Software Engineer with 4+ years of experience building high-throughput distributed systems. At Walmart Global Tech, shipped campaign management and reporting infrastructure processing 100M+ events/day with sub-15-minute SLAs and 200K+ external API requests/day. Currently finishing an MS in Computer Science at UIC (GPA 4.0) and applying those systems instincts to production AI — RAG pipelines, agentic workflows, and LLM inference.

Backend & Distributed Systems

• Event-driven pipelines, low-latency APIs, bulk processing, and observability
• Java, Scala, Spring Boot, Akka, Kafka
• Latency and reliability are constraints, not afterthoughts

AI Systems (Production, Not Demos)

• Agentic RAG with LangGraph, vector search, guardrails, and human-in-the-loop escalation
• LLM-based confidence scoring and authenticated multi-department access

Data Infrastructure

• ETL pipelines, Spark/Hadoop at scale, MS SQL Server, PostgreSQL
• Owned pipelines from ingestion through analytical delivery

Walmart Global Tech — Software Engineer II → III (Jul 2021 – Jun 2024)

• 100M+ advertising events/day through async Azure Queue pipeline, <15 min SLA
• 50M+ state changes/month in persistent campaign history system
• Bulk APIs cutting partner API calls by 70%; 200K+ external requests/day under governance
• 93% reduction in manual keyword reviews via Kafka event-driven automation
• 40% reduction in MTTR via Prometheus/Grafana observability
• Led PR standards for 8-engineer team; reduced escaped production defects by 30%

UIC Technology Solutions — Graduate Assistant (Oct 2024 – Present)

• Agentic RAG chatbot serving 12+ university departments (LangGraph, FastAPI, vector search)
• 87% improvement in response accuracy via query reformulation and optimized retrieval
• Guardrails with LLM-based confidence scoring and automated escalation to human support

Distributed LLM Training & Inference System · Scala · Spark · DL4J · gRPC · AWS

• Hadoop/Spark pipeline: ingestion → tokenization → embeddings → semantic similarity
• gRPC inference layer routing across local Ollama and AWS Bedrock with multi-turn memory
• Deployed as containerized microservices on EC2 with Lambda serverless routing

RhythPic — AI Music Visualization Platform · React · Node.js · MongoDB · Genius API

• Full-stack app generating AI visuals synchronized to time-coded lyrics
• MongoDB caching reduced external API calls by 60%
• Real-time lyric sync and playback queue via React Context API
