Our team

Toptal was created by engineers. We are entrepreneurs, all passionate about working with top engineers and exciting companies from all over the world.

Taso Du Val


With experience as a lead engineer at Fotolog (acquired by Hi-Media for $100m) and Slide (acquired by Google for $228M), as well as experience with his own start-ups, Taso brings top engineering knowledge and management experience to Toptal. While running a small engineering consulting firm, Taso recognized that while many of his co-workers overseas were just as good as his friends and colleagues at Google, Facebook, and other companies with distinguished engineering talent, it was simply very difficult for such companies to connect with the right engineers remotely. Toptal was thus created as a solution to the sky-rocketing demand for top engineers in Silicon Valley, US, and Europe despite the shrinking local graduation rates of such engineers.

Breanden Beneschott


Breanden has worked as founder, CTO, developer, designer, and consultant for companies as diverse as smsPREP, Smith + Jones, 2Tor, and Lightspeed Venture Partners. He has a BSE in Chemical Engineering from Princeton University, and in December 2010, he was selected as Princeton’s first and only student speaker for TEDxPrincetonU where he gave a talk on time optimization and project management. Having been on both sides of the hiring equation as an engineer and team lead, Breanden combines his technical expertise and management experience to ensure that clients, developers, and team members at Toptal have a smooth, successful experience as the company rapidly scales.

Alexander started as a senior developer at NetCracker Technology Corp. before moving to a technical manager position, leading teams of up to 10 developers.

At Toptal, Alexander combines his experience in both corporate and start-up environments to lead internal technological development. Alexander has a MS in Applied Mathematics and Physics from the Moscow Institute of Physics and Technology and does further research in Computer-Human Interaction while completing a PhD at the Institute of Control Sciences of RAS.

Alvaro has worked as lead developer, ERP engineer, founder, consultant, recruiter, and BI specialist for companies such as Kenos, The Bristol Group, and The Wornick Company. His experience also encompasses working for various Brazilian chemical companies and taking part in several international projects throughout Europe. Alvaro participated in the F.I.R.S.T international robotics competition where his team, sponsored by Johnson & Johnson Brazil, placed third. As a college freshman Alvaro placed third at the Brazilian Nationals for the Microsoft Imagine Cup Competition in the Software Design Category. In high school, he was a Top 10 World Finalist.
