Make architecture and system design decisions across backend services, databases (SQL and vector), APIs, and cloud infrastructure.
Dive deep into the business domain (marketing, SEO, GEO, content automation) to make smart product and engineering trade-offs.
Connect every engineering decision to user outcomes—ask “does this move revenue or retention?” before “is this technically elegant?”
Collaborate directly with founders and cross-functional teams, operating as a product-minded engineer rather than a spec-follower.
