About

I started out studying electronics at IIT (BHU), moved into camera software at Samsung, and later dug into research on time series pattern mining at the University of Waterloo. Now I build Networking OS software at Cisco. It’s been a pretty varied path, and I’ve enjoyed getting to know each area from the inside.

Work Experience

Cisco

Software Engineer III

Networking, Systems Software, C++, Python

  • Build production software for networking and systems products in Cisco’s Ottawa engineering organization.
  • Apply C++, Python, operating-systems, and algorithm-design experience to performance-focused engineering work.
  • Collaborate with cross-functional engineers to develop, test, and deliver reliable software.

University of Waterloo

Teaching Assistant

Mentored students in operating systems, RTOS, C/C++, debugging, and performance analysis across SE 350, ECE 350, and ECE 307.

University of Waterloo

Graduate Research Student

Time-Series Analysis, STUMPY, MiniZinc, Constraint Optimization

  • Developed a thesis method for mining recurrent time-series patterns using matrix profiles and constraint optimization.
  • Published and presented the resulting research at IEEE/ACIS SERA 2025.

Samsung R&D

Software Engineer, Camera Team

C++, Python, OpenCV, Camera HAL, OIS, Image Processing

  • Developed camera algorithms for flagship Galaxy devices, reducing motion blur by 30% and improving low-light performance by 20%.
  • Integrated Android 12 and 13 camera firmware updates across Galaxy S21 and S22 devices.
  • Filed 4 patents and co-authored research publications on camera systems and image enhancement.

Samsung R&D

Software Engineer Intern
