Samitha Nanayakkara
Senior Technical Lead | AI, Web & Mobile Innovation
Strategic Clarity. Evolutionary Architecture.
I bridge the gap between abstract vision and concrete execution. My focus is on architecting systems for scale, optimizing technical economics, and multiplying engineering capacity through mentorship and culture.
