Developer Infrastructure Platform

Problem

Build a developer-facing infrastructure platform with APIs, SDKs, and platform services from the ground up.

Context

Early-stage company, compliance-heavy environment, multi-stakeholder coordination across engineering, design, legal, and operations.

Constraints

Interface stability prioritized over feature velocity. Regulatory requirements shaped technical architecture. No existing developer tooling to build on.

Approach

Decomposed user requirements into technical specifications. Introduced a dependency-mapping practice across squads. Structured release cycles to surface cross-team blockers before they reached production.

Metrics

3 cross-team blockers surfaced before production

API contracts defined before implementation

Structured release cycle established

Lessons

01

Prioritize interface contracts over feature shipping

02

Developer experience is a product, not a feature

03

Dependency mapping pays for itself in the first sprint
