Welcome to Vishwa's Blog
A digital realm of an Architect, where innovative solutions converge with business excellence.
With over 25 years of hands-on experience in Software Development, I am a seasoned Senior Solutions Architect specializing in architecting robust, scalable, and future-ready solutions that align with strategic business goals. I bring deep expertise across enterprise architecture, microservices, cloud platforms, and API ecosystems, ensuring high performance, availability, security, and maintainability.
In recent years, I’ve expanded into applied AI and generative technologies, actively designing intelligent assistants and RAG-based systems using Azure AI Foundry, OpenAI APIs, and GPT models. My focus is on embedding LLMs into enterprise-grade solutions, particularly in the FinTech domain, to enhance operational efficiency and decision intelligence.
As a visionary technologist, I’m committed to driving innovation and shaping transformative, AI-powered solutions that empower organizations to thrive in a rapidly evolving digital landscape. My approach is grounded in excellence, collaboration, and forward-thinking architecture strategies that deliver lasting value for businesses and society.
