Description We are building Cardinal Hearts, a Stanford-centered digital wellness and anonymous peer support platform designed to help students navigate romantic relationships--share experiences, seek support, access personalized resources, and foster meaningful reflection in a psychologically safe environment. The platform will be fully accessible across both mobile and desktop devices, with a seamless, intuitive experience on each. We are looking for a talented full-stack developer to build a high-resolution functional MVP/prototype with scalable frontend and backend architecture. This is not a traditional social media platform — the interaction model should feel intentional, supportive, privacy-conscious, and community-centered. --- Core Features Frontend Development We need a modern, clean, responsive application that works seamlessly across: * Mobile devices * Tablets * Desktop/laptop browsers Key features include: * Anonymous posting feed * Post creation flow * Stanford-inspired branding/aesthetic * Tagging/filter system: * “Seeking Advice” * “Just Wanted to Share” * User onboarding/login flow * Saved/bookmarked posts * Ability to “follow/save” posts for later viewing * Personal Diary feature (see below) * Responsive UI optimized for both mobile and desktop --- Community Interaction Features We want engagement to feel emotionally supportive rather than performative social media. Features include: * “I Resonated” reaction button on posts * Anonymous resonance counts visible publicly * Optional sorting/filtering by most resonated posts * Private “This Didn’t Resonate” feedback option (not visible to other users; used only for internal analytics and personalization) * Aggregate engagement signals used to improve content surfacing and recommendations --- Diary Feature (Personal Reflection System) Each user will have a **Diary**, which serves as their personal timeline of activity and reflection. Core functionality: * All public posts automatically appear in the user’s Diary, organized by date * Users can also write **private diary entries** that are never shared publicly * Clear distinction between: * Public posts (community-visible + stored in diary) * Private reflections (personal only) Diary capabilities: * Chronological timeline view of all entries * Ability to filter between public and private entries * Optional tagging of entries (e.g., reflection, advice-seeking, personal note) * Centralized place to revisit personal experiences over time --- Mood & Reflection Calendar Feature We also want a reflective mood tracking system inspired by apps like *Natural Cycles*. When users reflect or write in their diary, they can optionally select a **mood using an emoji-based system** (e.g., “Anxious 😟”, “Sad 😔”, “Calm 🙂”, etc.). Core functionality: * Users can attach a mood to each entry (optional) * Mood input should be fast and lightweight (emoji + label selection) Visualization: Users can view their data in: * Daily view (mood + associated entries) * Weekly trends * Monthly calendar or heatmap visualization of mood patterns Purpose: This feature helps users identify emotional patterns over time by connecting: * Mood states * Life events/reflections * Written posts Example: A user may notice repeated “anxious” moods on days involving a specific relationship dynamic, enabling deeper self-awareness and reflection over time. The goal is to support insight, not diagnosis — helping users better understand emotional patterns and triggers. --- Resource Library + Personalized Recommendations We are also building a curated **digital resource library** populated with materials from Stanford’s SHARE (Sexual Harassment/Assault Response & Education) office. Library may include: * Books * Articles * PDFs * Support resources * Educational materials Features: * Admin upload and management system * Categorization/tagging of resources * Personalized recommendations based on: * User posts * Diary entries * Mood data * Tag usage Recommendation system: Can initially be rules-based (no need for full AI at MVP stage) Examples: * Users expressing loneliness may be shown community/support resources * Users seeking relationship advice may receive relevant reading materials Privacy and sensitivity are critical to design. --- Analytics Dashboard (Admin/Internal) We need a basic analytics dashboard including: * Total users * Daily/weekly active users * Posts over time * Most-used tags * Most resonated-with posts * Resource engagement metrics * Repeat visitor tracking Advanced visualization requests: * Calendar view of engagement activity * Heatmap-style visualization for user engagement over time * Trend tracking for usage patterns (daily/weekly/monthly) We are open to recommendations for the best charting libraries/tools. --- Backend Development Requirements * Secure Stanford-only login/authentication * Stanford SSO preferred if feasible * Otherwise .edu-based restriction system * Database architecture and setup * Anonymous posting logic (ensuring privacy separation from identity) * User accounts and diary storage system * Saved posts/bookmarking system * Tag and category management * Moderation/reporting tools (basic MVP) * Scalable backend structure for future expansion --- Preferred Tech Stack Open to recommendations, but currently considering: * React / Next.js * Node.js * Firebase or Supabase * PostgreSQL --- Ideal Candidate * Strong full-stack web development experience * Experience building social or community platforms * Strong UI/UX instincts * Experience with authentication and secure systems * Comfortable building privacy-first products * Strong communication and fast execution mindset * Product/design thinking is a plus Bonus if you have experience with: * Anonymous social platforms * Mental wellness or student-facing products * Recommendation systems * Data visualization dashboards --- Deliverables * Functional high-fidelity MVP/prototype * Clean, documented codebase * GitHub repository handoff * Deployed staging/testing environment --- To Apply Please include: 1. Relevant portfolio/projects 2. Recommended tech stack for this build 3. Estimated timeline 4. Estimated budget range 5. Your approach to: * Anonymous posting architecture * Diary + mood tracking system * Personalized recommendation system 6. Any suggestions or improvements based on your experience We are aiming to move quickly and begin development ASAP.

We're building a data-driven platform in the beauty/cosmetics space. We've already collected a very large volume of scraped product and brand data, and it's messy - inconsistent formats, duplicates, missing fields, mixed languages, and unreliable values. Your job is to turn that raw data into something clean and reliable, and to build the web application on top of it. This is not a quick gig. We're looking for someone to stay with us for roughly a year and grow with the product. What you'll be doing Building and maintaining a Next.js (App Router) front end and back end Designing and managing our Supabase setup (Postgres schema, RLS policies, auth, storage, edge functions) Cleaning, normalizing, and deduplicating large beauty datasets (this is a major part of the role) Building data pipelines to process and validate incoming scraped data Writing transformation/normalization logic (units, brand names, categories, ingredients, pricing, etc.) Setting up data-quality checks and monitoring Iterating on features with us as the product evolves You should have Strong production experience with Next.js and Supabase (please point to specific projects) Solid SQL/Postgres skills - not just ORMs Real experience cleaning and normalizing large, messy datasets (Python/pandas or similar is a plus) Comfort working with scraped data and all the inconsistencies it brings Good written English and reliable communication Ability to work independently and own your part of the product Nice to have Experience in e-commerce, catalog, or product-data projects Familiarity with data pipelines / ETL tooling Some ML/NLP experience for entity matching or text cleanup Budget We expect this to run around $4,000–$5,000 USD per month depending on experience and hours. This is a long-term commitment, so stability and quality matter more to us than the lowest rate. To apply, please include: Similar past work - links or short descriptions of Next.js + Supabase projects, and at least one data-cleaning/normalization project you've done. Your time zone and your typical available hours - we need to know there's reasonable overlap. Your expected monthly budget within the range above (or your rate if hourly). Applications that don't address all three points will not be considered. A short note on how you'd approach cleaning messy beauty product data is a big plus. We read every proposal carefully and respond quickly to strong candidates. Looking forward to working with you.
