The Captain's Log — Backend Diaries

The Captain's Log—Backend Diaries is owned by Oni Christopher Ifeoluwa, and it is where I document the real work behind building distributed, event-driven backend systems.

Four formats, one series:

• Architecture Reviews—deep dives into systems I've designed, the trade-offs, and what I'd change.
• Debug Logs—real production incidents, the hunt, the root cause, the fix
• Build Logs—live notes from features as I build them, not polished after-the-fact
• Discoveries—quick TIL-style posts on tools, patterns, and techniques worth sharing

No tutorials for their own sake—just the actual decisions and lessons from building fintech and SaaS infrastructure at scale.
