I am a Software Development Engineer II at Amazon with a strong foundation in computer science, backend systems, AI infrastructure, and research-grade engineering. I graduated from Thapar Institute of Engineering and Technology with a CGPA of 9.71, ranked in the top 0.5%, and earned the TIET Merit Scholarship across all four years.

My recent work spans Amazon Marketplace compliance intelligence, Apple production tooling, 5G/LTE/NR protocol automation, LLM-powered triage systems, multi-agent workflows, and open-source reliability work across AI platforms. I like work where the system has to be useful under real failure modes, not just impressive in a demo.

Looking ahead, I want to keep pushing on agentic systems that actually ship — evaluation harnesses that go beyond vibes, retrieval that is measurable, and infrastructure that makes failure visible. If it sits at the intersection of LLMs, systems, compliance, and reliability, I am probably already sketching it.

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.

My Interests

  • Platform engineering

    Building backend platforms and production tooling with Java, Coral, ECS Fargate, Amazon Bedrock, React, Spring Boot, Flask, and FastAPI, with emphasis on reliability, traceability, and clear service boundaries.

  • Data & cost modeling

    Working on Apache DataFusion, Parquet benchmarks, feature extraction, and explainable runtime models for serverless query planning and analytics systems.

  • Agentic AI systems

    Designing multi-agent workflows, RAG pipelines, semantic retrieval, and explanation panels for telecom automation, hiring support, and domain-specific assistants.

  • OSS backend reliability

    Quietly shipping reliability fixes into projects that the rest of the ecosystem depends on — RAG, agent runtimes, sandboxing, observability. I prefer code paths that fail loudly over code paths that fail quietly.

    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.
