What I'm looking for

I'm looking for opportunities where I can prepare high-quality AI training data, apply detailed annotation standards, and grow my technical background in software development, databases, and AI-related computing.

At Innodata Lanka, I prepared AI training data by annotating image, audio, and video content according to detailed project guidelines.

I review multimedia data, label objects, actions, events, and information, and maintain structured, consistent datasets that meet project quality standards.

I've participated in quality reviews, corrected annotations through feedback, clarified ambiguous cases with project teams, and managed workloads independently to meet deadlines and daily targets.

Alongside annotation work, I've built a PC–mobile file-sharing system with Electron, React.js, React Native, Node.js, and Socket.IO, and contributed to Guidely, a mentorship platform built with Next.js, NestJS, and MongoDB.
