  • Architected a production-scale Agentic AI platform leveraging autonomous LLM agents and a 500+ rule validation engine to automate profile and photo moderation for millions of users, enforcing policies for contact information, competitor promotion, profanity, relevance, and unsafe content.
  • Engineered a parallel LLM inference engine with asynchronous request execution, reducing end-to-end validation latency by 30% (to 1s) while increasing throughput for real-time moderation workloads.
  • Provisioned highly available AWS infrastructure using Terraform, automating deployment of VPCs, ECS, EC2, S3, IAM, and networking resources, reducing infrastructure provisioning time from hours to minutes.
  • Containerized AI microservices using Docker and implemented CI/CD pipelines with GitHub Actions, enabling zero-touch deployments and faster production releases while integrating PostgreSQL for profile metadata and validation logs.
  • Implemented production observability using Grafana, monitoring API latency, throughput, GPU/CPU utilization, and infrastructure health with proactive alerting, maintaining 99.9% service availability.
  • Designed domain-specific ML models including BLSTM classifiers for name-to-gender and name-to-religion prediction, and fine-tuned Google CANINE for robust character-level understanding of multilingual names, slang, and spelling variations.
  • Reduced manual moderation effort through end-to-end AI automation, delivering operational savings exceeding INR 1.2 million per month while improving moderation consistency and user profile quality across production systems.
  • Designed and deployed a production-grade Agentic RAG chatbot with hybrid retrieval (semantic + keyword) enabling context-aware responses and intent-driven action execution for complex user queries.
  • Developed a modular agentic architecture supporting tool invocation, multi-step reasoning, persistent memory, and backend workflow automation, reducing resolution time for support queries significantly.
  • Scaled with robust APIs, caching, and monitoring pipelines, driving measurable improvements in user engagement, response accuracy, and support automation in production.

Principal AI Engineer

Matrimony.com Limited · Oct 2025 – Present

  • I currently work as a Principal AI Engineer at Matrimony.com, where I design and build large-scale AI solutions that improve profile and photo moderation using Agentic AI, Large Language Models (LLMs), multimodal AI, and cloud technologies.
  • One of my key contributions has been leading the development of a real-time AI-powered validation platform that automates profile and photo moderation for millions of users.
  • The platform uses autonomous AI agents and an extensive rule engine to detect issues such as contact information, competitor promotions, profanity, irrelevant content, and unsafe images.
  • To support real-time performance, I optimized the inference pipeline with parallel and asynchronous processing, reducing response time by around 30%.
  • I also built the cloud infrastructure on AWS using Terraform, containerized services with Docker, and implemented CI/CD pipelines through GitHub Actions for reliable and automated deployments.
  • The platform is continuously monitored using Grafana, ensuring high availability and stable production performance.
  • Beyond platform engineering, I have developed machine learning models for tasks such as name-to-gender and name-to-religion prediction, and fine-tuned Google's CANINE model to handle multilingual names, spelling variations, and slang effectively.
  • These AI solutions have significantly reduced manual moderation effort while improving consistency and user experience, resulting in operational savings of over ₹12 lakh per month.
  • Additionally, I designed and deployed an Agentic RAG-based chatbot that combines semantic and keyword search with intelligent agents to provide context-aware responses and perform actions based on user intent.
  • The chatbot supports multi-step reasoning, tool integration, and scalable knowledge retrieval, enabling users to receive accurate answers and complete tasks seamlessly.
HCL Tech

Tech Lead (AI/LLM ENGINEER)

HCL Tech · Oct 2023 – Oct 2025

Not yet confirmed
  • Developed an advanced document-based Q&A chatbot with follow-up question generation, source-linked answers, buffer/cache memory, and persistent chat history.
  • Designed and orchestrated a data pipeline for Selenium-based approach, parsing, image-to-text extraction (Claude 3.0 Vision), and metadata enrichment, integrated into an Agentic RAG system by hybrid retrieval (BM25 + semantic search + reranking) with ChromaDB embeddings.
  • Deployed the solution on AWS with FastAPI and Bedrock LLMs, achieving 96% accuracy and $2.4M projected cost savings.
  • Fine-tuned LLaMA 3-70B using LoRA and QLoRA on a custom-curated dataset for domain-specific QA, enhancing response accuracy, contextual depth, and reducing hallucination in complex query scenarios.
  • Developed a real-time Driver Distraction Detection system using a custom ResNet-34 CNN (99.16% accuracy) and MediaPipe for face landmark tracking, optimized with Intel OpenVINO for low-latency inference.
  • Built a Streamlit-based UI with an integrated analytics dashboard and deployed the solution as Docker microservices for cross-platform, real-time driver monitoring and alerting.

Technical Lead

HCLTech – Engineering and R&D Services · Oct 2023 – Oct 2025

Not yet confirmed
  • At HCLTech, I developed an AI-powered document-based Q&A chatbot that enabled users to interact with enterprise documents through natural language and receive accurate, source-backed answers.
  • The chatbot supported follow-up questions, maintained conversational context with buffer memory, and provided persistent chat history for a seamless user experience.
  • I designed and implemented an end-to-end document processing pipeline that included web scraping with Selenium, document parsing, image-to-text extraction using Claude 3 Vision, and metadata enrichment.
  • The processed data was integrated into an Agentic RAG architecture using hybrid retrieval techniques, combining BM25, semantic search, reranking, and ChromaDB embeddings to improve the relevance and accuracy of responses.
  • The solution was deployed on AWS using FastAPI and Amazon Bedrock LLMs, achieving approximately 96% answer accuracy while delivering an estimated cost saving of $2.4 million.
  • Additionally, I fine-tuned Llama 3 70B using LoRA and QLoRA on a custom domain-specific dataset, improving contextual understanding, enhancing response quality, and significantly reducing hallucinations for complex enterprise queries.
