I build production AI systems — LLM pipelines, RAG architectures, and agentic workflows — and ship them inside real products used by real businesses.

As Team Lead of Product and Senior Software Engineer at Codexpert, Inc., I lead EasyCommerce: an AI-powered WordPress eCommerce platform integrating OpenAI, Anthropic Claude, Gemini, and DeepSeek for automated product content generation, smart pricing logic, fraud detection, and predictive analytics. Custom database architecture delivering 3–5× faster performance than WooCommerce. 35% conversion uplift in beta.

4+ years of full-stack production engineering. 8 plugins independently authored on WordPress.org. Code contributed to products serving 60,000+ active businesses. WordPress Core Contributor since 2021.

JobPulse RAG AI-powered job discovery platform with RAG-grounded cover letter generation. Multi-source pipeline across 12 sources in 3 tiers: search engines (SerpAPI, JSearch), free boards (RemoteOK, WWR, Remotive, HN), and ATS public APIs (Greenhouse, Lever, Ashby, Workable, SmartRecruiters). Resume embedding via text-embedding-3-large + pgvector cosine retrieval — all cover letters grounded in actual resume content via Claude Sonnet. Composite scoring: semantic + BM25 + salary + geo. Python FastAPI pgvector Redis Celery OpenAI Anthropic React 18 Tailwind Docker

codebase-research-agent Tool-using ReAct AI agent that researches codebases through multi-step reasoning over a hybrid retrieval substrate. Agent loop wraps semantic search, AST navigation, symbol lookup, grep, and git blame as callable tools via OpenAI function calling and Anthropic tool use — iterates think → act → observe until grounded. Privacy-first dual mode: cloud (OpenAI + Claude Sonnet) or fully local (Ollama + deepseek-coder). Exposed as a Claude Code MCP server with streaming SSE and file/line citations. Python FastAPI tree-sitter pgvector BM25 Ollama OpenAI Anthropic MCP SDK Docker

Specialized Technical Assistant (RAG) Domain-specific AI assistant pipeline grounded in your own documentation. Python-based RAG with LangChain, pgvector, PostgreSQL, Claude, and Sentence Transformers. Python LangChain pgvector PostgreSQL Claude Sentence Transformers
