Full Stack developer & IOT devs
I’m John Orland Sudoy, a developer with experience in React JS, Node JS, Python (FastAPI), C#, and C++. I specialize in building web applications and integrating software with hardware through IoT and Arduino projects. I also work on robotics, creating solutions that connect technology with real-world use. My approach is practical and client-focused—I enjoy turning ideas into working systems that are reliable, scalable, and easy to use. Whether it’s a modern web platform, an IoT prototype, or a robotics project, I aim to deliver results that help clients achieve their goals.
Cyber Security / Industrial Engineer
Proposes solutions to minimize delays, errors, setbacks and freely shares and seeks useful knowledge to complete work.
Project Showcase

Simulation of a smart waste station: classification, servo routing, full-bin notifications, and thermal analysis for the biodegradable compartment.
Tech Stack

ESP32 water-level and leak detection with ultrasonic sensing, firmware in PlatformIO/C++, and a dashboard for alerts — built for real-time monitoring instead of periodic manual checks.
Hardware
Firmware

Solar/inverter-focused battery health monitor on ESP32-S3 with current sensing, firmware in C++, and a React + Supabase view for charge, load, and health trends.
Hardware
Firmware

Autonomous farm robots with ESP32-C6, soil sensing (moisture, pH, nutrients), and a real-time controller so field checks are consistent without extra labor.
Hardware

Laundry water-recycling system on Arduino Mega. Turbidity, pH, and temperature sensors drive filtration so soapy water can be reused safely.
Hardware

Smart aquaponics pod: lettuce above, tilapia below, automated feeding and ultrasonic water-level control on Arduino Uno for balanced plant and fish conditions.
Hardware

NFC digital business-card platform: tap to share contact details, socials, and links without reprinting cards. React, Node.js, Tailwind, and Supabase.
Tech Stack

Bus operations software with live tracking, staff portal for drivers/conductors, and a passenger portal for tickets and payments.
