Architecting scalable multi-tenant SaaS platforms — with Next.js, React, TypeScript, and Nx Monorepos.
About
A bit about who I am
I'm a proactive software engineer from Colombo, Sri Lanka, with 3.5+ years of industry experience specializing in scalable Next.js, React, and Node.js ecosystems. I architect multi-tenant SaaS platforms, optimize high-traffic web performance to 95+ Lighthouse scores, and engineer complex Nx Monorepos.
From the KAIONEX ERP ecosystem at Techloom.ai to AXA Switzerland's unified component library at soosap, I've shipped 15+ production applications and contributed 2,700+ commits on GitHub in the last year. A collaborative problem-solver with a strong foundation in TypeScript and open-source contribution.
Currently pursuing a BEng (Hons.) in Software Engineering at the University of Westminster (IIT) while serving as Webmaster for the IEEE Computational Intelligence Society and volunteering with the Yarl IT Hub tech community in Jaffna.
