Your Solo Developer Deserves Backup

When an entire application depends on a single developer, institutional knowledge becomes a hidden liability — what the author calls 'knowledge debt.' Rather than pursuing a rewrite, the recommended approach is bringing in a second team whose primary goal is to learn from the solo developer, document undocumented decisions, and gradually share the cognitive load. This preserves years of hard-won system knowledge, reduces the bus-factor risk, and gives the primary developer the freedom to take time off or focus on new work without the system being at risk.
