Every great innovation starts with a fascinating story. Mine is woven with challenges overcome, lessons shared, and above all, the creation of digital products that reach thousands of users and democratize access to technology. I am the craftsman behind the code that has transformed the way startups take off and connect with their audience.

I am an enthusiast of startups and passionate about creating digital products that have the potential to change the world. Nearly a decade's experience in software development has allowed me to be part of innovative teams and contribute to projects in both their inception and phases of expansion and improvement. I have worked with startups and large companies, creating from scratch and optimizing existing projects with best practices.

Throughout my career, I have had the privilege of participating in a wide range of industries—from IoT to CRM systems and geolocation, covering backend with Node.js and frontend with React.js, as well as mobile app development in Flutter and React Native. Thanks to these experiences, I am fluent in databases such as MongoDB and PostgreSQL and have been part of the growth of projects up to thousands of active and committed users.

In 2022, with vision and leadership, I founded Dynasty Online to offer staffing solutions to companies in the United States, opening opportunities for many other developers like myself to expand their professional horizons.

If you are looking for someone who can help you assemble and lead a highly efficient software development team and who focuses not only on technology but also on the success of the business, I would be delighted to consult with you. We can define the path for your innovative ideas to become captivating market realities.

To discuss how we can work together and take your vision to the next level, I invite you to schedule a 30-minute call with me on my Calendly: [https://calendly.com/davidlondono9/30min], or if you prefer, send me an email at david@dinastyonline.com and let's begin to sketch the future.

I’m happy to share that I’m starting a new position as Founder at AuraVibes!
