate email with their digital files, but now can only access their digital files with a small link in their order confirmation email. We would like customers to receive a separate email with their digital files like how the app originally functioned. Once that has been fixed, we would also like the digital files to be accessed straight from the "order complete" screen as well as in their account profile. We essentially want this custom digital download app to function identically to the base "Digital Downloads" Shopify plugin on the customer side.

I have a Webflow website that is 95% complete. The design and build are largely done — I just need an experienced developer to come in and execute a specific punch list of fixes. No guesswork, no interpretation — you will receive a detailed checklist with every change clearly outlined. This is not a build-from-scratch project. You will be inheriting an existing Webflow project and working from a clear, itemized list. If you're comfortable jumping into someone else's Webflow setup and executing precisely, this is a straightforward engagement. Fix categories include: Resolution & scaling — site was designed on a 1728×1117 base (MacBook Pro 16"). Must scale correctly and be explicitly tested and approved across all of the following breakpoints: Desktop: 1920px, 1728px, 1440px, 1366px, 1280px Tablet: 1024px, 768px Mobile: 475px, 425px, 390px, 375px, 320px Mobile fixes Browser continuity — Chrome and Safari must render identically Graphic resolution Spacing & layout inconsistencies All fixes will be clearly outlined in an Excel checklist provided at the start of the engagement. Every breakpoint listed above is in scope. No exceptions. What I'm looking for: Strong Webflow experience, especially with interactions, animations, and responsive behavior Comfortable working within an existing project structure Detail-oriented — pixel-perfect execution matters Please include your hourly rate or a fixed-price quote Figma file and full checklist provided upon engagement.

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.
