Founder & CEO · Full-stack software engineer
12+ yrs industrial engineeringBSc (Hons) Software EngineeringAWS AI & ML Scholar 2026
I'm the Founder & CEO of Athena Xtreme Solutions (Pvt) Ltd, a Sri Lanka-based software company building practical, scalable digital systems for businesses — SaaS platforms, ERP and POS systems, web and mobile apps, and business automation.
Before software, I spent 12+ years in manufacturing and industrial engineering at Hirdaramani, MAS Holdings and Classic Fashion (Jordan) — line balancing, SMV analysis, productivity and process optimisation. That's why I look at software from the operations floor, not just the code.
My flagship, AthenaX Elite Serve, runs restaurants, bars and hotels on one database: POS with kitchen and bar displays, bar control by the peg, inventory and recipe costing, hotel PMS, HR and payroll — built for LKR, LankaQR, Sinhala receipts and WhatsApp.

What I'm building next
Every product below is a real codebase under active development — multi-tenant, typed end-to-end and built for a specific industry.
Industries
Built for how real industries operate
Each product starts with operators on the floor — then turns their workflow into a multi-tenant platform.
Tech Stack
The stack in production
The same core stack powers every Athena Xtreme product — real-time Convex, Postgres systems of record, and AI where it earns its place.

The playbook
From the shop floor to production SaaS
The same four steps behind every Athena Xtreme product.
1
Week 1
Sit with operators
Every product starts on the floor — at the cashier counter, the bar, the workshop. Real workflows, not assumptions.
01
2
Week 2
Model the business
Tenancy boundaries, roles, money flows and audit trails designed first — Postgres for truth, Convex for real-time.
02
3
Weeks 3–N
Ship in weekly releases
Small, frequent releases straight to production, typed end-to-end and tested on the flows that touch money.

Ongoing
Operate & improve
I run what I build: monitoring, support, backups and a roadmap driven by the businesses using it every day.
