Cartoon avatar of Nivin Madawalage

I'm a software engineer with a strong interest in AI and cloud technologies. I currently build AI-driven platform applications at H2O.ai with React, Go and Python, and run them on AWS and Kubernetes. I like combining analytical thinking with creative problem-solving to design systems that are scalable, intelligent and genuinely useful in the real world.

A selection of my recent work

Cuff Cloud

A multi-tenant SaaS practice-management platform for medical clinics covering appointments, patients, prescriptions, inventory and billing. Each clinic signs up and gets its own subdomain, provisioned automatically.

Schema-per-tenant isolation
Every clinic lives in its own PostgreSQL schema, resolved from the request host
Self-serve billing
Stripe checkout through a payment adapter with verified webhooks
Automated provisioning
Background jobs set up each new tenant on its own subdomain
Plan-based access
Per-plan feature flags and RBAC, with a startup check that blocks any unprotected API route
