What I'm looking for

I'm looking to build AI-native tooling, RAG knowledge systems, and secure production integrations where I can combine hands-on engineering, testing, technical governance, and direct customer collaboration.

I've integrated WeKnora across organizational wikis to create structured RAG knowledge bases with RBAC, workspace separation, audit trails, delta updates, and model evaluation.

I built a Claude plugin marketplace for development, QA, and DBA workflows, supported by MCP servers and a senior-review process for new skills. I also created a cross-platform .NET MCP server that exposes read-only database schema metadata to AI coding assistants over stdio JSON-RPC.

At HCL Technologies Lanka, I led development of a vehicle leasing platform, delivering complex leasing calculations, technical POCs, and client-aligned solutions while managing a small team. Earlier at hSenid Business Solutions, I delivered SOAP and REST integrations across .NET and PHP and helped strengthen security processes supporting ISO 27001 certification.

I've also shipped cloud-native full-stack products on Azure, including a travel agency management system that improved customer-management efficiency by 90%. My work is grounded in TDD, E2E testing, containerized CI/CD, direct client collaboration, and practical AI-assisted development.
