Lead Developer (or Team) for Nonprofit Mobile-Responsive Web Platform (React/Supabase) - 45 Day Sprint

Job ID: 40148173

Budget: $2,500 – $4,126 USD

We are a nonprofit organization that connects volunteers with elderly and disabled homeowners who need help with lawn care. We operate on a "labor of love" model and are making a significant investment to automate our backend operations.

We are looking for a Technical Project Manager + Developer (or a small, tight-knit agency) to build our new volunteer management web platform. We have an existing WordPress website that serves as our public-facing marketing and intake site, but we are building a custom mobile-responsive web application (using Lovable.app & Supabase) to handle the complex logistics of volunteering

Note: This is NOT a native iOS/Android app project. This is a mobile-first React web application that must work flawlessly on mobile browsers.

The Context:

We are not starting from zero. We have a comprehensive 20-page "Master Technical Blueprint" (Technical Spec) that defines every table, user flow, and SMS template.

The Tech: We have chosen the Lovable.app + Supabase stack to move fast. You must be comfortable working in this environment.

Timeline: This is a 45-day sprint. We must be "Code Complete" by February 28th for our Spring Launch.

Current Site: Attached Screenshot. (See attached screenshots for the new platform vision).

The Tech Stack
Frontend: Lovable.app (React/Vite) - Mobile-First Design.

Backend/Database: Supabase (PostgreSQL, Auth, Edge Functions, Row Level Security).

Communication: Email & Twilio (SMS/Voice Masking).

Maps: OpenStreetMap / Leaflet.

Scope of Work
You will be executing a strict "Definition of Done" checklist provided in our specs.
The build is broken into 4 core modules:

1. Core Automation (The "Uber" for Lawn Care)

Migrate our "Wishlist" of features into a functional web app.

Rebuild existing Volunteer Dashboard with geolocation (Job Feed).

Implement a "3-Stage Commitment Flow" (Address is hidden until the volunteer commits).

2. The "Community" Layer (New Features)

Group Events: A module for corporate/civic groups to "Pledge a Service Day" (B2B2C model).

Volunteer Rosters: A rotation system where multiple volunteers support one homeowner (preventing burnout).

Privacy Guard: Strict logic to ensure addresses are never shown on public feeds.

3. Grant Compliance & Admin

Equipment Tracking: An improved system (to what we have already) to track usage of equipment used.

Impact Reporting: Auto-generate reports on "Fines Saved" and "Hours Volunteered" for our auditors.

4. Immediate Fixes

We have a minor login/auth issue on the current build that needs an immediate fix to start the engagement.

Ideal Candidate Profile
Mobile-Responsive Expert: You know how to make complex forms feel simple on a smartphone browser.

You Speak "Grant": You understand that if the "Impact Report" doesn't work, we lose funding.

You are a Builder: You are happy to use Lovable.app to accelerate the UI, but you know how to write custom Supabase Edge Functions when the low-code tool hits its limit.

Budget & Terms
Budget: This is a fixed-price contract funded by a grant. We have a set budget and a set scope.

Timeline: Kickoff immediately. Delivery by Feb 28th.

Status: We are a 501(c)(3) nonprofit.

How to Apply (Please Read Carefully)
We will not respond to generic copy-paste proposals. To be considered, please reply with:

The "Password": Start your proposal with the phrase "I am ready to Mow."

Your Stack Experience: Confirm your specific experience with Supabase Row Level Security (RLS) and Google API, Twilio API.

Approach: Briefly explain how you would handle "Group Event" privacy—specifically, how you ensure a homeowner's address is visible to the group lead but hidden from the public feed.

Upon selection of a shortlist, we will share the full "Master Technical Blueprint" for a final accurate quote.
