How we built Selfyx a lean generative images app
In this technical retrospective (2024), @ShayNehmad 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.

Special thanks to https://x.com/kohya_tech for his amazing open source software, that we couldn't have done without, and to https://x.com/modal_labs for their game changing serverless GPU calls, that enable a small startup like ours to produce cutting edge results in an affordable rate ♥
