Work Experience
Amazon
June 2022 - PresentSunnyvale, CA
Software Development Engineer 2
April 2025 - Present- Leading a cross-org effort to automate ticket investigation with AI agents. Live for 3 teams (30+ engineers) with 90% accuracy on holdout tickets, cutting root-cause time from 30-60 min to ~10 min across 1,200+ tickets a year.
- Built the agents' context from three layers: operational memory (past tickets clustered into reusable skills), a semantic code graph, and a knowledge layer of wikis, code reviews and design docs.
- Rewrote the seller contribution pipeline end to end to support LLM-based validation and enrichment, cutting CI/CD build times by 80%+.
- One of the core projects behind World Catalog, which powers Shop Direct: 250M listings for products sold on other sites, shown in Amazon search and Alexa.
- Launched 3 microservices with a plugin-based rules engine running 200+ rules for data validation and image enrichment.
Software Development Engineer 1
July 2023 - April 2025- Architected the Progressive Listing Experience, using LLMs to turn a seller's product URL into an Amazon listing.
- Built and maintained Amazon's catalog contribution ingestion pipeline.
SDE Intern, Item Pipeline
June 2022 - Sep 2022- Built a Code Analyzer that catches bugs and enforces coding standards before deployment.
- Rolled it out to the CI/CD pipelines of 8 teams, used by 100+ engineers.
- Built serverless microservices for the Item Pipeline with Java, TypeScript, Lambda and SNS.

Projects
Kiwi
July 2026 - Oct 2026- Built Kiwi's decentralized inference engine, which splits an LLM across a swarm of small machines and streams activations between them peer-to-peer over libp2p.
- Handles machines joining and dropping out with VRAM-aware layer assignment, heartbeat-based eviction, rerouting and paged KV cache management.
- Built decentralized LoRA fine-tuning on top of it as part of the team: 43% faster on 7 workers with instant recovery when a worker drops. Published at the NeurIPS 2026 CODEC-FM workshop.

Kiwi: Slicing Models and Reconciling Adapters in Fault-Tolerant, Decentralized LLM Fine-Tuning
poster
Harshil Patel, Parth Shah, Swayam Shah, Kunal Pai
NeurIPS 2026 Workshop: CODEC-FM
Introduces Kiwi, a fault-tolerant system for fine-tuning LLMs across swarms of memory-constrained devices. Kiwi shards a frozen base model across workers, trains LoRA adapters on each slice and merges them peer-to-peer, so no single device needs the full model. Layer slicing matches single-GPU held-out loss, replica averaging gives a 43% wall-clock speedup on a 7-worker testbed (39% over a simulated 75 ms WAN), and frozen base weights enable instant, zero-copy recovery when a worker fails mid-run.

NAAMSE: Evolutionary Security Evaluation Framework for Agents
paper
Parth Shah, Harshil Patel, Kunal Pai
arXiv / Berkeley RDI AgentX
Introduces NAAMSE, an evolutionary AI red-teaming framework and fuzzer designed to test LLM agents for security and utility. The framework utilizes genetic algorithms for real-time attack mutation, balancing Attack Success Rate (ASR) and False Positive Rate (FPR) to mitigate the 'over-blocking' problem in agentic systems. Recognized with 2nd place at the Berkeley RDI AgentX competition.

HASHIRU: Hierarchical Agent System for Hybrid Intelligent Resource Utilization
paper
Kunal Pai, Parth Shah, Harshil Patel
arXiv
Rapid Large Language Model (LLM) advancements are fueling autonomous Multi-Agent System (MAS) development. However, current frameworks often lack flexibility, resource awareness, model diversity, and autonomous tool creation. This paper introduces HASHIRU (Hierarchical Agent System for Hybrid Intelligent Resource Utilization), a novel MAS framework featuring a 'CEO' agent dynamically managing specialized 'employee' agents. Evaluations demonstrate HASHIRU's capabilities in complex reasoning, outperforming Gemini 2.0 Flash on benchmarks like GSM8K (96% vs. 61%) and JEEBench (80% vs. 68.3%).
