How we built a non-blocking, RESTful API based on Vert.x and Kotlin/Coroutines
In this technical retrospective (2018), @lichtenberger shares practical architectural lessons learned from running, scaling, or migrating production software under lean constraints.
Core Principles for Independent Builders:
Defaulting to simpler architectures (such as monolithic frameworks, SQLite, or managed VPS) prevents early engineering bankruptcy.
Evaluating true compute and egress costs reveals that high cloud bills can often be slashed by 80%+ through judicious re-platforming.
Code you write at 2 AM as a solo engineer must be easy to debug six months later without complex microservice dependencies.
Community Debate Themes:
HN engineers debated the tradeoffs between cloud convenience and raw server economics, database indexing strategies, and resisting premature architectural complexity.

Wanted to share again, as I posted during the night, that is at least in Germany. Hope that's okay. I'd really love to get to know what you think, as it's Open Source and will stay so forever :-)
