Currently working on Embedded Systems development using a CrowPanel 7-inch ESP32-S3 microcontroller-based LCD touch panel, implementing dynamic QR code display, scrolling advertisement display, and self-ordering kiosk functionality. Also developed a multi-user cloud-based quotation management system with RBAC, created Chrome extensions to automate tasks, built Selenium-based automation scripts, and conducted research in object detection (YOLO) and a Face Recognition–based Attendance System with backend APIs and data management.

Managed a data platform with 350M+ records, achieving ~90% query-time reduction through SQL optimization, indexing, and technology selection (MySQL and DuckDB). Built ETL pipelines integrating Salesforce, Ontraport, and WooCommerce for centralized reporting. Designed and delivered 10+ custom ERP/CRM desktop/LAN applications. Built a Java-based Android app for field agents with offline SQLite synchronization and socket programming.
