AI Systems

ML Engineer with 2.6 years taking AI from idea to production โ€” RAG pipelines, LLM applications, NLP systems, and MLOps infrastructure. I write the code, deploy the model, monitor the drift, and keep it running.

Targeting Fintech ML Roles

I'm a Software Engineer specialising in ML/AI โ€” I've spent 2.6 years building systems that actually run in production, not just experiments that live in notebooks. My stack spans RAG pipelines, LangChain, LLM fine-tuning, NLP, and MLOps on AWS and Azure. I'm now deliberately targeting ML Engineer roles in Fintech and Banking โ€” actively studying AML systems, fraud detection patterns, and financial ML to complement my production engineering background. If you need someone who ships reliable AI and learns domain fast, let's talk.

Experience

2.6 years of building and deploying real AI systems โ€” RAG, NLP, computer vision, MLOps โ€” across multiple production environments

Associate IT Engineer โ€” ML/AI
ANB Solutions ยท Hyderabad
  • Built and deployed a RAG-based ChatBot using LangChain and Azure Cosmos DB โ€” handles 22+ topic domains with <3 second end-to-end latency in production
  • Engineered a Theme Extraction pipeline that automatically surfaces 200+ customer pain points using Few-Shot prompting and Chain-of-Thought reasoning โ€” replacing manual analysis
  • Shipped Multi-head DistilBERT classifier to production โ€” flags 22+ complaint categories at 95% real-time accuracy on live multi-source data streams
  • Built PySpark-based Knowledge Base ingesting real-time survey data at scale โ€” feeds downstream ML models
  • Deployed anomaly detection module that cut manual monitoring workload by 80%
  • Built ensemble classifier (XGBoost + Random Forest) for repeat caller prediction โ€” delivered 60% operational cost reduction
Machine Learning Engineer
YUGASYS ยท Bengaluru
  • Built and deployed a text classification model that improved document categorisation accuracy by 18% โ€” reduced manual review cycles by 30%
  • Researched and evaluated ChatGPT, LLaMA, and BLIP-2 for production readiness โ€” wrote internal assessments that shaped engineering decisions
  • Fine-tuned LLaMA using PEFT / LoRA โ€” reduced inference cost significantly while maintaining task performance
  • Built and shipped YOLO-based computer vision pipeline for real-time license plate and helmet detection โ€” deployed in the Emotyx safety compliance product
  • Designed NLP sentiment analysis system achieving 90% accuracy on held-out test data โ€” integrated into client-facing reporting
