Full-Stack Dev for IIS + SQL WebApps

?️ Project Title:
Multi-Application Web Platform on IIS + MS SQL (Property Management, Vacation Rental, Estimating, eCommerce)

? Description:
I'm looking for a skilled full-stack web developer or team to help design, build, and deploy several interconnected applications hosted on IIS using Microsoft SQL Server as the backend.

The platform will be modular, with each application operating independently but sharing a consistent authentication model and UI. All apps will be hosted on Windows Server with IIS and should be responsive and mobile-friendly.

Photo/document storage (per property or tenant)

Communication portal for messaging

Letter generation/archiving (from manager to tenant)

Tenant contact and lease tracking

Manager dashboard for property status overview

? 2. Vacation Rental Listing Portal
A public-facing site where vacation rentals can be:

Listed by property owners or managers

Ability to save, edit, and duplicate estimates

? 4. Ecommerce Stores (Shoes & Perfume)
Two nopCommerce-based eCommerce sites:

Dropshipping model using suppliers who allow rebranding

Custom themes and branding (using my name/logo)

Automated order processing, supplier integration, and shipping

Focused on:

All types of shoes

Ability to scale and add affiliate integrations later

? Tech Stack Requirements:

IIS hosting experience

MS SQL Server (design and optimization)

QR code generation and scanning

Bootstrap or Tailwind CSS for responsive UI

nopCommerce setup and customization

Experience working with payment QR services (Zelle, Venmo, PayPal, etc.)

? Deliverables:

? Bonus if you have experience with:
Multi-tenant app structure

Shared login/authentication across apps

Integrating third-party APIs (shipping, payments, calendar sync)

? Start Immediately:
I'm ready to get started and have hosting ready. You may begin with one application first (Property or Estimator) and expand into others as we go.

Relevant projects or live demos

Estimated time to deliver Phase 1 (Property Management or Estimating)
