## Work experience

Embedded Systems Intern at Addverb, Jan 2026 \- Present · 8 mos, Noida, • Designed and implemented a Kalman Filter to fuse differential\-drive encoder odometry with absolute barcode\-readerpose updates, eliminating systematic encoder bias and the discontinuous pose jumps that destabilised the velocity controller; profiled at 0\.70 µs predict step and 160 µs update step on the microcontroller architecture robot\. • Architected a dual\-bank OTA bootloader for the Zippy robot from scratch leveraging the STM32H7 SWAP BANK option\-byte for hardware\-backed rollback protection, using a single unified linker script, a three\-layer frame error\-detection protocol, and a metadata contract that makes the firmware\-update state observable at every boot\. Allowing wireless OTA FW, config and env updates on the robot from a server\. • Engineered a on\-device logging subsystem for microcontroller \- a 3,000\-instance circular ring buffer giving a 60\-second rolling telemetry window \- uploaded over to a TCP server using Lantronix xPico250’s MUX protocol for controlling server connections at runtime\. • Performed multiple RCAs and debugging for isolating issues, used strategic step by step approaches to isolate the problems and find the cause quickly\. Made detailed technical documentation and IROs for all the work done\.

IoT Intern at Climbax Entertainment Private Limited, May 2025 \- Aug 2025 · 4 mos, Gurugram, Haryana, India, • Engineered and optimized NFC & BLE\-based access management systems on ESP32\-S3, restructuring the codebase from scratch to achieve significant improvements in reliability and responsiveness through meticulous FreeRTOS task scheduling, efficient event handling, and custom BLE stack configurations\. • Developed an on\-device real\-time facial recognition system using ESP32\-S3, implementing efficient ML inference for rapid face detection and authentication\. This system prioritizes low\-latency performance and robust security for access control applications\. • Development of UHF RFID\-based boom barrier systems for automated vehicle access control, integrating robust reader communication protocols and implementing logic for secure and efficient entry/exit management\. • Implemented custom graphical user interfaces using LVGL for enhanced user interaction in access control systems, ensuring intuitive control and real\-time status display on embedded devices\.

Teaching Assistant at Shiv Nadar University, Aug 2024 \- Nov 2024 · 4 mos, On\-site, • Guided over 70 students in ECE202 Embedded Systems and Hardware, delivering hands\-on mentorship with STM32, 8051, 8081, and Arduino Uno projects\. • Proficiently used IDEs like Keil uVision, Arduino IDE, and STM32 Cube IDE, helping students master critical concepts in microcontroller programming, debugging, and hardware\-software integration\. • Enhanced students’ practical understanding, contributing to a 30 percent improvement in project completion rates and overall technical proficiency\.
