About the Project:

We're hiring a senior WordPress plugin developer to build a custom Stripe Connect Express marketplace payment plugin for an existing WordPress + WPJobster site.

The plugin handles the full payment lifecycle for a marketplace selling pre-recorded service sessions: buyer checkout via Stripe Checkout, destination charges with platform fee separation, 30-day payout holds, multi-jurisdiction tax via Stripe Tax with a 9-setting multi-code architecture, audit-grade financial recordkeeping for EU and US compliance, and an independent third-party code audit at the final milestone.

The plugin is 19 custom DB tables, 13 admin settings groups, four PDF document types (three invoice variants + buyer receipt), 47 editable email templates, and 22 conflict tests across five milestones. The full developer briefing is approximately 860 KB and is shared only after a paid live working session confirms technical fit (more on this below).

Platform Stack:

- WordPress 6.7+ with WPJobster theme as the marketplace foundation
- PHP 8.1+ / MySQL 8.0+
- 19 custom DB tables (not WordPress post types)
- Stripe Connect Express (destination charges, manual transfers, 30-day payout hold)
- Stripe Checkout (hosted) with embedded payment_intent_data for marketplace flows
- Stripe Tax with multi-jurisdiction architecture (9 admin settings; CPA-confirmed product codes)
- AWS SDK for PHP for S3 document storage (~38,000 PDFs/year at 100 sellers, ~384,000 over 10-year EU retention)
- Composer for dependency management; PHPUnit for test coverage
- Standard WordPress hooks, cron, admin UI conventions

What You'll Build (5 Milestones):

- **M1 — Foundation:** Plugin skeleton, all 19 DB tables, full 13-group admin settings panel, dependency check, integration verification with Jobster
- **M2 — Payment Flow:** Sessions via Stripe Checkout with destination charges, platform fee separation, 30-day payout hold state machine
- **M3 — Tax & Documents:** Stripe Tax integration, four PDF document types with proper VAT legal text, multi-jurisdiction handling
- **M4 — Tips, Featured Jobs, Refunds:** Additional payment flows, refund routine with edge cases
- **M5 — Hardening & Audit:** Security audit report, integration verification, PHPUnit test suite, **independent third-party code audit** (we hire this auditor independently of you)

Hiring Process — Verification Built In:

We use a multi-stage flow designed to filter for actual individual technical capability:

1. **Application screening** — your application + 5 screening questions
2. **Vertical disclosure (written)** — we share the business vertical so you can opt out cleanly if it's not a fit for you, before any time investment
3. **Pre-NDA Zoom (~30 min)** — fit check (NOT a technical interview)
4. **Scope Summary delivery (~45 min read)** — a confidential mid-tier scope document, before any contract
5. **Paid live working session (~2-3 hours, $300 paid for your time)** — Zoom with screen-share, architectural discussion + bounded live coding task, with a senior technical reviewer present. This is the verification step that matters most. You're paid for the session regardless of whether we proceed.
6. **NDA + full briefing** — released only after the live session passes
7. **Contract** — milestone-based Upwork escrow

If you're not comfortable with the paid observed verification step, this isn't the right project for you. We've found it's the only reliable way to verify what we need to verify, and senior developers confident in their work generally welcome it.

What We're Looking For:

Strong candidates have:

- Built a Stripe Connect Express marketplace before (or comparable level of Stripe Connect depth) — destination charges, manual transfers, custom payout schedules
- Hands-on experience with Stripe Checkout (hosted) with payment_intent_data for marketplace flows
- Built a payment provider abstraction layer in PHP (non-negotiable architectural requirement for this project)
- Hands-on AWS SDK for PHP experience with S3 + pre-signed URLs (not just WP Offload Media)
- Comfortable with rigorous fixed-price engagements with clear milestones, staging-site-only development, and independent third-party audit at final milestone
- Comfortable with paid observed live verification before contract signing

This is a long engagement (9-14 weeks calendar time) for a senior developer. We're not looking for the cheapest bid — we're looking for the right developer who can deliver a financially audit-clean plugin.

How to Apply:

Please answer all five screening questions thoughtfully. Specific lived-experience details (actual error messages, specific webhook events, concrete implementation choices you made for specific reasons) read much stronger than generic well-structured answers.

