Jaya builds end-to-end systems spanning data infrastructure, retrieval-augmented generation, LLM evaluation, and production-oriented application development. Current work includes Pulse, a job-market data platform with Airflow orchestration, an S3 medallion lake, PySpark transformations, Snowflake and dbt models, automated data-quality tests, and pull-request CI. Jaya also built an LLM service that converts Terms-of-Service documents into structured privacy and data-sharing risk reports using constrained outputs, Pydantic validation, grounding, and retries. At Accenture, Jaya built Snowflake ETL workflows and validation layers for retail reporting, including automated daily refreshes that removed a roughly 30-minute manual rerun. Jaya’s research includes a published real-time sign-language-recognition paper using YOLO and Bi-LSTM, as well as an empirical deep-GNN over-smoothing study across 2- to 64-layer models. Jaya is seeking AI engineering and data engineering roles beginning in January 2027. ## Services - Team Collaboration - Customer Service - Skilled Multi-tasker - Reliability - Communication - Python \(Programming Language\) - SQL - Snowflake - Apache Spark - Apache Airflow - dbt - Amazon Web Services \(AWS\) - FastAPI - Linux - Git - Large Language Models \(LLM\) - Machine Learning - React.js - Continuous Integration and Continuous Delivery \(CI/CD\) - Extract, Transform, Load \(ETL\) - Docker - PostgreSQL - LangChain - Prompt Engineering - PyTorch - Artificial Intelligence \(AI\) - Databases - Data Modeling - Data Warehousing - Full-Stack Development ## Highlights - Built Pulse, a production-standard job-market data platform with an eight-task Airflow DAG that ingests data from three APIs into an S3 medallion lake. - Implemented PySpark transformations and dbt staging and mart models in Snowflake for Pulse. - Added dbt tests that gate bad data and CI on every pull request for Pulse. - Built an LLM service that converts Terms-of-Service documents into structured privacy and data-sharing risk reports. - Used constrained LLM outputs, Pydantic validation, and a grounding-and-retry layer to make Terms-of-Service analysis usable programmatically. - Built a RAG-based document Q&A system with a double-check approach to reduce hallucinations. - Evaluated LLM and RAG systems with RAGAS metrics including recall, NDCG, and faithfulness. - Built Snowflake ETL workflows in SQL and Python for a retail client at Accenture. - Automated three daily summary-table refreshes with Snowflake Tasks at Accenture, removing an approximately 30-minute manual morning rerun. - Created SQL validation checks for schema drift, duplicate records, and malformed records, gating bad data before reporting tables. - Tuned recurring transformation queries and staged intermediate results to reduce redundant computation in daily reporting jobs at Accenture. - Built and monitored scalable data pipelines during Jaya’s Accenture experience. - Built and shipped end-to-end MERN application features at Food Integrity India LLP, including MongoDB collections, Express REST endpoints, and React components. - Worked with stakeholders at Food Integrity India LLP to convert business requirements into scoped frontend and backend changes. - Resolved responsive UI issues to improve mobile usability and tested API endpoints for reliable frontend-backend communication. - Published research on real-time sign-language recognition using YOLO and Bi-LSTM. - Conducted a deep-GNN over-smoothing study across 2- to 64-layer models using MAD and MADGap diagnostics. - Expected to complete a Master’s Degree in Computer Science at Virginia Commonwealth University in December 2026. - Earned a B.Tech. in Computer Science and Engineering \(Honors\) from Prasad V Potluri Siddhartha Institute of Technology. ## Experience - **Data Engineer at Accenture** (2025-02-01–2025-06-01) — Built Snowflake ETL workflows in SQL and Python for a retail client's datasets, and automated three daily summary-table refreshes with Snowflake Tasks, removing a ~30-minute manual rerun from the team's morning routine. • Wrote SQL validation checks for schema drift, duplicates, and malformed records, gating bad data before it reached reporting tables. • Tuned recurring transformation queries and staged intermediate results to cut redundant computation from the daily reporting jobs - **Full Stack Developer at Food Integrity India LLP** (2024-06-01–2024-08-01) — Built and shipped features for the client's MERN web application end to end, implementing MongoDB collections, Express REST endpoints, and React components for core user-facing workflows. • Worked directly with stakeholders to turn business requirements into scoped changes, then delivered them across both the frontend and backend. • Fixed responsive UI issues that made the app usable on mobile, and tested API endpoints to keep communication between frontend and backend reliable. ## Education - B.Tech. in Computer Science and Engineering \(Honors\) — Prasad V Potluri Siddhartha Institute of Technology - Master's Degree, Computer Science — Virginia Commonwealth University ## FAQ ### What does Jaya do?
