Meet the founder
Lahiru Wijesuriya
Founder & AI Systems Architect
I've spent 5+ years building enterprise-scale AWS infrastructure — Kubernetes clusters, CI/CD pipelines, and platform engineering — and I still do. SmoothSailor is where that rigour meets growing businesses: Shopify engineering pipelines, n8n and Zapier automation, booking platforms, AI lead generation, and hardening the home-grown apps businesses run on. Each side makes me better at the other — enterprise discipline for small business, small-business speed for enterprise.
One engineer, one relationship. You work directly with the person building your systems — no handoffs, no rotating teams, no layers of project managers between you and the work.
How we work
Enterprise quality
The same engineering standards used for Fortune 500 infrastructure, applied to your small business workflows.
Weeks, not months
Most engagements deliver results in 2-4 weeks. Quick wins first, then we expand as your confidence grows.
Ongoing support
We monitor, maintain, and optimise your systems as your business grows. If something breaks, we fix it — often before you notice.
