I've contributed Java and Go routing capabilities to WSO2 API Manager and WSO2 API Platform, including LLM, semantic, and multi-provider routing for API integrations.

During my WSO2 internship, I also developed and tested the Ballerina PayPal Connector, contributed UI components to the Documentation Assistant, resolved an AWS Bedrock routing issue, and supported release testing.

Since 2022, I've delivered 50+ websites and software projects for international clients through freelance work. I build Next.js and Node.js applications, responsive business websites, e-commerce and rental platforms, and custom WordPress plugins and themes.

I'm currently pursuing a BEng (Hons) in Software Engineering while remotely maintaining websites for USA and UK companies through troubleshooting, SEO, performance improvements, and content updates.
