Smart Spray

Overview

Smart Spray is a dashboard platform that tracks chemical usage in lawn care applications through proprietary hardware integration. I worked on both the initial MVP development and led a comprehensive technical modernization effort.

What I Built

MVP Development

Built the initial product to get the platform to market:

• •Dashboard for tracking chemical applications across lawn care jobs
• •Integration layer for proprietary hardware devices
• •Real-time data sync from field equipment
• •Reporting system for compliance and usage analytics

The MVP was built with React, Node.js, and JavaScript to validate the concept quickly.

Platform Modernization

Led a large-scale refactoring to improve scalability and developer experience:

Frontend Migration

• •Migrated from React SPA to Next.js with App Router
• •Implemented server-side rendering for better performance
• •Restructured components for server/client optimization

Backend Refactor

• •Rebuilt Node.js services using NestJS framework
• •Added dependency injection and modular architecture
• •Improved API structure and error handling

TypeScript Migration

• •Converted entire codebase from JavaScript to TypeScript
• •Added type safety across frontend and backend
• •Improved code maintainability and caught bugs at compile time

Impact

• •Successfully delivered MVP and validated product-market fit
• •Improved development velocity through better code structure
• •Enhanced type safety reduced runtime errors
• •Server-side rendering improved initial page load performance
• •Modular architecture enabled easier feature development
