What I'm looking for

I'm seeking an AI/ML or GenAI Engineer role focused on building production-ready AI solutions. My experience includes LLMs, NLP, AI security, fine-tuning, model evaluation, and dataset engineering. I'm interested in RAG, agentic AI, and Python-based systems, preferably at an established technology company in Noida, Delhi NCR, or remote.

At Quokka Labs, I work on LangProtect, training RoBERTa-based NER models to identify PII, PHI, PCI, and secrets across 100+ sensitive-data entities.

I built and cleaned training datasets of about 200K samples per entity pipeline, using deduplication, balancing, hard negatives, and OCR and formatting variations.

I also built a production evaluator that measures TP, FP, and FN on live traffic, identifies weak entities, and surfaces recurring model failures. For prompt-injection detection and security routing, I benchmarked local decision models including Laya, Jev, and Kev.

Alongside this work, I engineered a RAG-based conversational pipeline for a real-time AI avatar and shipped production iOS apps using Swift, SwiftUI, and UIKit, including AI-powered features and 4+ App Store releases.
