IoT-Based Intelligent Medication Management & Vitals Tracking
• Designed a connected monitoring system integrating sensor data acquisition, remote vital-sign reporting, and power-
efficient embedded hardware.
• Calibrated and tested sensor arrays for reliable measurements and developed the hardware-software path from physical
sensing to digital monitoring.
Relevant technologies: embedded sensors, real-time data acquisition, remote monitoring, IoT integration
Smart Electrical Phase Selector
• Designed and prototyped an automated phase-selection system to detect supply conditions and switch electrical phases,
reducing downtime caused by phase failure.
• Combined sensing, control logic, switching, and electronics integration in a power-management application relevant to
connected energy systems.
Focus: power monitoring/control, automation, embedded systems
IoT Monitoring & Remote-Control Interfaces
• Built web/mobile dashboards for visualizing IoT data and controlling connected systems using React, Next.js, and React
Native.
• Integrated device and backend data flows through APIs, supporting remote logging, monitoring, and control of
sensor/actuator systems.
Stack: React, Next.js, React Native, REST APIs, IoT device integration
E-Commerce Platform Modernization | Full-Stack Engineering
• Solely architected and rebuilt two live commercial e-commerce platforms from WordPress into React + NestJS applications
backed by PostgreSQL.
