Systems that reason.
Data that delivers.

I specialize in architecting stateful multi-agent workflows, hybrid local/cloud LLM pipelines, and structured data models. My goal is to build AI systems that are deterministic, cost-effective, and directly verifiable against real data.

How I Build Systems That Work in the Real World

A practical look at production AI: why monolithic prompts fail, where local quantization matters, and how data integrity drives every model.

PRINCIPLE 01

Stateful Workflows Over Monolithic Prompts

Single, giant prompts tend to drift, hallucinate details, and struggle with arithmetic. I break complex systems into stateful LangGraph agent nodes with validated Pydantic schemas. Heavy computations โ€” like spatial clustering, geo-routing, and math formulas โ€” run through deterministic Python solvers rather than burning AI tokens.

PRINCIPLE 02

Hybrid Latency & Cost-Effective Routing

Sending every request to a 70B cloud LLM leads to high latency and ballooning API bills. I engineer multi-tier routing architectures: sub-millisecond classifiers and local quantized models (Ollama) handle straightforward tasks instantly, reserving high-parameter cloud models strictly for complex reasoning and synthesis.

PRINCIPLE 03

Verifiable Grounding & Citation Traceability

In real-world applications, unverified AI outputs are a liability. Every RAG architecture I build guarantees source grounding โ€” linking responses to paragraph-level citation anchors, vector similarity scores, and strict schema validation so outputs can always be traced back to raw data.

Flagship Engineering Projects

Comprehensive systems engineered from scratch: complete state machines, custom mathematical scoring, real-time data pipelines, and production UI.

WanderAI โ€” AI Travel Planner

An autonomous multi-agent travel system built with LangGraph and Next.js 16. Resolves spatial disorientation and routing bugs in standard LLMs through K-means++ coordinate clustering, community sentiment analysis, and interactive timeline drag-and-drop editing.

Core Problem: Standard LLMs generate geographically chaotic routes (causing zig-zag transit), hallucinate closed attractions, and lack persistent state for iterative editing.
Architecture: 4-Agent LangGraph workflow (Intake, Ranker, Planner, Editor) with SQLite checkpoints and dynamic preference clarification.
Custom Engine: Log-normalized ranking formula balancing Reddit and travel blog sentiment against Google Places review volumes.
Real Data: K-means++ spatial POI clustering, live Open-Meteo forecasts, and a 4-tier zero-auth Wikipedia photography cascade.

AI Research OS

An end-to-end literature research platform combining arXiv paper discovery, layout-aware PDF parsing, vision models for figure captioning, and multi-agent literature survey synthesis.

Core Problem: Standard chat models shred complex multi-column academic papers, hallucinate mathematical formulas, and cannot reference visual figures or provide verifiable citations.
Parsing Pipeline: Docling layout analyzer with local Qwen2.5-VL vision models for extracting and captioning technical figures and tables.
Orchestration: 4-agent cyclic LangGraph team with dual router: local Ollama for background parsing and Groq 70B for real-time synthesis.
Traceability: Qdrant vector similarity search with Server-Sent Events (SSE) streaming and clickable paragraph-level citation anchors.
