People enjoy working with me 🤗
I've been lucky to work with amazing people from various backgrounds, countries, and cultures throughout my career. Here is what they say about me:
Sebastian Almnes
Co-Founder & CEO at SpringI’ve had the chance to work with many developers over the years, but Emmanuel stands out as the most talented Rails developer I’ve worked with. He brings more than just technical skill — he brings thoughtfulness.
... Read more
He’s not afraid to challenge assumptions or start a discussion if it means we get to a better outcome. That kind of mindset has elevated the quality of our code and our team culture.
What I admire most is his ability to adapt. Whether the requirements are shifting, or the context isn’t perfectly defined, he never gets stuck. He stays focused, finds a path forward, and delivers solid work — always with care and pride in the result. His passion for what he does shows up in the details and in the energy he brings to the team.
If you get a chance to work with him, take it.

I've had the chance to work closely with Emmanuel, and I can honestly say he’s probably the Rails developer who knows the framework best out of anyone I’ve worked with. His technical knowledge is solid, but what really stands out is how he uses it to help the whole team.Having someone like Emmanuel on a team is a game changer. He motivates people around him just by the way he works—sharing what he knows, asking good questions, and always looking for ways to improve things. It naturally pushes everyone to learn and grow.

He cares about clean code, has a strong engineering mindset, and is always looking out for the quality of the codebase. He doesn't just build what’s asked—he makes sure it’s done right and looks for chances to make it even better.
If you’re looking for a Rails developer who’s skilled, thoughtful, and great to work with, I’d definitely recommend Emmanuel.

Consultant, Former Co-Founder & Former CTO at Spring... Read more
I hired Emmanuel as a Senior Software Engineer at Spring in June 2024 and had the pleasure of working with him until I left the company at the end of that year. He left a lasting impression.
Emmanuel quickly proved to be an excellent developer. We started Emmanuel out with a tough problem, by asking him to improve our intricate payment-processing system. Emmanuel impressed us by quickly getting a good grasp of both the business and code-aspects of the problem we were trying to solve, and soon started making improvements on both.Emmanuel holds himself to a high standard when it comes to code quality, and helped raise the bar for the rest of the team. A big part of this is that he’s a thorough reviewer, who gives clear feedback to other team members and shares his knowledge in a pedagogic manner.

Where many developers have a tendency to reinvent the wheel, Emmanuel deeply understands the tools he's working with (in our case, Ruby on Rails and Hotwire), and is able to utilize them to their full extent. The result is clean, standardized code, that is more easily interpreted by other developers.
Just as important, Emmanuel is pragmatic, and able to balance the need to refactor and improve code against the overarching goal of making a better experience for the end-user. It’s not often you find someone as passionate about all aspects of software engineering as Emmanuel.
Any team would be lucky to have him.

Emmanuel can deliver quality output in a short amount of time while still considering broader implications such as maintainability and architecture.

He stays current and understands the advantages and disadvantages of recent frameworks and how they can help but more importantly sometimes hinder a company's objectives. His input is always well thought out and insightful.
