I build backend-focused full-stack projects that move from requirements to production. At Autowin, I delivered 8 factory client projects as the sole developer, owning the full cycle and keeping everything consistent with shared modules and a standardized deployment process.

I built a factory IoT system that pulls 300 data points in real time from 20 production machines over Modbus and MQTT, refreshing as fast as every 30 seconds and writing to GCP Firestore. I also created a React + TypeScript monitoring dashboard with interactive Chart.js visuals so floor staff can view all 20 machines on one screen.

I’ve focused on automation and reliability: production reports cut daily manual work from about 1.5 hours to about 3 minutes, and AI anomaly detection shifted equipment fault handling from manual checks to instant alerts. I’ve also built Google Sheets automation scripts using the Google Sheets API and webhooks to save clients estimated 5 hours of manual work per week.

In Web3, I built and deployed a full-stack dApp where two players stake ETH and settle via a Chainlink oracle, backed by a Solidity 0.8.24 contract and 22 Foundry tests with security checks. I’m comfortable building event-driven frontends with Next.js, React, TypeScript, wagmi/viem, and using TDD as I ship.
