I'm Yuvraj.
Full-Stack Developer leveraging Java, Next.js, FastAPI, and AI/ML to build scalable applications.
I'm a computer science engineering student (AI specialization) and developer based in India. I focus on building production-grade full-stack applications, intelligent multimodal RAG systems, and performant backend services with Java, Python, and TypeScript.
Engineering Principles & Architecture
Core philosophies guiding how I design, optimize, and scale software systems.
Systems Latency & Throughput
Database & Backend OptimizationArchitecture is measured in milliseconds. Prioritizing JDBC connection pooling, indexed query execution plans, and asynchronous FastAPI worker pipelines to compress backend roundtrips from 500ms down to sub-80ms for enterprise loads.
Deterministic AI & Production RAG
Beyond Toy LLM WrappersMoving beyond basic prompt engineering into resilient retrieval pipelines. Engineering hybrid BM25 + dense vector embeddings (pgvector/ChromaDB), contextual semantic chunking, cross-encoder reranking, and low-latency token streaming.
Edge Efficiency & Quantization
Computer Vision & Deep LearningBuilding neural networks for compute-constrained production environments. Training custom CNN architectures with TensorFlow (97.5% accuracy), applying INT8 quantization and structured pruning to compress payload sizes by 35% with zero inference degradation.
Type Safety & Resilient Delivery
Full-Stack Hygiene & ContainersStrict end-to-end typing across TypeScript and Java. Designing decoupled microservices with Docker containerization, strict error boundaries, transactional ACID guarantees, and automated CI/CD deployment pipelines.
