About Me

I'm a technology enthusiast who thrives on solving complex problems through innovative solutions. With over two decades in the tech industry, I've discovered that the most rewarding aspect of my work is transforming challenging business requirements into elegant, scalable technology architectures that drive real impact.

As a TOGAF-certified Enterprise Architect, I specialize in designing and implementing cutting-edge solutions across cloud platforms like AWS and Azure. My expertise spans multiple industries—from public sector modernization to telecom infrastructure, banking systems, and insurance platforms—where I've consistently delivered solutions that not only meet immediate needs but anticipate future challenges.

Currently at CAST, I lead presales and solution architecture for Software Intelligence platforms, helping organizations across India, Middle East, and APAC transform their IT landscapes. My approach combines deep technical knowledge with strategic thinking, ensuring every solution I architect delivers measurable business value while embracing emerging technologies like AI and machine learning.

What drives me is the puzzle-solving nature of technology challenges. Whether it's migrating legacy systems to the cloud, optimizing application performance, or designing resilient architectures for digital transformation, I approach each problem with curiosity and determination to find the most effective solution.

My entrepreneurial spirit led me to found and architect NyaySamwad, an advanced AI-powered legal chatbot that demonstrates my ability to identify market opportunities and execute innovative solutions. This project showcases my business acumen in recognizing the need for accessible legal information and my technical leadership in building a sophisticated RAG-based system from the ground up, combining cutting-edge AI with practical business value.

Beyond my professional work, I'm passionate about knowledge sharing through my podcast and YouTube channel, where I explore the latest in enterprise architecture, emerging technologies, and digital innovation trends. I believe in the power of community learning and regularly engage with fellow technologists to exchange ideas and insights.

When I step away from the screen, you'll find me experimenting in the kitchen—where I apply the same methodical, creative problem-solving approach I use in technology—or out on a long run, which gives me the mental space to think through complex architectural challenges and innovative solutions.

Innovation & Leadership

NyaySamwad - Advanced Serverless AI Legal Chatbot

Proprietary NyayRAG System

Founded, architected and developed a scalable AI legal chatbot for Telegram and WhatsApp, evolving the core engine from a standard conversational model to a specialized Retrieval-Augmented Generation (RAG) system. This advanced solution is built to deliver highly accurate and context-aware legal information.

Key Technical Contributions:

Proprietary RAG System

Designed and implemented a custom RAG solution named NyayRAG, trained on a curated corpus of public legal documents to provide domain-specific and authoritative responses.

Advanced AI Integration

Developed the system on AWS Bedrock, leveraging its foundation models and capabilities to power the RAG and conversational AI components.

Agentic Framework Development

Currently working on transitioning the system towards an Agentic RAG framework, creating multi-step workflows to automate and streamline responses for complex legal use cases.

Serverless Architecture

Utilized AWS Lambda for business logic and Amazon DynamoDB for scalable chat data storage, ensuring high availability and cost-effective operations.

Impact: This project highlights deep expertise in business acumen, problem solving, solutions architecture, advanced generative AI development (RAG and Agentic systems), serverless computing, and the strategic use of AWS Bedrock to build sophisticated, domain-specific AI applications.
