Senior Software Engineer / Manager

Bristol Myers Squibb

Architecting enterprise AI platforms, distributed backend systems, and digital manufacturing solutions supporting global pharmaceutical operations — Enterprise MES.

• Architected a production-grade pharmaceutical Recipe Authoring Agentic AI platform using LangGraph, Amazon Bedrock, RAG, MCP/tool calling, Human-in-the-Loop workflows, and LangSmith-based observability — reducing recipe-authoring effort from 4 months to 10 days.
• Architected MCP-based semantic retrieval using AWS Aurora PostgreSQL/pgvector, enabling AI agents to discover and retrieve relevant enterprise configurations through vector similarity search.
• Built an ETL pipeline to vectorize enterprise configurations and implemented a resilient three-tier retrieval strategy across site-specific and global knowledge bases.
• Eliminated 12,000+ engineering hours annually by designing a distributed Manufacturing Validation Platform executing automated regression and load testing across multiple MES environments.
• Led architecture and technical design for enterprise AI platforms, partnering with business, site stakeholders, and senior leadership; established a continuous product feedback loop and presented architectural trade-offs and demos to drive rapid product evolution.
• Enabled natural-language analytics across 30+ enterprise manufacturing databases via a production-grade Text-to-SQL AI platform using semantic retrieval, vector databases, SQL validation, execution guardrails, and LLM-generated summaries.
• Reduced regulated software validation effort from hours to minutes (40% improvement) with an AI-powered test script generation platform leveraging historical validation assets, RAG, and few-shot prompting.
• Reduced critical API response time by 78% (32s → 7s) through SQL query optimization, indexing redesign, stored procedure tuning, and execution plan analysis.
• Modernized a proprietary enterprise desktop application by reverse-engineering SQL execution patterns and building scalable Node.js REST APIs enabling full workflow automation.
• Collaborated with the Chief Digital Architect to review enterprise architecture, validate technical designs, and align AI platform implementations with organizational engineering standards.
