About

Internship at ActiveVM where they tackled large-scale Spring Boot 2→3/library migrations across hundreds of downstream products by combining OpenRewrite (AST-based recipes) with an LLM/RAG-based classifier that routed risky files to human experts. Reported ~70% reduction in manual effort and 90%+ accuracy after testing across multiple branches and cutovers; also built a CTR-driven book recommendation capstone showcased at the Google office in Cambridge.

Key Strengths

• Owned end-to-end automation for large-scale library migration across hundreds of dependent products
• Designed hybrid AI + OpenRewrite pipeline with human-in-the-loop routing to reduce manual effort ~70%
• Implemented RAG/embeddings-based decision system using documented migration rules as a knowledge source
• Built practical guardrails using confidence thresholds to prevent risky automated rewrites
• Delivered high reported effectiveness in production testing (90%+ accuracy across multiple branches/cutovers)
