Raja focuses on making generative AI useful, accurate, and dependable in products with real users, data, and operational constraints. Raja builds retrieval workflows for Ensai Support, an in-app assistant that answers product questions from Ensora documentation, integrates those workflows with a PHP, JavaScript, and MySQL platform under HIPAA requirements, and evaluates answers against source documentation before release. Raja’s strengths include Python, FastAPI, LangGraph, retrieval-augmented generation, vector search, LLMs, agentic workflows, conditional routing, evaluation, source attribution, and fallback design. Previously, Raja spent about 20 months at Goldman Sachs integrating internal generative AI services into reporting workflows through Python and REST APIs and building Pandas pipelines for large financial datasets. Raja began at Tata Consultancy Services, developing Python/Django back ends and React front ends. Raja also built CareFusion-AI, an end-to-end RAG medical assistant using PDF ingestion, HuggingFace embeddings, Pinecone, LLaMA-3, LangChain, Docker, GitHub Actions, and AWS. Raja is seeking full-time AI Engineer or Forward Deployed Engineer opportunities, including customer-facing roles that solve real-world technical problems. ## Services - LangGraph - Docker - Retrieval-Augmented Generation \(RAG\) - FastAPI - Amazon Relational Database Service \(RDS\) - AWS Lambda - DevOps - Amazon EC2 - Elastic Stack \(ELK\) - Terraform - ECS - Amazon S3 - Role-Based Access Control \(RBAC\) - Spring Boot - Continuous Integration and Continuous Delivery \(CI/CD\) - Amazon Dynamodb - Bootstrap \(Framework\) - Application Programming Interfaces \(API\) - Cascading Style Sheets \(CSS\) - RESTful WebServices - XML - JSON - HTML5 - TypeScript - User Interface Design - Full-Stack Development \(Frontend-focused\) - JavaScript - React.js - Wireframing - User-centered Design ## Highlights - Builds retrieval workflows for Ensai Support, Ensora Health’s in-app assistant for product questions grounded in Ensora documentation. - Integrates AI workflows with Ensora Health’s PHP, JavaScript, and MySQL platform under HIPAA requirements. - Works on AI capabilities for an EHR platform supporting more than 200,000 therapists and clinicians. - Tests assistant answers against source documentation before release and uses source attribution and evaluation to support reliable, grounded responses. - Built an enterprise IT-support AI assistant with intelligent retrieval, evaluation, web-search fallback, and conditional workflow routing. - Designs agentic AI workflows using conditional routing, evaluation steps, fallback mechanisms, and vector databases. - Proactively tests edge cases and failure scenarios during development to help prevent production issues. - Spent about 20 months at Goldman Sachs integrating internal generative-AI services into workflows with Python and REST APIs. - Built Pandas pipelines at Goldman Sachs to handle large financial datasets and reduce manual reporting work. - Built Python/Django back ends and React front ends for client applications at Tata Consultancy Services. - Built CareFusion-AI, an end-to-end RAG medical assistant with PDF ingestion, HuggingFace embeddings, Pinecone vector search, LLaMA-3, and LangChain. - Used Docker and GitHub Actions to ship CareFusion-AI to AWS. - Built a Python/Pandas web scraper. - Built a Power BI dashboard for weather and air-quality data. - Built a credit-card-fraud-detection model that addressed a 99.8/0.2 class imbalance using SMOTE. - Is developing a text-to-image service with FastAPI. - Maintains project work on GitHub at github.com/Kanaparthi89. ## Experience - **AI Application Engineer at Ensora Health** (2026-01-01–present) - **Full Stack Engineer – Data & AI Workflows at Goldman Sachs** (2024-11-01–2025-12-01) - **Software Engineer at Tata Consultancy Services** (2021-10-01–2023-12-01) ## Education - Master's degree, Computer Science — Nova Southeastern University ## FAQ ### What does Raja do?
