TechnoTex Pro — Industrial IoT Monitoring & Analytics Platform

Role: Full-Stack Engineer (Team of 3) · Duration: 2.5 months · Client: Surat-based textile manufacturer

Tech Stack: Node.js, Express, PostgreSQL, TimescaleDB, React 19, TypeScript, Electron, MQTT, BullMQ, Redis

Overview

Full-stack IoT monitoring platform for real-time loom machine tracking across multiple textile factories. The system ingests continuous machine telemetry via MQTT, computes shift-wise production analytics, and delivers automated PDF reports via WhatsApp — all running on a single 4-core / 16GB RAM server handling 1M+ daily machine logs.
