Recovering the Architecture of a Mature System
Representative engineering work
Understanding dependencies, constraints, and trust boundaries before defining a modernization path.

Context
A representative architecture-assessment scenario for a mature production system whose behavior, integrations, and operational constraints had evolved over time.
Challenge
The system contained valuable business behavior alongside multiple integration patterns, implicit dependencies, duplicated logic, and trust boundaries that were not documented in one place.
Engineering Approach
Recover the current state before prescribing the future state: trace dependencies, identify why key decisions exist, map operational constraints, and distinguish working behavior from change-blocking debt.
Architecture / Technical Decisions
Document application, API, identity, data, platform, and infrastructure boundaries together. Define modernization seams where change can be isolated, validated, and reversed instead of treating the system as a blank slate.
