If you want a reliable, consistent, and beautiful brand design that connects with your audience then you’re in safe hands with Gabriel. 11/10!

Gabriel did a fantastic job on urgent
Game Design projects!

He was communicative, responsive to feedback, and thoughtful in how he translated ideas into strong, user-centered design concepts.

His background in designing educational games and working on the UX of MangaHigh’s products was clearly evident— he brought both creativity and usability to the table.

And the best part? It worked. We saw record engagement, and schools still talk about it years later. Overall, Gabriel was a pleasure to work with!

Back at Mangahigh, we were brainstorming how to boost student engagement— While the rest of us were still figuring out how it might work, Gabriel quietly sketched out the entire framework!

Landing pages designed to convert. Leaderboards that kept schools coming back daily. Trophies and digital medals that made kids feel like heroes.

It wasn’t just design. It was systems thinking, gamification, and emotionally intelligent storytelling, all wrapped into one cohesive experience.

If you’re lucky enough to have Gabriel Leni on your team—hold on tight! He is incredible.

Gabriel was a brilliant asset to the team and someone I wish I could take with me throughout my own career!

His skills helped define and evolve the brand strategy whilst supporting peers in all areas of the business to ensure a consistency and quality throughout. Alongside his exceptional design skills, Gabriel was a brilliant mentor to junior designers while tackling large projects on his own for the marketing team.

I highly appreciated his teamwork, expertise and natural creative drive which make him a brilliant person for anyone who works with him!

Of all the candidates we interviewed, Gabriel was the only one who could genuinely deliver everything he said he could.

Gabriel combines strong creative judgement with the ability to work independently, solve problems quickly and take ownership of complex projects from start to finish. He proved himself to be a highly capable and versatile senior designer who could be trusted to turn difficult briefs into finished work.

His breadth of skills, from visual design and complex reports to digital, motion and technical creative work, meant he could take on an unusually wide range of projects and deliver them to a high standard.
