Software engineer / Data infrastructure
Make data dependable.
I'm Wilter Yee, a software engineer on Persona's Data Platform team. I work in the space between data movement, storage, and access—where reliability, practical architecture, and useful abstractions matter. Previously at Twitch, Gem, Slack, Apple, and Qualcomm.
// Systems thinking, from ingestion to impact.
system principles
01 / Focus areas
Infrastructure that
gets out of the way.
My interests sit where distributed systems, developer experience, and reliable data meet.
Data infrastructure
Ingestion, data movement, processing, and the contracts that turn pipelines into dependable systems.
Platform engineering
Self-service workflows, APIs, tooling, and paved roads that make the right path the easy path.
Reliability at scale
Observability, recovery, graceful failure, and the engineering discipline behind steady operations.
02 / An interactive sketch
Every boundary is a design decision.
Reliable data systems are more than a series of boxes. Select a stage to explore the principles I think about across the lifecycle.
Read the longer noteTreat inputs as contracts
Systems are easier to operate when producers, schema expectations, and ownership are explicit.
Illustrative architecture, not a production system or client diagram.
03 / Engineering notes
Things worth
thinking through.
Notes on the decisions, tradeoffs, and practical realities behind good engineering systems.
The boring parts of a reliable data platform
Contracts, failure modes, ownership, and the work users never see.
Backfills are a first-class workload
Designing for replay and recovery before they're emergencies.
Build paved roads, not cages
On productive platform abstractions and responsible escape hatches.
04 / Say hello
Good systems start
with good questions.
