Recent work
GTM data engineering and attribution
Identity stitching, lifecycle reporting, and warehouse modeling that make revenue reporting easier to trust.
Edwin Tse
I build data systems teams can trust.
I work across data engineering, analytics engineering, product measurement, and operational reporting. Most projects start with fragmented systems, disputed metric definitions, and decisions that depend on getting the logic right.
I turn that into warehouse models, reporting layers, and measurement workflows teams can inspect, explain, and use with confidence.
Operations and BI
KPI systems that people actually use
Metric governance, dashboard workflows, and reporting cycles built for faster decisions.
Longer thread
Transportation, planning, and fairness
A systems lens shaped by public infrastructure, incentives, and real-world trade-offs.
Selected work
Selected projects across data systems, measurement, and transportation analysis.
A concise cross-section of the systems, tools, and analyses I have built in professional and independent work.

Customer 360 and Revenue Attribution Warehouse
Unified CRM, product, billing, and support data into an account-level model that made GTM revenue reporting easier to trust and use.
A strong example of identity stitching, attribution logic, and cross-functional metric governance in a messy operating environment.

Modern ELT Reliability Platform
Built an ELT foundation with testing, monitoring, lineage, and reusable patterns so analytics data held up under wider use.
Shows production-minded data engineering rather than one-off pipeline work.

Funnel Deep-Dive and Experimentation Measurement System
Standardized event instrumentation and experiment readouts so product changes could be tied back to activation and onboarding outcomes.
Shows product analytics rigor, not just dashboarding.

FlightPriceBias
Investigated airfare pricing and fairness risk through predictive modeling and algorithmic bias analysis.
Combines predictive modeling with transportation economics and real fairness trade-offs.

Transit Hub Access Study
Evaluated access, safety, and connectivity around transit hubs through GIS and urban planning analysis.
Connects spatial analysis to access, safety, and planning decisions in public systems.
What I bring
I do my best work where messy processes still need clear numbers.
I do my best work where implementation quality and judgment both matter. That usually means defining logic clearly, building reliable data flows, and making sure the output still holds up once other teams depend on it.
I care about definitions, edge cases, and the operating reality behind reported numbers, whether the context is revenue reporting, product measurement, logistics workflows, or transportation analysis.
Contact
I’m interested in data engineering, analytics engineering, and product analytics roles.
