Hi, welcome to my portfolio.
First Class Computer Science and Engineering graduate with hands-on software, DevOps, hardware, and cybersecurity experience, now aiming that versatility toward security engineering.
A jack of all trades trying to master one ~
A practical walkthrough of building Huggy, a portfolio chatbot designed around free-tier limits. The article covers making a static portfolio feel conversational without exposing API keys, running a controlled RAG-backed assistant, and using Hugging Face, Groq, Cloudflare, and careful rate limiting to avoid surprise cloud bills.
A reflection on the engineering discipline Rust teaches, even outside Rust code. The article looks at how thinking like a Rust developer, and studying the tradeoffs made by Rust’s own designers, can sharpen principles around explicit contracts, boundaries, failure, guarantees, and long-term software design.
A curious, hands-on experiment with compound scaling: taking the EfficientNet idea of balancing depth, width, and resolution, then trying it on the lightweight ShuffleNetV2b architecture. An article reading like lab notebook, moving from the theory behind CNN scaling into implementation, tuning, and what the results suggest.
A practical walkthrough for turning GitHub Actions into a secure deployment pipeline for web hosting. The article connects Docker, AWS EC2, Cloudflare origin certificates, and repository secrets into a repeatable flow, with the kind of careful notes that come from actually building and debugging the setup.
A grounded guide to hosting personal web apps when static hosting is not quite enough. It covers buying a domain, connecting Namecheap and Cloudflare, setting up an AWS instance, keeping HTTPS in the loop, and using Cloudflare Workers for routing, all with a friendly reminder to keep an eye on cost and security.
Reference implementations written to battle-test API-based WSO2 Financial Services Accelerator extensions.
Redesigned the WSO2 FS Accelerator consent authorization module to support deeper Open Banking customization, especially for NextGenPSD2 use cases.
University exam registration with cloud deployment and GitHub Actions CI/CD.
A simple high performance pipelined log processor written in Rust.
RAG-based Sinhala chatbot using LLMs, Transformers, and QLoRA fine-tuning.
Verilog game with VGA output on the DE2-115 development board.
Contributed to automation, site reliability, observability, and consumer products at Virtual System Solutions.
