Building the infrastructure that makes AI applications actually work.

Ritinpaul Singh
Open to roles (2026)

I started coding because the systems I depended on kept breaking. Now I build the ones that do not.

I am a Computer Science Engineering student at SRM University (Batch 2027, 9.31 CGPA) and the Founder of Nuuvixx, building autonomous multi-agent governance and runtime systems.

My work lives at the intersection of backend engineering and LLMOps: shipping systems that are observable, fault-tolerant, and actually scale under production traffic.

Currently focused onMulti-agent governance, distributed task queues, and LLM evaluation with RAGAS.

Technical Accreditations4x Certified: AWS Machine Learning, AWS AI Practitioner, AWS Cloud Practitioner, SAP GenAI.

TrustNet: Deep Abstaining Classifier

Selective Prediction & Fraud Detection with Deep Abstaining Classifiers

Traditional ML classifiers are forced to output a prediction even on borderline, high-uncertainty transactions, causing high false negatives and undetected financial fraud.