If your application reads strongly, you'll hear back within 5 business days with an acknowledgment and the vertical disclosure. From there, the multi-stage process moves at the pace we can both sustain.

• Have you built a Stripe Connect Express marketplace with destination charges, application fees, and a custom payout hold? Link a live example or GitHub repo, describe your role (solo/lead/contributor), and give rough scale (sellers or monthly volume).
• Describe one Stripe Connect Express edge case from your own work that surprised you — what you expected, what actually happened, how you handled it. One specific incident with concrete detail (actual error, webhook event, resolution).
• PHP payment provider abstraction layer is a non-negotiable requirement here. In 3-4 sentences, describe how you'd approach this — including one specific tradeoff you'd watch for. We're evaluating how you think, not length.
• Have you built Stripe Checkout (hosted) with embedded payment_intent_data for destination-charge marketplace flows? If yes, note one specific implementation detail (e.g., terms_of_service_acceptance, automatic_tax, success_url patterns).
• Confirm hands-on AWS SDK for PHP experience with S3 + pre-signed URL generation (not just WP Offload Media). Describe one project using the SDK directly with one specific detail (IAM policy approach, expiry handling on email links, bucket structure).

We are a nonprofit organization seeking a senior engineer to take ownership of two existing, related web applications, stabilize them, and bring them to go-live. This is a stabilization-first engagement: establishing a reliable, documented baseline, then completing what is required for launch.
Stack: Node.js/Express, AWS (EC2/Nginx, Amplify), Sanity CMS, Supabase (PostgreSQL), NodeBB (community), Salesforce (CRM).
The work:

Stabilize the infrastructure: correctly separated staging and production environments, a reliable deployment process with an approval step, and no hardcoded values standing in for real connections.
Get both applications fully functioning and live, with working test accounts.
Deploy and connect the community platform.
Complete CMS integration so all content is managed through the CMS, with tested publishing automation.
Deliver architecture and setup documentation, and bring both sites to a stable go-live.

Requirements:

Demonstrable experience with Node.js/Express and AWS EC2/Nginx deployments, including backend and database work.
Experience taking over and stabilizing existing codebases, not only greenfield builds.
Strict security practices: no hardcoded values or credentials, proper .env / secrets management, secure webhook validation, least-privilege access.
All work performed under organization-owned accounts and repositories we provide (no personal accounts).
CMS-managed content (no hardcoded content as a substitute for proper integration).
Documentation treated as a deliverable.
Willingness to coordinate with our team for QA verification, with nothing deployed to production without testing and our approval.

• You're taking over a codebase with little or no documentation. Walk me through your process for the first week how do you get oriented and decide what's safe to change?
• Imagine a client asks why a feature isn't working, and you discover it was never properly connected a hardcoded placeholder had been masking that it was incomplete. How would you handle that conversation?
• Do you use AI coding tools in your work? If so, how do you use them, and how do you handle them around code or systems that touch sensitive data (e.g., member or donor records)?
• Tell me about a project you inherited that turned out to be in worse shape than expected. What did you find, and how did you handle it?
• Phase I of this project will be milestone-based only. Are there any issues with this?

We are seeking a skilled freelancer to create and optimize existing listings on Amazon. The ideal candidate will have experience in Amazon listing optimization and be able to enhance product visibility and sales.

Responsibilities include creating new listings, optimizing existing ones, creating images, creating videos, creating A+ content, creating variations, and ensuring compliance with Amazon's policies. Experience ensuring listings are keyword optimized is preferred. Attention to detail and a strong understanding of Amazon's algorithms are essential.

Experience with ad creation and campaign management is preferred but not required for longer term opportunity. Experience with Shopify listing creation, standardization, and SEO optimization is also preferred but not required for longer term opportunity.

• Please list any experience with tools used to conduct keyword research, create images, create videos, standardize listings, and/or perform competitor analysis.
• Describe your recent experience with similar projects

Seeking an Amazon KDP specialist and Amazon Ads manager for a faith-based nonfiction book series. Responsibilities include managing book listings, optimizing ad campaigns, and analyzing performance metrics. This is a long-term partnership role, not a one-time hire. Ideal candidates will have experience in Amazon KDP and PPC advertising, with a focus on maximizing visibility and sales.

