Full-Stack Web Developer (Next.js + Supabase) – Build SaaS App (ServiceLog)

???? Job Overview

We are building a web-based application called *ServiceLog, a platform that allows users to log service time on app or website and generate official tracking forms off the website.

Log service trips (date, hours, waters, etc.)
Automatically calculate qualifying service days
Generate a completed tracking form per vehicle
Download and print that form

Next.js (React, App Router, TypeScript)
Supabase (PostgreSQL + Auth + RLS)

You will build:

Phase 1 – App Structure
Next.js project setup

Phase 3 – Database + Core Features
Vessel management (CRUD)
Service log entry system
Data validation and structure

Phase 4 – Business Logic
