Devspace

Devspace is a comprehensive IoT monitoring platform that enables students, hobbyists, and technicians to monitor ESP32/ESP8266 devices via a centralized web dashboard. It bridges the gap between hardware and accessible software with real-time visualization and smart alerting.

Frontend — Built with Next.js 14+ (App Router), TypeScript, Tailwind CSS, and ShadCN/UI. It features a responsive dashboard that handles real-time updates via WebSockets.

Backend — Developed using NestJS and TypeScript in a Turborepo monorepo. It leverages PostgreSQL with TimescaleDB for efficient time-series data storage and Redis for caching and job queues.

IoT Infrastructure — utilizing EMQX 5.8 as the high-performance MQTT Broker to handle massive device connectivity and message throughput.

I owned everything end-to-end:

• IoT Architecture — Designed the system to handle MQTT telemetry and real-time WebSocket push
• Fullsetsck Development — Built the NestJS backend and Next.js frontend apps
• Database Design — Implemented schema for users, devices, and time-series sensor data
• Monorepo Setup — Managed shared packages and multiple apps using Turborepo and pnpm
• Real-time Systems — Implemented live chart updates and instant alert notifications

• ⚡ Real-Time MQTT Integration — Connect ESP32/ESP8266 devices with ultra-low latency (<100ms).
• 📊 Time-Series Visualization — Efficiently store and visualize historical sensor data using TimescaleDB.
• 🔔 Smart Alert System — Configure threshold-based rules (GT, LT, EQ) to trigger email or webhook notifications.
• 📱 Interactive Dashboard — United control center for managing devices, sensors, and viewing live telemetry.
• 🔐 Secure Authentication — JWT-based auth with httpOnly cookies and Google OAuth integration.
