Awards & Testimonials

“Imantha Ahangama was an outstanding MSc student under my supervision at University of Moratuwa, where he excelled in his research in the domain of Eco-Sustainable Informatics. His ability to grasp complex concepts in deep learning and multimodal data analysis, combined with strong analytical reasoning, led to innovative solutions that pushed the project's boundaries. He lead publication in a prestigious Q1-ranked journal: "Explainable Image Segmentation for Spatio-Temporal and Multivariate Image Data in Precipitation Nowcasting", a testament to his mastery of deep learning, multimodal analysis, and explainable AI techniques that advanced weather data screening. What impressed me most was Imantha's unwavering motivation and perseverance through research challenges. With these qualities, he won the "Best Solution Addressing National Disasters" award at the National ICT Awards - NBQSA 2024, delivering high-quality, publishable results. Wishing you continued success and groundbreaking achievements ahead!”

“I had the pleasure of working closely with Imantha at CML Insight, and I can confidently say he is an exceptional Engineering Lead. Imantha was my go-to partner on every project. I relied on his deep technical expertise, fast turnaround on questions, and clear explanations of data pipelines and system design. He set a high bar for engineering rigor by establishing documented best practices across model development, progress tracking, deployment, and monitoring, all while moving quickly and delivering real business impact. Despite working across time zones and countries, collaboration was seamless thanks to his consistent availability during overlapping hours. As a leader, Imantha is thoughtful, decisive, and highly effective. I've seen him work with more junior engineers with clarity and empathy, fostering a strong culture of ownership and continuous learning. He balances short-term execution with long-term architectural thinking, and his guidance consistently elevated both the technical quality of our projects and the confidence of the team delivering them. What truly sets Imantha apart is his ability to bridge data science, engineering, and product. He asks the right questions, constructively challenges assumptions, and ensures that all proposed solutions are not only technically sound but also aligned with user needs and business goals. Any organization would be fortunate to have Imantha leading their machine learning efforts. I would gladly work with him again and recommend him without hesitation.”

“I got the opportunity to work with Imantha in couple of projects in IFS Aerospace and Defense, and I can assure that he is a highly dedicated and committed colleague. He has the ability to look at problems from a different perspective and share better solutions to them. I have seen his full dedication to the tasks that he receive and he completes them on time. Within the short period of working together, he became the person whom I assign critical tasks to, since I knew he would get it done in the best possible way and on time. I highly recommend Imantha to any software development team.”

“Imantha joined to my team as a fresh graduate. As the team leader of his first development team, Imantha was recognized as a very dynamic, responsible, and talented person. Whatever the challenge task assigned to him, he accepted it very positive manner and completed very efficiently with good quality as well. Even though he was a fresh graduate, he managed to complete his work with less guidance. So, I was very confident when assigning tasks to him. He is a very good team player as well. He always willing to help the team-mates and share the knowledge. I noticed his analytical skills through out the work we did together. He is capable of thinking, different solutions according to the situation. He is a very friendly and respectable person too. With the above qualities, I have no hesitation to recommend Imantha”

“Imantha was a friendly teammate with a good spirit. Fast learner and really competent with his work. He has new innovative ideas and could analyze, solve many problems by his own. Not as a fresh graduate he always showed his talents and competencies as an experienced individual. As a mentor and a senior colleague I just gave him proper guidance and he always took the responsibility and drove the work he was assigned. Due to above reasons I can recommend Imantha for anyone without any doubt.”
