Backend Engineer @ Inovaare | AI/LLM Systems | Python, Java, AWS EKS

About

Backend engineer focused on building AI/LLM systems into production data pipelines, not just chat layers on top of them. Over the last 3 years I've rewritten legacy Java systems into cloud-native Python microservices on AWS, and built a hybrid retrieval-augmented generation pipeline from scratch, combining dense and sparse retrieval with cross-encoder reranking and LLM-hosted inference. Comfortable across the full backend stack - Java, Python, Node.js, Angular, Kubernetes, PostgreSQL, MongoDB, but my focus now is where those systems meet LLMs: schema inference, data normalization, and retrieval architectures that hold up at scale.

Work experience

Associate Product Engineer at Inovaare Corporation, Aug 2024 - Present · 2 y, Bhubaneswar, Odisha, India, • Rewrote the core data-scrubbing engine from a Java monolith into a Python/Django microservice on AWS EKS: chunk-based scrubbing, pooled DB connections, and async AWS Lambda offload — processing 100K+ records per run in 3–4 minutes with 35% fewer validation errors. • Migrated the pre-scrub schema validation and correction stage into an AI-assisted Python/FastAPI microservice: maps spreadsheets onto 135+ MongoDB-defined schemas via Hungarian-algorithm column assignment, with a Groq LLaMA 3.3 70B fallback for low-confidence columns. • Owned Kubernetes and AWS infrastructure: EFS-backed volumes, initContainer-based config decryption, ECR pipelines, and a Lambda runtime migration across five SAM templates. • Implemented multithreaded Java REST APIs with OAuth 2.0, improving throughput 3x; led the SVN → Bitbucket migration with CI/CD pipelines stabilizing monthly releases.
