"I believe the best technology is invisible — it just works, beautifully, at scale."
At Central Group Thailand, I lead a team of 6 engineers building production AI systems: Strainer (personalization for 10M+ users), Tops Chefbot (Thailand's first AI recipe assistant with 50K+ product integration), and Feed Fusion (cross-channel marketing automation). Experienced in defining AI architecture strategy on GCP and AWS.
Led a team of 6 engineers designing and implementing AI systems and data engineering solutions across Central Group's major retail brands — PowerBuy, Supersports, Tops, and Central Department Store.
"Working with Aju John has been a pleasure. As a leader within the MarTech Org, Aju brings deep technical expertise and an unwavering proactive spirit. He's been an incredible partner to the digital marketing team, has never turned away from a challenge and has many times suggested ways and solutions to our problems. I would argue that Aju and the MarTech team are some of the best engineers I have ever worked with."
"It was a pleasure working with Aju on several AI and LLM projects. He successfully integrated AI into our search functionality, leading to a significant uplift in search performance. Beyond strong technical expertise, Aju understands business needs and translates them into effective solutions with clear communication and a collaborative approach."
"I've had opportunities to work with Aju on so many projects and have learned so much from him. His combination of skills to manage a highly efficient team and drive solutions is unmatched. He is highly skilled, efficient, and always delivers high-quality work. I can 100% guarantee he will be a highly valuable member to any team."
"He is not only technically exceptional but also maintains a very lively work environment. We worked on a technically challenging Digital Pathology ecosystem for 18+ months. Though brought in as a Senior Developer, I would rate him as a UI Architect. He was a go-to person for technical issues for many team members. Great asset anywhere he works."
"Quick learner and a total performer. I was particularly impressed by Aju's ability to maintain performance under pressure — a skill that often takes years to develop, but which seemed to come perfectly naturally to him. Aju would be an asset to any team."
Open to senior Data & AI Engineering roles across the SEA region. Whether you have a position, a project, or just want to talk about the future of AI — I'd love to connect.
