Applied AI & Interactive Systems Researcher
Building real-world AI and interactive systems with a focus on agentic workflows and human–AI interaction. My work involves designing and evaluating deployed AI tools and interactive systems, using behavioral data and controlled experiments to study user understanding, trust, and decision-making.
Research Interests
Human-AI Interaction
Investigating mechanisms for trust and clarity in collaborative loops between humans and autonomous agents.
Agentic AI
Developing evaluation-driven agent workflows for multi-step reasoning and complex tool interaction.
Interactive/XR Systems
Building experimental platforms that leverage spatial computing for new forms of human-computer synergy.
Behavioral Data
User-centric evaluation through the analysis of interaction logs and physiological behavioral signals.
Research Outputs & In-Progress Work
Speech Analysis API (IELTS-Aligned)
English proficiency assessment system
Research Motivation
Determining if automated speech analysis can provide rapid, reliable assessment of English fluency and pronunciation.
System Built
Built with Python, Whisper, Wav2Vec and FastAPI. Provides band-style scores across fluency, pronunciation, vocabulary, and grammar dimensions.
Evaluation / Data
Deployed as production SaaS on RapidAPI
Key Insight
"Automated assessment alignment with IELTS standards enables rapid proficiency evaluation without human raters."
WhatsApp AI Customer Support System
Automated customer service chatbot
Research Motivation
Testing whether conversational AI can automate customer support with intelligent issue categorization and response generation.
System Built
AI-powered WhatsApp chatbot that converses with customers, collects complaints, and uses OpenAI to categorize issues automatically using n8n workflow automation.
Evaluation / Data
Deployed for real customer support with real-time categorization metrics
Key Insight
"AI-driven categorization reduces manual triage time while maintaining customer satisfaction through natural conversation."

VR Projects
Immersive experiences with spatial input
Research Motivation
Exploring immersive VR experiences that combine audio-reactive environments and real-world mechanical input for novel interaction paradigms.
System Built
Created a music VR project with audio reactivity. Co-created a surfing VR game that accepted input from a mechanical surfboard, translating physical movement into in-game navigation and actions.
Evaluation / Data
Demonstrated proof-of-concept for peripheral device integration with VR and validated immersive gameplay through playtest feedback
Key Insight
"Mechanical input devices enhance immersion by creating direct physical-to-digital feedback loops, improving user engagement in VR experiences."

AI Book Translator
Multi-language document translation system
Research Motivation
Designing semantic translation pipelines with quality validation across multiple languages.
System Built
Processes PDFs page-by-page, uses Claude API for semantic translation, and OpenAI as evaluator for quality validation. Generates four DOCX outputs in different languages while preserving page structure.
Evaluation / Data
Maintains document structure and numbering across all output languages with semantic accuracy validation
Key Insight
"Multi-stage translation pipeline with AI-driven quality assurance enables rapid document localization at scale."

Mafia Marksman
Mobile game - 100k+ downloads
Research Motivation
Investigating how data-driven gameplay design and A/B testing can optimize player retention and monetization.
System Built
Mobile cover-shooter game with analytics integration for gameplay metrics, A/B testing framework, and real-time balance iteration.
Evaluation / Data
FTUE optimization, retention metrics (D1/D7/D14), engagement and monetization analysis across player cohorts
Key Insight
"Analytics-driven game design improved D7 retention by 18% and ARPU by 22% through iterative feature balancing."
