About Me

Coding

  • SDE II at Amazon, working on large-scale compliance infrastructure
  • Previously SWE II at Apple: macOS tooling, 5G protocol testing, LLM triage automation - 80% adoption on internal tools, 40% faster incident resolution, $720K annual savings
  • Earlier: PayPal full-time; internships at Apple, Tata 1mg, Cisco, Licious, YASH Technologies
  • Open-source engineering across RAG and agent infra: retrieval correctness, agent runtime hardening, plugin triggers, sandbox safety, observability, protocol tooling - mostly in RAGFlow, Dify, Langfuse, NDN, Infinity, CustomNerd
  • Research with NYU, WSU, UCLA, UBC, Edinburgh - CustomNerd accepted at MDPI Electronics, JobMatch in preparation for JAAMAS
  • B.E. CSE, Thapar Institute - CGPA 9.71, top 0.5% merit scholarship
  • 1,723 LeetCode (568 easy / 916 medium / 239 hard, rating ~1,693) · 450+ Topmate sessions at 4.3/5

Where I'm Heading

Open-source contributions and research directions I'm pushing into over the next 6–12 months.

Open Source Upstream Projects Repositories

Open Source

Track Direction
RAG infra infiniflow/ragflow — agent inputs, DeepDoc parsing, clustering, and retrieval-quality edge cases.
Agent frameworks langgenius/dify, dify-sandbox, and dify-official-plugins — sandboxing, plugin auth, and model-provider plumbing.
LLM observability langfuse/langfuse and the neatlogs SDKs — endpoint validation, transport replay guards, SDK init consistency, span routing, and provider isolation. Interested in OTel-native tracing, evals, and feedback loops.
Vector & AI-native DBs qdrant-client, infinity, and ragas — evaluation harnesses for CustomNerd outputs.
Protocols & mobility named-data/ndnd security/CRL work · background in 5G protocol testing.

Research

  • CustomNerd — accepted at MDPI Electronics
  • JobMatch — in preparation for JAAMAS
  • Odyssey — cost-model work with the University of Edinburgh
  • ScientficPerplexity — with UBC

Focused on RAG systems, agent frameworks, observability, protocol tooling, and practical reliability work in open-source codebases.
