What I'm looking for

I’m looking for a role where I can build and support web/cloud solutions and contribute accurate AI training data. I want a team that values high-quality work, fast learning, and cross-functional collaboration to deliver user-focused outcomes.

I’m an enthusiastic IT professional with a strong foundation in software development, technical support, and data annotation. I deliver reliable, user-focused solutions while maintaining high accuracy and adapting quickly across projects.

As a Software Developer at Hytel, I configure branch protection and repository policies, develop and deploy serverless cloud functions with Firebase and Google Cloud Platform (GCP), and integrate external live services via APIs and webhooks. I also build efficient frontend state management using TanStack Query and work with Firestore NoSQL for scalable real-time data storage, alongside contributing to AI-powered solutions using Vertex AI and GCP services.

Across internships and remote roles, I’ve supported end-users through troubleshooting, run SQL queries to extract and analyze operational data, and prepared and annotated AI training data with structured guidelines (including bounding box, image/video labeling, and audio transcription). I enjoy collaborating with cross-functional teams to ship improvements on schedule.
