Full-Stack Developer · Sri Lanka
You bring the problem. I ship the solution, from first line of code to live on the cloud.
(01) — About
I'm a full-stack developer building robust, scalable applications with the MERN stack, Laravel and native Android. I deploy on AWS with CI/CD pipelines, manage MongoDB on production servers, and build and maintain WordPress sites on AWS and cPanel hosting.
I care about performance and user experience, and about shipping products that work as well as they look.
(02) — Selected work
Production platforms, published mobile software and applied AI—selected for depth, ownership and real-world constraints.
Digitizing marketplace & production platform
A three-sided platform where digitizers bid on customer artwork with stitch-count estimates and admins choose the best balance of cost, quality and turnaround. Every order moves through production, revisions, PayPal payment and payment-gated file delivery. All of it was migrated from a legacy system with a different architecture.
Centralized order operations hub
A centralized internal system for the Broward County Transit uniform program. Orders from bulk-scanned documents, on-site operator entry and the existing customer portal merge into one validated queue. From there they move through dispatch, accounting, fulfilment and signed handover, while employee and order data stay in sync with the portal.
QR pet recovery & e-commerce platform
A pet-management and e-commerce platform built around QR tags. Owners manage multiple pets and tags in one place. Anyone who finds a lost pet can scan its tag to alert the owner by SMS and email with a map link, and the same platform sells the tags through PayHere.
Cross-platform commerce app · iOS & Android
A React Native and Expo app that connects to Global Trading, Inc.'s existing commerce system. Customers can browse products and services, place and pay for orders, upload artwork and track order history from their phone. It is published on both the App Store and Google Play.
AI-assisted cognitive wellbeing app · BSc final project
A CBT-inspired reflection app built as three services: an Expo client, an Express and Prisma API, and a FastAPI NLP service. It highlights nine types of cognitive distortion in the user's own words, recalls recurring thoughts through pgvector semantic memory and handles crisis signals with a fail-safe design.

DevOps3 min readReact on S3 and CloudFront, Express on EC2 behind Nginx and PM2, and a GitHub Actions workflow that ships both on every push to main.
The checklist I follow when a client's site starts redirecting to spam: contain, find the entry point, rebuild from clean sources, then harden.
Signing checkouts on the server, verifying the notify callback properly, and why the redirect back to your site should never mark an order as paid.
