About me

I am a Software Engineer 2 at Apple with a strong background in Computer Science. I graduated from Thapar Institute of Engineering and Technology with a CGPA of 9.71, ranking in the top 0.5% and earning the TIET Merit Scholarship all four years. My work spans macOS tooling, 5G protocol testing, LLM-powered triage automation, and multi-agent systems for telecom software development.

Previously, I worked at PayPal and completed internships at Apple, Tata 1mg, Cisco, Licious, and YASH Technologies. I have also researched under Professor Dennis Shasha at NYU on the CustomNerd framework and with Dr. Parteek Kumar at Washington State University on agentic job matching.

Outside of work, I enjoy playing cricket, watching F1, going on treks, and working out at the gym. During college, I served as Vice Lead Ambassador of TICC and Placement Coordinator, building leadership and organizational skills alongside my technical work.

    Harsh worked with me as an intern for 2 months. He came fresh from college and was given a pretty technical, networking domain specific data science project as his goal. What he achieved in those two months was much more than what I had expected.
    We gave him the basics of the domain, some papers on what we wanted to achieve and unleashed him on our data. He was self motivated and inquisitive and figured out most of the stuff on his own. He was able to analyse our dataset and recommend what algorithms and datapoints made sense and what we should be able to use to model our models. I found him proficient in python and data science related technologies. He is very dedicated and has the tenacity to stick through the phase when things are not working and the data did give him many such issues.
    I am very happy with his work and even though our association was not very long his work will influence our design and products for some time. I wish him the very best in his future endeavours.
