About

Built an LLM multi-agent “ingredient safety” analyzer for cosmetics that cuts consumer research time from ~20+ minutes to minutes, using LangGraph orchestration, hybrid retrieval (Qdrant + Tavily), and safety-focused critic validation (false rejections reduced ~30%→~8%). Also has research-internship experience building computer-vision pipelines to classify emerald color/clarity by translating gem-expert heuristics into quantitative model features.

Key Strengths

  • Built and deployed a multi-agent cosmetic ingredient safety analyzer with personalized recommendations
  • Designed agent workflow with supervisor/research/analysis/critic roles and conditional routing in LangGraph
  • Solved JS-rendered scraping blockers by adding rate limiting/retries and identifying need for Selenium
  • Improved critic agent performance by refocusing validation on safety-critical issues (reduced false rejections from ~30% to ~8%)
  • Pragmatic model selection based on cost/latency constraints (Gemini 2.0 Flash for ~20–30s responses)
  • Implemented hybrid retrieval with Qdrant semantic search plus web-search fallback using similarity threshold (<0.7)
  • Established reliability approach with measurable criteria (completeness, allergen detection as non-negotiable, latency) and iterative real-case testing
  • Collaborated with non-technical domain experts to convert qualitative gemstone grading into quantitative CV classification criteria

Mid-Level Software Engineer specializing in Generative AI and RAG systems

Remote, USA5y exp
MetaUniversity of North Carolina at Charlotte

“Built a production RAG-based natural-language-to-SQL system at Global Atlantic to replace slow, expensive manual analytics ticket workflows, focusing heavily on retrieval quality and measurable evaluation (200-question ground-truth set; recall@5 improved 0.65→0.78 via semantic chunking). Also built a custom MCP-style agent orchestrator for a personal project (arxiv-ai) to improve flexibility and Langfuse-aligned observability, and has hands-on experience with LangGraph, CrewAI, and n8n.”
