What I'm looking for

I'm looking for a remote role where I can apply my experience in AI training, data annotation, and quality assurance. I’m interested in projects involving localization, conversational AI, or computer vision. I value clear guidelines, collaboration, and opportunities to contribute to high-quality, real-world AI systems.

I am a results-driven AI Data Annotation and Quality Assurance Specialist with 4+ years of experience across NLP, computer vision, speech, and geospatial data projects. Currently, I lead a team of 50+ remote professionals delivering large-scale multilingual AI training and evaluation, having improved project delivery speed by 25% and reduced annotation inconsistencies by over 18% through process optimization and quality SOP implementation.

My contributions span over 30 AI projects, where I’ve conducted RLHF-based LLM evaluation, multilingual prompt-response alignment, and advanced QA. In Community Alignment - Evaluation v2, I led qualitative review strategies that improved ethical model compliance by 22%. During Omni Hindi v2, I ensured culturally sensitive evaluation for Hindi-English code-mixed outputs, improving regional response accuracy by 19%.

In voice and speech-based projects like Realtime Voices (English/Hindi) and RealTalk_G_V2_Hindi, my team and I collected and QA-verified over 10,000 utterances, leading to a 20% increase in ASR model clarity and dialect recognition rates. In geospatial projects with OneForma, I labeled over 5,000 satellite imagery samples, contributing to improved routing accuracy for mapping tools by 17%.

For translation and QA efforts in Karimata, Tansy, and Cornelia, I identified and corrected over 1,200 semantic mismatches, reducing translation error rates by 15%. In misinformation evaluation tasks (Cherry V2, Uolo V2), my feedback loops directly supported a 25% reduction in false positive detection by the model. Additionally, my work on projects like Orion, Fireweed, Spearmint, and LLM Voyager included crafting edge-case test prompts and improving alignment accuracy in Hindi and English by 20% through detailed annotation and triage feedback.

I’ve also contributed to real-time user support and AI training in the gaming sector with Ubisoft, helping train chat models that reduced response escalation rates by 30% through improved sentiment and intent detection.

I hold certifications from Salesforce (AI Associate), Google Cloud (Visual AI), and Microsoft/LinkedIn (Generative AI Essentials), and bring strong technical proficiency in Labelbox, Label Studio, Jira, Excel, AutoCAD, and SRT tools. My background in mechanical engineering equips me with structured problem-solving, while my deep hands-on experience in AI training and team leadership makes me well-positioned to scale intelligent systems that are accurate, fair, and effective across global use cases.
