A multinational industrial manufacturer in Chennai faced a unique challenge: converting AutoCAD designs into instruction codes compatible with a newly imported CNC machine from Germany. Tasked with this project, I analyzed the CNC machine's operations and optimized its instruction files to minimize tool changes and machine movements. Using the traveling salesman algorithm, I calculated the most efficient paths for tool usage and transitions, ultimately generating precise instruction files for panel cutting. The solution underwent a live UAT demonstration on the shop floor, witnessed by hundreds of employees. This complex, high-stakes problem, with minimal room for error, remains one of the most rewarding achievements of my career.

I led the operations module of an ERP system for a tile manufacturing company, focusing on predicting delivery dates based on complex variables. This involved analyzing raw material availability (using dynamic bills of materials), workforce capacity, and production lead times for various tile types. By coding precise logic for these factors, the module enabled accurate predictive analytics, significantly enhancing the efficiency of the sales and production teams. This transformative solution streamlined operations and became a game-changer for the company.

I developed the air reservation module for a travel website during the early days of online booking. Using C++, I built dynamic libraries to communicate with Sabre travel systems via UDP, implementing commands for availability queries and bookings while ensuring persistent connections. This project offered invaluable experience in tackling complex systems and real-world challenges with innovative solutions.

Designed and implemented a full home automation system on the Home Assistant platform, integrating Zigbee, Z-Wave, Matter, and Wi-Fi IoT solutions. Automated all lights, switches, and security using sensors and cameras. Developed custom scripts and modules to enhance functionality and built DIY hardware solutions, including LED strips, a plant water monitor, a water meter reader, and a radon detector alert.
