Hi there 👋 I'm Gauri Nigam

Typing SVG

Dual-hatted as an AI/ML Engineer & Systems Software Engineer.

I bridge the gap between complex research-backed models (RAG optimization, multi-agent orchestrations, real-time edge CV) and robust, high-throughput systems (production-grade memory debugging, high-performance database algorithms).

🧠 AI & Machine Learning

Frameworks & APIs: PyTorch, TensorFlow, LangChain, LangGraph, Hugging Face, YOLOv8, Gemini API, Anthropic API

Cloud & Infrastructure: AWS (SageMaker, EC2, S3, Lambda), Docker

AI/ML Stack

⚙️ Systems & Software Engineering

Languages: C++, Java, Node.js, SQL, TypeScript

Frameworks & Databases: Django, React, Redis, Microservices, PostgreSQL

Systems/Backend Stack

🚀 Featured Projects

Project Tech Stack Impact & Key Metrics
LLMEval Python, Gemini API, Anthropic API LLM-as-judge framework scoring RAG outputs on faithfulness, relevance, hallucination, coherence; validated against human ratings via Cohen's Kappa.
UrbanMind LangGraph, React, TypeScript Multi-agent system (intent classification, recommendation, rendering nodes, fallback/replanning logic) driving an interactive floor-plan UI.
GreenLight Go YOLOv8, OpenCV, C++ Real-time ambulance detection with 97.3% mAP @ 30 FPS, INT8-quantized for CPU-only edge deployment.

🔍 Systems Engineering Spotlight: OrganicOrbits Production Rescue

During my SDE Internship at OrganicOrbits, I worked on low-level systems profiling and optimization in a high-throughput microservices environment:

  • 🛠️ Production Memory Leak Resolution: Investigated and debugged a critical memory leak in a high-scale system handling 10,000+ events/minute with sub-100ms p95 latency requirements, stabilizing the production cluster.
  • ⚡ 40% Processing Time Reduction: Replaced a bottlenecked lookup algorithm with an optimized O(1) data structure, cutting data processing time by 40%.
  • 🧪 Pre-release Quality Safeguards: Penned comprehensive regression and integration tests that caught 3 critical pre-release bugs, preventing potential downtime.

🌐 Open Source & Competitive Programming

  • Haystack (Deepset) (21k+ ⭐): Merged a PR fixing an embedding precision bug.
  • traceAI: Merged a PR fixing a critical span-overwrite bug corrupting distributed trace data.
  • Codeforces: Expert (Peak Rating: 1769, top 2% globally).
  • CodeChef: 3-Star (Peak Rating: 1749, top 0.06% worldwide).
  • TVS Credit EPIC Hackathon: Ranked 2nd / 62,000+ teams.
  • ChurnZero Hackathon (IIT Kharagpur): Finalist (among 1,300+ teams).
