ABOUT ME

I'm an Embedded Systems Engineer with a background in Electronics & Communication Engineering, passionate about building things at the intersection of hardware and software. From programming industrial PLCs to prototyping on Raspberry Pi and STM32 ARM Cortex — I like working close to the metal.

At Vizag Steel Plant (RINL), I automated furnace billet-handling logic eliminating manual handoffs with zero faults. My independent project — Unicard — consolidates 4 vehicle documents into a single RFID smart card scannable in under 2 seconds.

Quantum-certified through MeitY's DST-NQM programme. Actively seeking an Embedded Systems Engineer role where I can contribute from day one — working with ARM Cortex, RTOS, and industrial-grade embedded platforms.

EXPERIENCE

Intern — Microprocessors & PLCs
Vizag Steel Plant (RINL) · Visakhapatnam
JUN 2024 — AUG 2024
  • Programmed PLC ladder logic automating furnace billet-handling across 6 sensors, eliminating 3 manual handoff steps and achieving zero faults across 3 control cycle validations.
  • Validated hardware-software integration under continuous production load and documented control architecture for 4 plant systems using 8085/8086 microprocessors.
Intern — Embedded Systems & IoT
Blackbuck Engineers Pvt. Ltd. · Hyderabad
JAN 2025 — MAR 2025 · 240 HRS
  • Completed a rigorous 240-hour long-term internship on Embedded Systems & IoT, organized by Blackbuck Engineers in association with APSCHE (Andhra Pradesh State Council of Higher Education) — covering ARM Cortex-M architecture, peripheral configuration, sensor interfacing, serial communication protocols (UART, SPI, I2C), and embedded C firmware development under structured coding standards.
  • Developed and validated embedded prototypes using ESP32 and Arduino platforms — implementing sensor data acquisition pipelines, interrupt-driven real-time firmware, and wired communication between MCUs and peripheral modules. Applied hardware debugging techniques with register-level peripheral configuration, directly reinforcing skills demonstrated in portfolio projects: RFID Secure (SPI + EEPROM security), Biogas Monitor (MQ-series sensor interfacing), and Accident Detection System (multi-module I2C/UART integration).
Intern — Arduino, Raspberry Pi & Radar Sensors
Sri Shasha Prayathi Technologies · NITK-STEP, Mangalore
MAY 2023 — JUN 2023 · 4 WEEKS
  • Completed an online internship on Programming with Arduino Uno and Raspberry Pi with Radar Sensors for IoT Applications, certified by Sri Shasha Prayathi Technologies at NITK-STEP, Surathkal — one of India's premier technology business incubators hosted at NIT Karnataka.
  • Programmed Arduino Uno and Raspberry Pi for real-time sensor integration — implemented radar-based distance measurement and object detection, interfaced sensors over GPIO and serial communication, and built end-to-end IoT application prototypes combining sensor data acquisition with embedded processing. These skills directly transferred to subsequent projects: Smart Biogas Monitor (ESP32 + MQ-series gas sensors) and Accident Detection System (ESP32 + ADXL335 accelerometer + GPS + GSM).
