PRAVESH is an IoT-driven RFID gatekeeper that revolutionizes campus access with seamless, secure, and paperless entry—delivering real-time logs and instant automated approvals.

This project presents the design and concept of a 10 cubic meter stainless steel storage tank made from grade 304L, intended for industrial and smart fluid management applications. The tank has been carefully designed to ensure durability, corrosion resistance, and suitability for integration with IoT monitoring systems. The tank structure includes a main cylindrical shell (virole), two dished heads (fonds), support cradles (berceaux), a lid (couvercle), a valve (vanne), and a custom nozzle (piquage) for input/output. It is designed to withstand varying fluid pressures and can be used in a variety of industries such as food processing, water treatment, chemical manufacturing, and agricultural storage. The CAD model has been developed using SolidWorks, employing sheet metal features and realistic welding simulations.

This project aims to accelerate the process of identifying soil density values from the subgrade, subbase, and base course layers by integrating vibration, speed, and acceleration sensors connected to an Arduino Mega 2560 microcontroller. The data generated enables real-time monitoring and adjustment during the compaction process in accordance with SNI (Indonesian National Standard) 1738-2011.

A basic suspension system was designed for a simple land vehicle, focusing only on essential functionality and minimal comfort. This is an experimental project. As someone who has previously worked on designs such as self check-in kiosks, this project represents one of my first simple attempts related to vehicle systems. Note: The part files could not be uploaded to the system, but you can access them via the following link: ???? https://grabcad.com/library/car-suspension-system01-1 Video: The step-by-step assembly of the suspension system can be followed in the video provided. You can assemble the parts in the same order shown in the video.

This system offers an automated attendance tracking solution by combining RFID technology with IoT capabilities—specifically, NodeMCU (ESP8266) for connectivity and Google Sheets for cloud-based record keeping. It enables real-time capture and tracking of attendance data

I was part of a team that built an automated marble sorting and lifting machine with three unique mechanisms. My specific role was to architect and execute the entire electronic nervous system. I solo-designed and fabricated a custom PCB that integrated dual microcontrollers, motor drivers, Bluetooth, and robust power regulation. My parallel-circuit design guaranteed no single component failure could take down the whole system. I delivered a professional, reliable control hub that brought our team's mechanical designs to life
