About

I’m Molla Safayet Hossan, specializing in AI data annotation, RLHF evaluation, and Bengali language model assessment (accuracy, grammar, tone, and cultural nuance).
​Proven expertise in spatial feature annotation (CVAT, bounding boxes, polygon segmentation, vector digitizing), data collection tools (KoboToolbox/XLSForm), and AI response quality assurance (QA). Skilled in auditing AI outputs against project rubrics, identifying edge cases/ambiguities, and providing clear, actionable written feedback to improve model performance.
​I have hands-on experience in AI data annotation, evaluation, and quality assurance, alongside academic backgrounds in Urban & Regional Planning (BURP) and an MBA in Human Resource Management.
​My evaluation work includes testing LLM outputs for accuracy, tone, safety, and guideline adherence across both English and Bengali languages. I regularly evaluate response quality, spot subtle factual or logical inconsistencies, and write clear, constructive feedback to help refine AI responses.
​Additionally, I have practical experience with spatial data annotation and labeling tools like CVAT, bounding boxes, polygon segmentation, and mobile data collection via KoboToolbox/XLSForm. I am comfortable working with complex guidelines, managing edge cases, and delivering consistent quality under project deadlines.
