Engineeringintelligenceinto production.

I'm Raju — an AI/ML Engineer with over 6 years across silicon, payments, and retail at scale. I build production LLM systems, agentic AI workflows, MCP servers, and RAG pipelines — and the evaluation and MLOps machinery that keeps them honest.

01 · Positioning

Building AI systems
that are actually deployed.

Frontier models are easy to demo. Getting them past compliance, into production, and onto the critical path — that's the work I care about.

Philosophy

LLMs are a component.
MLOps is the product.

My work centers on the unglamorous layer between a model and a user — retrieval, evaluation, observability, safety rails, and deployment. I architect Model Context Protocol servers, LangGraph multi-agent workflows, and fine-tuned RAG pipelines that survive contact with auditors.

Arm MCP Server & Cloud Migration Agents

Architected the Arm MCP Server and the agentic retrieval stack behind it — letting AI agents inside IDEs discover and chain cloud migration workflows that move production workloads from x86 to Arm across AWS Graviton, Google Axion and Azure Cobalt 100.

  • Architected the Arm MCP Server in Python + FastMCP so IDE agents discover and chain migration workflows — developer onboarding time down 60%.
  • Standardized MCP + JSON-RPC tool calling across GitHub Copilot, Claude Code, Kiro CLI and Gemini CLI, compressing migration analysis and refactoring for Graviton, Axion and Cobalt 100.
  • Built a containerized Milvus RAG knowledge base over Arm docs with LlamaIndex orchestration and LangSmith tracing — LLM code hallucinations down 85% at lower prompt-token cost.
  • Curated 12K instruction pairs from Arm docs and Neo4j graph triples and fine-tuned Llama 3 8B via LoRA (rank 16) — domain accuracy 52% → 70% on a held-out 200-query benchmark.
  • Benchmarked BGE-large, E5-large and text-embedding-3, then fine-tuned the selected bi-encoder with contrastive learning on hard negatives mined from failed retrievals — Recall@5 +15 points over baseline.
  • Added Cohere Rerank via Amazon Bedrock as a second stage over hybrid BM25 + dense retrieval, tuning chunk size and overlap for code-heavy docs — higher top-3 precision and fewer tokens per query for ~100ms added latency.
  • Orchestrated multi-agent workflows on GPT-5 and Claude via Bedrock with LangChain + LangGraph, served open-source models on vLLM for low-latency inference, and delegated agent roles through CrewAI and AutoGen.
  • Built Tesseract OCR pipelines to fold multi-format internal docs into the vector store, with Python jobs regenerating Milvus embeddings on every documentation update at zero user-facing downtime.
  • Embedded AWS Copilot CLI and Terraform into the retrieval layer behind guardrails, policy models and audit trails so autonomous agents emit only least-privilege IAM infrastructure.
  • LLVM-MCA accelerated assembly-level benchmarking ; sysreport and Arm Performix exposed as callable AI functions replaced 6 hours of manual telemetry with real-time profiling.
  • Shipped offline/online eval harnesses plus a CI pipeline running regression tests and prompt-version A/B comparisons before every release, with production observability on EKS and ECS tracking SLOs, agent health and telemetry.

FraudSight for Worldpay

Real-time fraud detection and risk scoring across billions of payment transactions — end-to-end ML from large-scale feature engineering to sub-100ms inference, under PCI DSS, PSD2 SCA and 3-D Secure constraints.

  • Engineered the FraudSight real-time risk scoring engine (Adaptive Behavioral Analytics, scikit-learn, ensemble XGBoost) on billions of transactions — fraud chargebacks cut by up to 95%.
  • Designed feature engineering pipelines on Spark, PySpark and Databricks Lakehouse over 40B+ annual transactions, feeding Snowflake for identity profiling and model training.
  • Built RNN Deep Behavioral Networks (TensorFlow + Keras) on SageMaker to model cardholder transaction sequences, catching botnet attacks in real time while reducing false declines.
  • Deployed FastAPI + Featurespace ARIC inference microservices on EKS behind Java Spring Boot gateway services — sub-100ms scoring latency via optimized serialization and batch prediction paths.
  • Integrated predictive risk scores into the core payments gateway with Python and SQL, monitored via CloudWatch — securing billions in GMV at 99.99% uptime.
  • Automated retraining, hyperparameter tuning, experiment tracking and drift monitoring with SageMaker Pipelines, MLflow and Airflow for full regulatory auditability across model versions.
  • Defined typed API contracts and backend endpoints for the React + TypeScript analyst dashboard, surfacing live drift metrics, model version history and flagged transaction reviews.
  • Designed secure event-driven ML orchestration with Java, Spring Boot and Kafka — multi-threaded distributed services built for high reliability and horizontal scaling.
  • Aligned models to PCI DSS, PSD2 SCA and 3-D Secure, implementing PII controls and SHAP-based reason codes for declined transactions with full model lineage for audit.

Demand Forecasting & Catalog Intelligence

Owned demand forecasting and catalog enrichment for supply chain operations — end-to-end pipelines on GCP covering validation, feature generation, training, drift monitoring and automated retraining over terabyte-scale daily data.

  • Owned the end-to-end demand forecasting pipeline — validation, feature generation, training, deployment, drift monitoring and automated retraining — lifting forecast accuracy ~15% and cutting manual replenishment planning.
  • Contributed to a multi-modal catalog enrichment pipeline on GCP processing unstructured text and image data to close metadata gaps, supporting an estimated $20M+ annual GMV uplift.
  • Built time-series models (Prophet, ARIMA) on Vertex AI, orchestrating training, validation and experiment tracking through Kubeflow Pipelines and Airflow DAGs for automated retraining.
  • Trained distributed forecasting models across an estimated 2 TB of daily transaction and inventory data with PySpark, Dask and Ray — training time down ~40%.
  • Redesigned BigQuery partitioning and clustering across a multi-terabyte dataset — query costs down ~25% — and built a centralized feature store to standardize reuse across forecasting models.
  • Built Airflow, BigQuery and GCS workflows producing TFRecords for TPU training, integrating Multi-Task Learning frameworks to balance relevance against personalization.
  • Implemented label-aware BERT architectures to extract fine-grained product attributes from raw seller descriptions and customer reviews, cutting dependency on manual data across catalog pipelines.
  • Developed a computer vision pipeline (STN, CNNs, BiLSTM) to extract text and attributes from product images, resolving listings with missing or unstructured metadata.
  • Migrated keyword-based search to semantic search, contributing to indexing and retrieval optimization over millions of dense vectors on Milvus and FAISS.
  • Converted pandas workloads to PySpark for distributed processing, provisioned infrastructure with Terraform, and enforced code quality with pytest, Poetry and UV across parameterized, cache-aware KFP pipelines.
