Microservices and Startups: A Journey of Complexity and Reward ( Using AWS Lambda)

Rewind to three years ago: the inception of our fintech startup. As the founder and CTO, I was poised with a critical decision, setting the technology direction for our newborn company. Although many startups typically lean towards a monolithic structure due to its simplicity, I chose to blaze a different trail by adopting a microservices architecture right from the start.
