Leading products to success
Leadership is the discipline underneath every product I build. It aligns people, timelines, technical constraints, and strategy toward one clear outcome.
These experiences come from building my own startup as much as from my current work in the industry. My product work spans customer experiences in Sri Lanka, Australia, Bangladesh, and Fiji, across SaaS products, inventory management software, booking and schedule management platforms, AI first solutions, and Communications as a Service products. Alongside product and project management, I have built communities around API based development, AI based development, astronomy, hackathons, workshops, and lectures while mentoring startups and upcoming entrepreneurs on solutioning and ideation.

“Together, Towards a better era”
// beyond the product
An astronomer at heart
Astronomy is the longest-running thread in my life. It began at Nalanda College, where the astronomical society turned a curiosity about the night sky into a discipline: observation camps, telescope sessions, star charts, and the patient kind of looking that only rewards you after hours under a dark sky. That patience became my default setting for research, engineering, and product work alike.
My core expertise is in observational astronomy and research through the Nalanda College Alumni Astronomical Society, where I currently serve as Assistant Secretary. Before that I was President of the Nalanda College Astronomical Society and led its quiz team, hunting constellations on paper as intensely as we did through an eyepiece.
What keeps me hooked is passing it on. Through Astro Minds I lecture everyone from Grade 5 students to undergraduates on astronomy, astrophysics, cosmology, astrophotography, and practical observation, because the fastest way to understand the universe more deeply is to teach it to someone seeing it clearly for the first time.
