Greetings to all 👋, I'm Ujwal Tewari.

I have been working in Reinforcement learning, control optimization-based techniques and multi-agent systems. In addition to this, I work in the real world deployment of AI-based models for automated control decision processes using both RL and evolutionary strategies in cases where human intervention would otherwise be difficult.

Currently, I serve as a Senior Research Scientist-2 at Games24x7, where I have led multiple initiatives in conversational AI, reinforcement learning, and applied generative AI. My expertise spans:

• Conversational AI: Multilingual chatbots with language detection/translation, intent classification, and optimized static routing to reduce LLM overhead.
• Evaluation & Safety: Real-time LLM evaluation pipelines measuring hallucination, relevancy, and completeness; architect of GameGuard, a model-agnostic safety system achieving 99% jailbreak reduction.
• Reinforcement Learning: Multi-agent RL for traffic intersection management and HVAC optimization using LSTM + RL; goal-oriented dialog systems.
• Personalization & Recommenders: State-wise CPM/FDA models delivering +5.94% LTP and saving ₹70 lakh/month by eliminating third-party enrichment; localized multimodal recommender systems.

I have also been working as an AI Ambassador at Intel Corporation, a classroom mentor for the Deep Reinforcement Learning nanodegree at Udacity and a tech blogger at Medium in Analytics Vidhya.

Have worked in ML and Research as Senior Applied Scientists for more than 6+ years with good track record of ML papers in reputed conferences

Alongside industry deployments, I have authored application-oriented publications (NeurIPS Deep-RL Workshop 2019, ITSC 2020, submissions to CODS-2025 & EMNLP-2026 ARR) with expertise in model development to deployment lifecycle

My Interests are:

Machine Learning, Reinforcement Learning, Knowledge Graphs, Natural Language Processing and Computer Vision
