01 / About

Engineer-in-training with a hands-on bent.

I'm a Master's student in Electrical Engineering and Information Technology at Deggendorf Institute of Technology, specializing in Electronics and Telecommunication. My undergraduate work in Electronics & Communication Engineering (Saveetha Engineering College, GPA 87.2%) was built around embedded systems, microprocessors, VLSI design, and wireless sensor networks.

Day-to-day, I enjoy bridging hardware and software — wiring up sensors, writing the firmware to read them, and pushing the data somewhere useful. I'm currently deepening embedded software fundamentals through Prof. Vielberth's coursework and exploring how embedded/IoT systems intersect with cybersecurity, particularly SOC environments and cyber-range training.

Secure Industrial IoT Bridge (Modbus/TCP over SSH)

Problem

Retrofit legacy Industrial Control Systems: encapsulate plaintext Modbus/TCP SCADA traffic in an AES-encrypted SSH tunnel on an edge gateway — without breaking hard real-time latency budgets.

What I did

  • Designed a secure protocol bridge that wraps plaintext Modbus/TCP SCADA traffic in an AES-encrypted SSH tunnel for deployment on edge gateways.
  • Built an industrial simulation testbed in Python generating dynamic read/write operations (sensors and actuators) and validated HMAC data integrity via Wireshark deep packet inspection.
  • Engineered an automated benchmarking suite firing 1,000 unthrottled TCP requests to profile embedded constraints and confirm the crypto layer met hard real-time latency targets.
  • Measured a negligible 0.33 ms latency overhead from the cryptographic wrapper while cutting global CPU utilisation from 39.7% to 14.3% via efficient OS-level TCP stack management.

IoT-Based Driver Drowsiness & Alcohol Detection System

Problem

Build an automated vehicle safety system that detects driver fatigue and intoxication in real time, and shares live location with a remote dashboard.

What I did

  • Designed an Arduino-based safety system using a 780–1400 nm infrared sensor to track eye-blink frequency, detecting driver fatigue in under 1 second.
  • Engineered an intoxication-prevention mechanism with a 5V MQ-3 alcohol sensor (20 s preheat) that automatically cuts power to the DC motor and triggers an alarm on elevated ethanol ppm.
  • Interfaced an IoT Wi-Fi module with a NEO-6M GPS (5 Hz update rate, −162 dBm sensitivity) to continuously broadcast live vehicle coordinates to a cloud dashboard.

GSM-Based Remote Health Monitoring System

Problem

Continuously monitor critical patient vitals and alert medical personnel instantly when readings breach safe thresholds — without relying on hospital-grade networking.

What I did

  • Designed a real-time Arduino UNO system in C++ tracking three vitals: heart rate, ECG, and body temperature.
  • Integrated and calibrated MAX30100, AD8232, and DS18B20 sensors over I2C and 1-Wire with noise-cancelled biopotential acquisition.
  • Built an automated GSM-modem alert layer that SMSes registered clinicians the moment vitals exceed predefined thresholds.
  • Interfaced OLED and LCD displays for local graphical readouts within a 1.8–5 V low-power envelope.
  • Architected a scalability roadmap: cloud database for historical tracking and RFID-based patient authentication.

Hardware Project

High-Sensitivity Non-Contact Circuit Tester

Problem

Localize open circuits in live wiring without stripping insulation, using electromagnetic induction — with enough sensitivity to reliably separate live from dead zones at mains frequencies.

What I did

  • Developed a portable, non-contact electrical fault finder that senses stray EMF from live conductors and pinpoints breaks without physical contact.
  • Engineered the analog front-end as a 3-stage cascaded NPN Darlington array, amplifying nano-ampere antenna currents by ~1,000,000×.
  • Calibrated sensitivity to cleanly discriminate live vs. dead zones at 50/60 Hz mains, driving an instantaneous 3 V audible and visual alarm on fault detection.

Custom PCB Design & Prototyping (KiCad)

Problem

Take the non-contact tester from a fragile breadboard prototype to a compact, manufacturable, battery-powered handheld board.

What I did

  • Led schematic capture, footprint assignment, and full board layout in KiCad for the diagnostic hardware tool.
  • Designed a compact, ergonomically shaped 120 × 20 mm 2-layer board with a custom top-layer spiral trace antenna, deliberately restricting ground-plane shielding to maximize EMF pickup.
  • Transitioned from breadboard to a fully manufacturable PCB following standard DFM guidelines for through-hole (THT) components and battery-powered operation.
