Our Team

Leonardus Adi Prasetya

Director & Principal Designer

Leo is a product designer and developer based in Singapore, weaponising his experience across multiple industries including medical technology, consumer electronics, and the arts. His work has produced numerous IPs and patents for his clients, and he has built the prototypes for many a company in the current start-up ecosystem.

When not glued to the soldering station, he can be found rock climbing, tending to his balcony garden, or annoying his cat.

Evelyn Goh

Head of Operations

Evelyn is a high-achieving MBA graduate with experience across multiple fields due to her varied background, including research, clinical healthcare, U.S. politics, and law.

Her experience in management across hugely diverse industries, and in stressful situations with huge numbers of people, has allowed her to thrive with us. She speaks English, Mandarin, and Indonesian fluently, but is also conversational in Spanish, French, and Japanese.

In her free time, she can be found either sailing or in the kitchen, learning to cook and bake challenging dishes.

Daniel Righetti

Senior Designer

Daniel is a young designer from Australia who joined ADI when he first moved to Singapore in 2018, helping Leo shift from being a one-man company to a functional, effective, and creative design house. He has been heavily involved in the digital and physical aspects of design, allowing him to become proficient in his understanding and execution of concept sketching and ideation, 3D modelling, product development, prototyping, testing, and designing for manufacturing.

Daniel enjoys the challenge of designing and problem solving for complex and unique projects that ADI tends to attract, which often involve an interesting mix of design, mechanical and electrical engineering, and physics.

Outside of work, Daniel likes to meet up with friends for a laugh and a beer (or ten). He’s also an avid movie-goer, gamer and chess player.

Mohan Raj

R&D Engineer

Mohan is our beloved R&D Engineer who has been with ADI since early on. With top-notch skills and a loyalty that is hard to beat, Mohan is creative, intelligent, affectionate, and an incredibly hard worker. His passion, quick learning, and adaptability in fast-moving and unfamiliar situations make him an asset with our R&D department.

His affable, consistent, present nature endears him to long-time clients, who often request him for complicated maintenance and updating tasks as well. There is no one better suited to handle difficult tasks like those than Mohan.

In his free time, Mohan is a family man through and through. You’ll find him at home taking care of the people he cares about, and chatting their ears off about sports, especially soccer and sprint for which he was nationally recognised in school.

Teo Hong Zhang

Project Manager

Hong Zhang is a soft-spoken, reliable member of our team – when you ask him to do something, it will appear on your desk on the deadline requested, pristine and exceeding every possible given requirement. We don’t know how he does this, but it must be some kind of magic because we’ve never seen him panic over anything.

His views on design are smooth, strong, and deeply-set. He believes in the best of everyone and everything, and in fully realising the depth of his work and designs. His mild attitude belies a fierce, insightful, and passionate designer.

In his free time, Hong Zhang is a tutor and organises multiple outreach events for the community. He is also a calligraphy enthusiast, exploring his interest in typography and design. He goes by the alias @thehappyzest, which you can use to find him online.

Nicholas Phipps

Electronics Design Engineer

We’ve been headhunting Nicholas since he interned with us for a short two months, and after he graduated from the University of Surrey, we were ecstatic when he agreed to come back to us. Straightforward and capable, his love for tinkering with components is matched only by his dry, dry wit.

With his single-minded determination, hard work, and incredible mind, Nicholas has been a force to be reckoned with and is currently leading some of our most major electronics projects. He offers incredible insight and experience into aspects previously unthought of, and he has easily elevated our work to the next level.

In his free time, Nicholas is the average millennial, watching YouTube videos and playing games.

Deevagaran “Deeva” Purushothaman

Visuals Lead

Deeva, despite being the only actual father on the team, does not in any way put any onus on us to do the straight and narrow. Instead, he regularly encourages us to embrace dynamic, passionate attitudes towards everything and similarly incorporates the same attitudes into his visual designs. Neither time nor responsibility has slowed him down, and Deeva’s stunning, high-quality visuals and content are matched only by his speed.

With a prior education in product design, he also often joins the conceptual team in brainstorming; with previous experience as creative director in other organisations, he additionally leads marketing and branding efforts within the team.

In his off time, Deeva enjoys gardening, annoying his wife and children, and writing comics.

Zhang Xuezhi

Electronics Engineer

Xuezhi is a recent graduate from the EPD programme in SUTD and has a habit of tinkering with anything we give him. His sense of straightforwardness, willingness to explore strange ideas, and can-do attitude make him a star with the tech team, where he shines in robotics.

His approachability, presence, and initiative have pushed our projects to the next level on top of what existing team members have built, and he continues to astound us with his adaptability to projects.

In his free time, Xuezhi enjoys good food in Singapore and is awaiting results for a Master’s programme in advanced electronics.

Tai Jing Yu

Electronics Engineer

Jing Yu rounds out the tech team with a ninja-like quietness and an equally terrifying intensity in his work. His steady learning, completion rate, and contributions ensure that projects are finished well and on time. An EPD graduate from SUTD, his fondness for interesting projects is easily seen, and he has an eagerness to further his learning and gain more experience in the field.

With high expectations of himself and his teammates, Jing Yu’s track record has been one of excellence in execution. When possible, he enjoys playing badminton – a longtime hobby of his.

Tan Zai Xuan

All-in-One Engineering Intern

Zai Xuan came back after his interview to drop off a laser-cut namecard, and we made the instant decision to offer the position to him because we love extra people.

He has been an incredible asset to our team, assisting in conceptualisation for client projects, creating new assets for us to use, and working in almost every department we have and across a wide variety of projects. He has also set some things on fire, but we don’t begrudge anyone that around here.

Zai Xuan is a DJ, and is one of the most kindhearted and open people we know too, dedicating his free time to helping others in need through various social efforts he participates in.

Daniel Foo Jun Wei

Design Intern

Jun Wei is our design intern here and is currently the youngest person on the team. With a background in mechanical engineering and a minor in business management, he hopes to sharpen his skills and dive deep into industrial design and creative media, taking every opportunity and turning it into a learning experience. As an aspiring entrepreneur, Jun Wei thrives in an agile, multi-disciplinary environment like ADI where ideas can be realised by creating prototypes, giving him the opportunity to innovate and apply the design thinking process.

Jun Wei is a purpose driven individual who will always be there to assist in any task needed by the team in all aspects be it 3D printing, silicone moulding, laser cutting, photography, documentation and even air brush painting.

In his spare time, Jun Wei likes to play the guitar, work on personal projects and browse through Carousell for good deals.

Truman Ng Jia Jun

Tech Intern

Truman is currently pursuing a degree in Mechanical Engineering (Mechatronics stream) in NTU, and is our current tech intern.

Although his experience is heavily mechanical, he enjoys the challenge presented by the electronics-focused tech team, understanding that it will help him moving forward in cybersecurity, which he is interested in pursuing.
