Wei-Ting Liu
NTU Information Management + Trans-disciplinary Bachelor Degree.
Undergraduate at National Taiwan University, working across business, data, and engineering.
Open to every chance and place to learn.
Third-year B.B.A. student in Information Management at National Taiwan University (GPA 3.96 / 4.30), double-majoring in the Trans-disciplinary Bachelor Degree at the College of Innovation and taking SCAP, BCG and NTU's strategy-consulting course. Interested in problems that sit between business, data, and engineering.
Four internships at ABConvert and NTU iNSIGHT so far: a pricing-experiment framework and simulator, internal dashboards that cut ~70% of manual metric lookups, AI adoption workshops that moved 80% of staff from chat-based AI use to building their own tools, and most recently a dual-loop RL system for optimizing Shopify stores.
Outside of work: two computational-epidemiology research projects with citable replication archives, Vice President of the NTU Information Management Student Association, and Spotify GuessSong, a side project with 70,000+ monthly active users.
National Taiwan University
B.B.A. in Information Management · Double Major: Trans-disciplinary Bachelor Degree (College of Innovation)

ABConvert — Reinforcement Learning R&D Intern
Shopify A/B Testing SaaS
- Designed a dual-loop RL system that trains agents to optimize Shopify stores, aiming to build an accurate, real-world-calibrated simulator that closes the sim-to-real gap.
NTU iNSIGHT — AI Intern
Service-design consultancy
- Developed an internal service-design product and led AI adoption workshops, moving 80% of staff from chat-based AI use to building their own website products.
ABConvert — Software Engineer Intern
Shopify A/B Testing SaaS
- Migrated abconvert.io (10 pages) from Webflow to a self-hosted Next.js app, reaching a 97 Lighthouse SEO score and enabling custom interactive components.
- Built internal dashboard features (experiment research, visualization, analysis) from a cross-team needs survey, eliminating ~70% of manual metric lookups for Customer Success and the CEO.
ABConvert — Startup Generalist Summer Intern (Product/AI)
Shopify A/B Testing SaaS
- Designed a pricing-experiment framework turning revenue, margin, and share goals into testable hypotheses, plus a simulator for price elasticity, customer lifetime value, and segment-level optimal prices.
- Wrote the product spec for the experiment workflow: sample-size calculation, guardrail metrics, rollout strategy, and decision rules balancing statistical rigor with speed.
Multi-Agent RL for Decentralized Epidemic Surveillance
Advised by Wayne Lee · 10.5281/zenodo.21619163
- Built a CTDE multi-agent RL framework (MAPPO/QMIX/IPPO/CQL) casting Brazil's 26 states as agents alerting on dengue from 258 weeks of cases and Google Trends, benchmarked against an information-parity rule.
- Traced the agents' shortfall to task specification (reward misalignment, sample inefficiency), not RL: the same agents learn control on SIR/SIS simulators. Manuscript in preparation; 107-checkpoint archive released.
Age-Mixing Structure in Aggregated Urban Mobility Data
Advised by Wayne Lee · 10.5281/zenodo.22152089
- Measured age mixing across 10.2 billion rows of Seoul mobility data (79 months, 424 districts, 16 age bands): co-arrivals sit within 0.00202 of proportionate mixing every month, 33–35× below a national contact survey.
- Verified the near-zero reading with a synthetic-world calibration that fixes the detection limit: the pipeline recovers 92–101% of true assortativity, confirmed by an independent re-implementation (436/436 checks).
Built and operate a real-time multiplayer music-quiz web app (any Spotify playlist becomes a live quiz) that reached 70,000+ monthly active users.
olcli — Overleaf CLI
Open-source contributor
7 merged contributions to a 200+-star open-source Overleaf tool with 2,500+ monthly npm downloads: a diff feature (900+ lines) that lets users review changes before syncing, CI gating, a security fix, and contributor docs.
Open to internship opportunities in consulting, product, SWE, and AI/ML.
