KARTHIK BOINEPALLY
Senior AI Engineer
Bengaluru
Summary
Senior AI Engineer with 5+ years across backend engineering and applied GenAI, owning production-grade RAG and agentic systems in regulated legal and finance workflows. Led end-to-end development of a B2C/B2B GenAI legal research product serving ~700 daily users, architecting hybrid retrieval at scale (Milvus, TF-IDF + dense embeddings, RRF, cross-encoder reranking) to deliver high precision and low-latency performance. Strong in LLM reliability engineering (schema-safe outputs, rate-limit resilience, multi-model fallbacks, token optimization), OCR-driven document pipelines, and decision automation systems with human-in-the-loop controls. Proven technical leader who authors architecture docs, drives design reviews, mentors engineers, and ships measurable outcomes.

Work History
Consultant – Tax Tech Transformation
Ernst & Young LLP
03.2025 - Current
- Owned the end-to-end build of taxmann.ai, a production-grade GenAI legal research assistant (B2C & B2B), designing a layered Agentic RAG architecture (hybrid sparse+dense retrieval, cross-encoder reranking, context windowing) to reduce legal research time from hours to ~4 minutes for ~700 daily active users.
- Architected large-scale hybrid retrieval on Milvus (TF-IDF + BGE embeddings) with Reciprocal Rank Fusion, improving Top-3 precision from 65% → 92% over a ~4M-document corpus while maintaining p95 latency < 800ms under production load.
- Productionized multi-agent workflows using LangGraph (plan → retrieve → reason → validate) to deliver auditable, citation-backed responses at 94% decision accuracy, aligned with Big-4 legal and regulatory compliance requirements.
- Re-architected LLM inference and orchestration for production reliability, reducing per-query token usage from ~400K → ~100K tokens by implementing adaptive chunking, schema-validated outputs (Pydantic), exponential backoff for rate limits, and multi-model fallbacks, resulting in lower latency, stable responses, and predictable costs at scale.
- Designed and built a near-real-time Input Tax Credit (ITC) recommendation system, ingesting Excel-based line items, validating transactions via Kafka streams from internal ERP systems, and combining heuristics, embedding-based categorization, LLM confidence scoring, and LLM-as-Judge workflows with human-in-the-loop escalation; currently processes ~50K line items/day.
- Architected a production Legal Notice Submission system supporting Hindi and English, incorporating OCR-based document ingestion, RAG, and tool-calling workflows to extract verbatim citations and generate legally compliant submissions, significantly reducing manual drafting effort for legal teams.
- Led and mentored a team of 6 junior engineers (intern → full-time) by authoring architecture documents, driving design reviews, decomposing ambiguous problem statements into executable systems, and owning critical features end-to-end across multiple GenAI products.
- Reviewed PRs and guided execution across 3 concurrent GenAI projects, ensuring architectural consistency, production readiness, and high code quality through peer programming and hands-on ownership of complex components.
- Implemented persistent user context and long-term memory using Mem0 + Neo4j to enable persona-aware recommendations, and instrumented RAG pipelines with RAGAS-based evaluation for both development-time decisions and production monitoring (retrieval quality, drift, response performance).
- Built MCP-based tool-calling infrastructure to enable research-oriented agent workflows, coordinating multiple tools via structured schemas and remote MCP servers for scalable, modular reasoning pipelines.
