My Tech Journey

As a non-technical partner in a company that developed a cloud-based point-of-sale system for businesses, I experienced firsthand the challenges and frustrations of managing payments without a reliable API. My co-founder, Emmanuel Amah, and I had a vision of creating a seamless payment experience for businesses, allowing them to accept and make payments through mobile phones. However, without a proper payment integration solution, we faced numerous obstacles and had to invest a significant amount of money in connecting to different payment processing companies.

The process of managing payments became increasingly difficult, and we found ourselves struggling to provide a smooth and efficient payment experience for our customers. It was clear that we needed a technical solution to bridge the gap between our point-of-sale system and the various payment processors.

Driven by our desire to overcome these challenges and deliver a superior payment experience, I made the decision to delve into the technical aspects of application programming interfaces (APIs) for payment processing. I embarked on a personal project to build a payment API that would streamline payment integration for merchants' applications.

The experience of navigating the complexities of payment processing without a reliable API served as a motivation for me to understand the intricacies of APIs and their significance in the world of payment transactions. I was determined to create a solution that would simplify the payment process for businesses, ensuring seamless transactions and enhanced security.

This personal journey led me to develop the Sendpay API, a powerful payment API with a focus on simple integration, secure transactions, and support for multiple payment methods. By leveraging my firsthand experience and insights gained from our previous venture, I aimed to address the pain points that merchants face when dealing with payment processing.

Through the Sendpay API, I aspired to provide businesses with a robust and reliable solution, enabling them to seamlessly integrate payment processing into their applications. My personal story of overcoming the challenges of managing payments without an API fueled my commitment to developing a comprehensive payment solution that would empower businesses and enhance their operations.

By sharing this story, I hope to convey the passion and dedication that drove me to work on the Sendpay API project and how it directly relates to the challenges and frustrations I encountered in my previous venture.
