Designing a single computation path for a cross-service metric
Two services independently calculated the same customer-facing metric, causing inconsistent data. I redesigned the architecture so only one service owned the calculation while every other service simply signaled stale data.
Founding an analytics service by moving reporting off the transactional database
Founded a new reporting service that separates heavy analytical reads from the transactional database, resolving indicator timeouts — framing the OLTP-vs-OLAP trade-off, critically reviewing the architecture decision, and building the walking skeleton and its data layer.
Building a hierarchical selector instead of taking a dependency
Needed a tree selector the UI library didn't provide. Chose to build a reusable abstraction instead of introducing another dependency.
Designing a safe human-in-the-loop AI agent for bulk route creation
Prototyped an AI agent that lets support create inspection routes in bulk from spreadsheets, designed around a safety rule — the LLM only ranks candidates and never emits identifiers, and all writes go through human-in-the-loop confirmation with preview/dry-run.
