• After nearly six years at Mambu and over 15 years in the fintech industry, I made a deliberate decision to step back and invest in myself. This career break was not a pause - it was a strategic pivot toward mastering the technologies that are fundamentally reshaping financial services and enterprise operations.
• During this period, I immersed myself in the rapidly evolving AI landscape, gaining hands-on experience with a comprehensive range of tools and platforms:
• Large Language Models & AI Assistants: Developed proficiency in leveraging ChatGPT, Claude, Gemini, and other foundation models for complex problem-solving, content generation, and workflow automation. Explored prompt engineering techniques to maximize output quality and efficiency.
• AI-Powered Development & Productivity: Integrated tools such as GitHub Copilot, Cursor, and various AI coding assistants into technical workflows, understanding how these capabilities accelerate software development and system design.
• Automation & Integration Platforms: Built practical knowledge in connecting AI capabilities with business processes - bridging the gap between cutting-edge technology and real-world operational needs.
• Generative AI Applications: Experimented with image generation, document processing, and multimodal AI applications to understand their potential impact on customer experience and operational efficiency in financial services.
• AI Strategy & Implementation: Studied emerging frameworks for responsible AI adoption, focusing on governance, risk management, and practical implementation strategies relevant to regulated industries.
• The insights gained during this period directly informed the founding of waiti, where I now help fintech companies and financial institutions navigate their own AI-enabled transformation journeys.
