Saas: Rate Calculator & Engangement Calculator for Influencers

Description

I’m building a simple, web-based SaaS tool for social media influencers. It needs two core features:
Rate Calculator (we can go into more detail when accepted):•⁠ ⁠Inputs: follower count, average reach/engagement rate, platform (Instagram, TikTok, etc.) - we have the data for the range of pricings•⁠ ⁠Outputs: suggested price per post/story/video (this will come as a range) and potential ROI (based on our engagement rate calculator)
Engagement Calculator (we can go into more detail when accepted):•⁠ ⁠Inputs: Influencers @ which will pull in their open source information on the IG API. •⁠ ⁠Outputs: engagement rate % for the last 10 paid posts and 10 organic posts (per following, per reach, per impression, per engagement)
Key Requirements:•⁠ ⁠Responsive user interface (desktop + mobile)•⁠ ⁠User authentication (signup/login) and dashboard to save past calculations•⁠ ⁠Clean, easy-to-read results (tables or simple charts)•⁠ ⁠Well-documented code and deployment instructions
Who You Are:•⁠ ⁠A full-stack developer comfortable with React (or Vue) and Node.js (or Python/Ruby)•⁠ ⁠Experienced in building calculation tools and user dashboards•⁠ ⁠Detail-oriented, communicates clearly, and meets deadlines
Please include in your proposal:•⁠ ⁠Brief outline of your approach•⁠ ⁠Examples of similar projects you’ve done•⁠ ⁠Estimated timeline and cost
Looking forward to working with someone who can deliver a reliable, maintainable tool.
