Haoze combines AI research with hands-on product development, including system architecture, implementation, technical-team leadership, and LLM prompt engineering refined through domain-expert feedback. Haoze’s work includes an event-driven proactive multimodal assistant for multiple business domains, for which Haoze owned the pipeline from a 158-hour training corpus through training and evaluation the work improved turn-taking F1 by 5% and reduced inference costs by approximately 5×. Haoze also developed a real-time AI speech-therapy platform with therapist collaboration and phoneme-level feedback, and co-developed Mnemosyne, a graph-based long-term memory architecture for edge LLMs. In computer vision, Haoze improved surgical-video classification to 93.8% average accuracy on previously unseen real-world videos, a 5.6-percentage-point gain. Earlier roles at Deloitte and CITIC Securities added experience in consulting, investment-banking research support, SQL-based data workflows, data-quality validation, and reconciliation. Haoze holds a master’s degree in Systems Engineering from the University of Pennsylvania and a Bachelor of Science in Chemistry from National Sun Yat-Sen University. ## Services - Oracle SQL Developer - Convolutional Neural Networks \(CNN\) - Machine Learning - NoSQL - Microsoft Power BI - Python \(Programming Language\) - Java - MySQL - Overleaf ## Highlights - Built an event-driven proactive multimodal assistant across multiple business domains at Kaliber Labs Inc. - Owned the proactive-assistant pipeline from preparation of a 158-hour training corpus through model training and evaluation. - Improved turn-taking F1 by 5% for the proactive multimodal assistant while reducing inference costs by approximately 5×. - Developed a real-time AI speech-therapy platform combining voice activity detection, parallel text and phoneme recognition, prosody analysis, emotion-aware dialogue, adaptive pronunciation exercises, text-to-speech, persistent sessions, and automated clinical reports. - Built real-time phoneme-level feedback into the speech-therapy platform using AI and LLMs in collaboration with therapists. - Co-developed Mnemosyne, a graph-based, human-inspired long-term memory architecture for edge LLMs with temporal decay, memory reinforcement, redundancy filtering, pruning, and probabilistic recall. - Improved a surgical-video classification system to 93.8% average accuracy on previously unseen real-world videos, a 5.6-percentage-point improvement. - Supported a Deloitte client’s business-intelligence migration by developing SQL-based ETL and reporting workflows. - Produced end-to-end data-lineage documentation and source-to-target mappings across Finance, Procurement, and Logistics domains at Deloitte. - Validated data warehouse and data mart quality for fact and dimension tables through full-load versus monthly-partition checks and cross-business-type value validation. - Authored structured test reports, performed cross-platform reconciliation, and conducted root-cause analysis on discrepancies to improve pipeline accuracy and reporting reliability at Deloitte. - Worked as an Investment Banking Assistant Research Analyst at CITIC Securities. - Applies LLM prompt engineering and iteration based on domain-expert feedback. - Combines AI research with AI product development, high-level system architecture, hands-on implementation, and technical-team leadership. ## Experience - **AI Researcher at Kaliber Labs Inc.** (2024-07-01–present) — Researching and building production-oriented multimodal AI systems across conversational intelligence, speech • technology, long-term memory, and computer vision. • Built an event-driven proactive multimodal assistant across multiple business domains. • Owned the pipeline from preparing a 158-hour training corpus through model training and evaluation, improving turn-taking F1 by 5% while reducing inference costs by approximately 5×. • Developed a real-time AI speech-therapy platform combining voice activity detection, parallel text and phoneme recognition, prosody analysis, emotion-aware dialogue, adaptive pronunciation exercises, text-to-speech, persistent sessions, and automated clinical reports. • Co-developed Mnemosyne, a graph-based, human-inspired long-term memory architecture for edge LLMs. • The system incorporates temporal decay, memory reinforcement, redundancy filtering, pruning, and probabilistic recall. • Improved a surgical-video classification system to 93.8% average ac - **Consulting Analyst at Deloitte** (2023-07-01–2023-08-01) — Supported a client business-intelligence migration by developing SQL-based ETL and reporting workflows and producing end-to-end data lineage documentation \(source-to-target mappings\) across Finance, Procurement, and Logistics domains • Validated data warehouse and data mart quality for fact and dimension tables through multi-scenario • testing \(full-load versus monthly partition checks, cross-business-type value validation\), ensuring consistency in both record volume and business metrics • Authored structured test reports and performed cross-platform reconciliation, conducting root-cause • analysis on discrepancies to improve pipeline accuracy and reporting reliability. - **Investment Banking Assistant Research Analyst at CITIC Securities** (2023-05-01–2023-07-01) ## Education - Master's degree, Systems Engineering — University of Pennsylvania (2022-08-01–2024-06-01) - Bachelor of Science - BS, Chemistry — National Sun Yat-Sen University (2018-09-01–2022-06-01) ## FAQ ### What does Haoze do?
