How we know each other
Mentored me for about a year at Saizen Acuity on production systems across web architecture, data engineering and applied AI, under real delivery deadlines rather than classroom simulations.

What they taught me“Look at the trade-offs of the entire system.”
Advisor at Saizen Acuity, where we build together. He relies every day on the post-call analysis engine I built, which turns his recorded conversations into structured tasks.

What they taught me“Build systems for resilience, not just optimality.”
To Whom It May Concern, I am a senior technology executive with experience founding and exiting AI businesses, leading large global engineering organizations, and advising on applied AI across industry, academia, and public policy. I am formally recognized by professional computing bodies and have published and testified on AI at national level. It is in this professional capacity that I have mentored Sankitha Kirindu for approximately one year at Saizen Acuity. During this time, I have worked closely with Sankitha on production systems spanning web architecture, data engineering, and applied AI. Because this work is conducted under real delivery, time, and reliability constraints rather than academic simulation, it has given me a clear view into his technical ability, judgment, and character under pressure. Sankitha is unusually systems-oriented for a student at his stage. He does not treat problems as isolated technical exercises, but as interconnected systems...

“Sankitha combines speed, humility, resilience, and technical depth in a way that is uncommon.”
Dear Admissions Committee, My name is Aamar Hussain. I currently serve as Global Strategic Generative AI Tech Lead for GSI and SI Partners at Google, I am an advisor at Saizen Acuity, and I am the founder of Horizon AI Consulting and PredictStream.ai. Prior to this, I held the role of Director of Azure Data and AI Cloud Solutions Architects and Engineering at Microsoft. Over more than twenty five years across Google, Microsoft, and global enterprises, my work has focused on helping organizations move beyond the hype of emerging technology and turn complex, messy data into adaptive, automated insights that deliver real business value. Equally important to me is how people grow inside that process. I care deeply about building psychological safety, recognizing individuals as human first, and empowering teams to think clearly, learn quickly, and act with confidence. It is from this perspective that I write in strong support of Sankitha Kirindu. What stands out to me...
Letter 03Academic · Ananda College
“Sankitha stands out clearly as our strongest recommendation for the 2026 admissions cycle.”
To Whom It May Concern, I write in my capacity as the School Counsellor of Ananda College, Colombo, one of Sri Lanka’s most venerable highest ranking competitive public institutions, entrusted with the academic and moral formation of over 6700 students under a faculty exceeding 300 teachers. In such an environment, where excellence is both expected and relentlessly tested, discernment becomes a professional duty. Praise must be earned, not offered lightly. It is from this position of custodial responsibility that I present Sankitha Kirindu. Ananda College admits only the most capable students in the country through the Grade 5 National Scholarship Examination, which all students in Sri Lanka following the local curriculum sit for at the age 10. Sankitha’s trajectory, however, is noteworthy even within this selective context. He entered through Grade 1 admissions on the basis of early academic promise and linguistic ability, yet by Grade 5 had outperformed...

Susantha Saviour
Further Mathematics & Mathematics Teacher
Received via WhatsApp
Here, as his teacher, I coached him for the Cambridge International A Level examinations in Mathematics and Further Mathematics. In this recommendation letter, I emphasize his particular strength in Further Mathematics, which goes beyond the traditional Mathematics syllabus. Further Mathematics is not a subject that rewards speed or surface intelligence. It is widely regarded as the most demanding subject of the advanced level curriculum around the world, covering multiple years of university-level math, taken by a small minority of math students and mastered by fewer still. In most years, only an extremely small number of candidates in the entire country achieve the A* grade. It requires not only technical fluency but endurance, abstraction, and the willingness to remain with an idea long after comfort has ended. Having taught this subject for more than three decades, I have learned that genuine success in Further Mathematics is never accidental. It is earned...

Ruwan Iddamalgoda
Advanced Level CS Instructor // Cambridge Most Influential Teacher
Received via WhatsApp
To Whom It May Concern, I’m Ruwan Iddamalgoda, I have taught Advanced Level Computer Science for decades, including work alongside Arthur C. Clarke. I was awarded the Cambridge Most Influential Teacher in the world in 2017 and served as The Head of Studies at Whycherley International School, one of Sri Lanka’s leading international schools, where I was part of the academic leadership for over 25 years. I am careful with recommendations because strong results alone do not predict strong engineers. Sankitha Kirindu earned this letter through sustained, observable behavior over more than a year of close academic work. Even before results such as Top in Country in Computer Science and all A star grades later confirmed his ability, it was already clear to me that he was operating at an exceptional level. What first stood out was his intellectual stamina. Sankitha does not study reactively. He executes. Early in our course, he informed me that he had completed every variant...

“Without hesitation, I can say he is one of the most brilliant students I have taught in my entire teaching career.”
To Whom It May Concern, My name is Dimuth Wanigathunga. I hold a National Diploma in Teaching (Mathematics) and a Diploma in English, and I have served as an academic staff member at Ananda College. I have over two decades of teaching experience, including work in three leading government schools, and during this time I have taught students of very different abilities. Please observe that this long experience has made me careful with recommendations. I do not praise quickly. I am writing this letter to recommend my student, Sankitha Kirindu, with complete confidence. I taught him continuously from Grade 7 to Grade 11, from the age of 12 until 17, and over this long period I was able to see his development very closely, step by step. There were moments when he struggled, and moments when he doubted himself, but he did not rush. Without hesitation, I can say he is one of the most brilliant students I have taught in my entire teaching career. He joined my private class at...