I need a clean, browser-based system that lets my HR staff create professional employee ID cards in minutes. All templates (we will hand you at least 25 layered designs) should live in our Amazon S3 bucket; the app only has to pull what’s there, show a thumbnail gallery, and let the user pick the right one.

Workflow I am picturing:
• HR selects a template, uploads a JPEG headshot, and sees it auto-fit into the designated photo area.
• Dynamic form fields then appear—name, department, certifications, cross-training info, etc.—matching that specific layout.
• When a department requires it, the back side must include a Pdf417 barcode that encodes the data string we pass from the form.

Quality is critical because we print in-house on PVC stock; the output you generate should be a high-resolution, print-ready PDF (front and back in one file) that preserves all template colors and bleed settings.

Please build:
• Secure login for our HR team (role: “Creator”) and an admin dashboard where I can add, edit or archive templates.
• S3 integration for templates, final PDF storage, and optional automatic cleanup of older drafts.
• Simple image tools—crop, rotate, brightness—so staff can adjust photos without third-party software.
• A small configuration panel where we can switch the barcode on or off per department, and edit the Pdf417 data format ourselves later.

Acceptance will be based on:
1. Selecting any of our 25 templates and producing an error-free PDF in less than 10 seconds.
2. Barcode scans correctly on at least two standard scanner apps.
3. All data saved in S3, accessible only to authenticated users.
4. Clear deployment notes so we can host on our existing AWS stack.

JPEG is the only mandatory photo format today, though the code can stay flexible for PNG or TIFF later. Let me know the tech stack you prefer and an estimated timeline, and we’ll move forward right away.

I want to buy the Pixer script and need a professional to install it and make some modifications to it.
https://codecanyon.net/item/pixer-react-laravel-multivendor-digital-marketplace/36383345
Technical Scope of Work (SOW): Pixer Marketplace Customization
Dear Developer, please strictly follow these technical requirements and blueprints to deploy, fully localize, and optimize the Pixer (Next.js/React & Laravel) Marketplace:
1. System Architecture & Deployment Setup
• Infrastructure: Deploy the backend (Laravel) and frontend (React/Next.js) on a Cloud VPS instance (such as DigitalOcean Droplet or Hetzner Cloud). Do not use shared hosting.
• Storage Decoupling: All digital assets, products, ZIP files, and large seller uploads must be hosted externally on Amazon S3 or DigitalOcean Spaces. Never store downloadable products directly on the local application server.
2. Search Engine Upgrade (Critical)
• Problem: The default database SQL LIKE queries cause massive performance bottlenecks and lack semantic Arabic comprehension.
• Requirement: Integrate Laravel Scout and bind it to Meilisearch (installed on the server). The search bar must provide instant results, support partial matching, and fully support Arabic typo tolerance (Fuzzy Search).
3. Core Bug Fixes & UX Optimization (From Client Reviews)
• Next.js Client Routing Fix: Optimize Nginx routing/rewrites and Vercel/Cloud configs to completely resolve 404 broken link errors when users trigger a hard browser refresh on dynamic store/vendor portfolio links.
• Automated Image Optimization: Implement an automated image processing pipeline (using Intervention Image or Next/Image) to auto-compress and convert all seller-uploaded covers/previews to lightweight .WebP format.
• Graceful Payment Error Handling: Refactor checkout error boundaries. If a payment fails or a credit card is declined, show clear user-friendly notifications instead of frozen pages or unhandled raw code exceptions.
4. Arabic Localization & RTL Implementation
• Translation Files: Map out all strings into localized JSON translation trees (e.g., ar.json).
• True RTL Alignment: Adapt the Tailwind CSS setup to fully change document orientation using dir="rtl". Ensure that cart icons, grids, slide menus, and sidebars completely flip orientation without element overlapping.
5. Local Payment Gateway Integration (Tap or PayTabs)
• API Integration: Programmatically connect the payment flow to Tap Payments or PayTabs API.
• Supported Rails: Must seamlessly process local payment options including Mada, KNET, Benefit, and native Apple Pay.
Vendor Balance Accounting: Because local gateways aggregate funds to the main platform merchant account, you must build/ensure
