Rui Su
Machine Learning Engineer and PhD candidate at Maynooth University, specialising in real-time ML systems, ensemble prediction, and low-latency algorithm design. Founder & Director of Intonation Labs (Singapore), building production AI systems and SaaS products.
I build production AI systems that work under real-world constraints — latency budgets, cost limits, and reliability requirements. My PhD research at Maynooth University focuses on real-time audio processing and adaptive tuning algorithms, combining self-supervised ML, ensemble prediction, and low-latency signal processing.
In February 2026, I founded Intonation Labs Pte. Ltd. in Singapore, operating a dual-engine model: B2B ML consulting for startups and SMEs, and development of SaaS products including IntonationAI (AI music coaching), IntoMeeting (real-time AI meeting co-pilot), IntoMarketing (AI marketing automation), and IntoBadminton (evidence-led badminton equipment finder).
My path from a B.A. in Psychology at UC Davis to a Computer Science PhD gives me a strong appreciation for human-centred design in technical systems. I am bilingual in English and Mandarin Chinese, and have lived and worked across three continents.

Instant Harmonies
PhD ResearchProduction-grade browser-native system for real-time music analysis and adaptive just intonation tuning. Combines ensemble ML prediction with low-latency audio processing (~1.7 ms median / ~2.2 ms p99 end-to-end latency).
Three research contributions: (1) S-KEY-Symbolic — first self-supervised local key detection for symbolic MIDI, (2) MTS/MPE dual-protocol real-time tuning with hierarchical fallback, (3) BACHI chord-aware JI tuning with 7-limit ratios from 99,251 extracted chord labels.
IntonationAI
LiveAI-powered vocal coaching platform providing personalised, real-time feedback on pitch accuracy, tone, timing, and technique. Uses Vertex AI Gemini 2.0 Flash and Google Speech-to-Text v2 for audio analysis.
IntoMeeting
LiveReal-time AI meeting co-pilot that runs alongside Google Meet or Zoom. Captures meeting audio via streaming transcription, detects client questions, and surfaces RAG-powered answers from the user's knowledge base in real time.
IntoBadminton
LiveEvidence-led badminton equipment finder and review site. A five-step finder captures skill level, discipline, and play style, then returns a ranked shortlist with transparent fit-score reasoning — backed by structured comparison guides with explicit source-authority labelling.
IntoMarketing
In DevelopmentAI-powered marketing automation platform with daily intelligence pipelines, automated post generation, lead qualification, and scheduled social publishing to LinkedIn and X.
