Alejandro Hernandez

Solution Architect
Córdoba, Argentina

Alejandro got his bachelor's degree in software engineering in 2005 and has since been working for software companies of all sizes from all around the globe as a freelancer.

Part of engaging with any new technology is the uncertainty of finding a job that requires you to use what you've learned. Thanks to Toptal, I've had a steady stream of projects with clients from the very beginning. My Toptal clients are always pushing the limits of the technology to give their users the best user experience in their markets.

Rogério Araújo

Senior Software Engineer
Goiânia, Brazil

Rogério is a full-stack developer with 15 years of experience with software development and architecture. He has worked on several projects for customers in Brazil and globally. The range of projects include mobile, applications, desktop, and enterprise search applications.

Toptal has created an amazing community of developers who are all extremely passionate about helping each other solve any problem. For me, the best part has been that after learning a new language and starting to engage with other Toptal developers about the technology, I quickly landed two jobs in less than one month, and both were great experiences.
