I am an AI Data Trainer and software engineer with 3+ years focused on data labelling, model training, and ML tooling. I combine hands-on annotation expertise with full-stack development experience to deliver high-quality datasets and tools that improve model performance.

I have annotated and reviewed large-scale image, text, and video datasets, contributed to computer vision (detection, segmentation, classification) and NLP tasks, and participated in RLHF for conversational systems. I have consistently achieved over 98% accuracy in annotation consistency through rigorous QA and guideline refinement.

On the engineering side, I have built scalable web and SaaS applications using the MERN stack and AWS, designed microservices with Docker and EC2, and optimized backend architecture to reduce API latency. I’ve also developed internal dashboards and automated data workflows using React, Node.js, AWS Lambda, GitHub Actions, and S3.

I seek roles where I can bridge data annotation operations and ML engineering—improving annotation quality, building annotation/management tools, and contributing to model fine-tuning and evaluation pipelines.
