Situation: I had spent three days drafting a comprehensive technical proposal to build a custom in-house WebSocket gateway for our real-time notification system, feeling confident in my design.
Task: During the architecture review, a teammate proposed leveraging AWS AppSync and managed GraphQL subscriptions instead, which would fulfill all our requirements with zero server maintenance.
Action: Although I was personally invested in my custom gateway design, I checked my ego and evaluated their proposal objectively. I analyzed the operational trade-offs: my custom solution would require ongoing on-call support, custom horizontal scaling algorithms, and dedicated server maintenance, whereas managed subscriptions met our 10,000-connection requirements out of the box with built-in authentication. I openly conceded that their approach was far more pragmatic for our small team, archived my proposal, and collaborated with them to integrate the managed solution.
Result: We delivered the notification system in three weeks instead of the projected eight weeks, freeing up engineering capacity to ship two additional roadmap features. My teammate felt respected, and the team avoided taking on unnecessary infrastructure maintenance.
