E-commerce website development.

I recently moved my e-commerce website from Wix to Shopify after some security concerns. Unfortunately somewhere along the line things got worse, and I am now in a pretty desperate situation to rebuild it, and have the correct security measures in place.
I would still like to use Shopify as it’s easy enough to maintain with daily operations, but need help developing the backend and customising the theme. I have two themes in mind, their standard and one I purchased for the aesthetic side of things. Ideally I would like to combine the two. I am open to perhaps moving platforms and the domain again but there is an urgency. The website is currently down to prevent client data being stolen, but if you need to assess the site, let me know? General Requirements: - Home Page - About Page - Collection Pages and 1 main shop page (with the ability to filter in multiple ways) - Product Page - Alphabetical Index Page with each item linked to another individual page. (My website hosts merch from over 900 bands. The individual pages linked are to each of their “profiles”) - The usual ecom pages; customer accounts, payments etc - Super speedy response. My site currently has over 3000 products and often very high res images. - In depth analytics capabilities - Email Host/Service What I can provide: - Copy - Content - Images I hope that covers everything you need from me initially. Please do let me know if your need more information to assess whether you’d be able to assist. Thanks in advance!

Phishing projects

I am seeking a skilled and reliable developer (or development team) to help me build a cybersecurity awareness training platform inspired by KnowBe4, but simplified for small businesses like law firms, clinics, and hotels.
Project Goals: The platform should help organizations train their employees by simulating phishing attacks and providing interactive security awareness education. ⸻ What I Need Built: • Phishing Simulation System: Send realistic-looking phishing emails to users across an organization. Emails should be customizable, and not all employees should receive them at once to avoid spreading alerts. • Landing Page After Click: If an employee clicks the fake email, it should redirect to a warning page saying, “Oops, you got phished,” followed by a short awareness message and an embedded 30-second educational video. The page should mention the company and employee name for a personalized effect. • Training Dashboard: Admins (like HR or IT) should be able to log in and see who clicked, who completed training, and export reports (PDF or CSV). • Content Management: Ability to upload awareness videos or short quizzes in the backend. • Email Campaign Control: Admins should be able to schedule phishing emails and awareness campaigns.
Skills: Amazon Web Services, TypeScript, Laravel, Django, MySQL, PostgreSQL, Git, React, ExpressJS, FastAPI, Next.js, Vue.js, Docker, Linux, CI/CD
