Senior Dev Wisdom: Avoiding Needless Complexity
Description
A three-panel meme using screencaps from the anime 'Frieren: Beyond Journey's End'. In the first panel, a young magician with purple hair says, 'It is like programming with my grandfather.' In the second panel, she looks towards a figure flying away in the distance and continues, 'Ordinary functions and objects. You only use basic HTTP requests. Why are you avoiding complexity?' The final panel is a close-up of her face as she reflects, 'My mentor said it was enough for projects of this era.' The meme humorously captures the generational and experiential gap in programming philosophy. It contrasts a junior developer's fascination with complex, modern architectures and tools with a senior developer's pragmatic preference for simple, proven solutions that are sufficient to solve the problem at hand, a core tenet of the 'Keep It Simple, Stupid' (KISS) principle

The hardest part of modern software engineering is explaining to a junior dev that their five-microservice, event-driven, serverless solution for a blog could have just been a single script
Every time someone replaces a straightforward handler with a gRPC-Kafka-CQRS pipeline, a senior engineer quietly rewrites it as a single function and goes back to sleep
After 20 years in the industry, you realize the junior's 'grandfather programming' with simple REST endpoints will outlive your beautifully orchestrated GraphQL federation with event sourcing - and require 90% less maintenance budget when the next CTO arrives with their own architectural vision
When your senior architect suggests 'just use REST and PostgreSQL' for your microservices mesh proposal, and you realize they've been shipping production systems longer than your favorite framework has existed - sometimes the broom that sweeps is more reliable than the autonomous cleaning robot that needs three services, two message queues, and a distributed tracing system just to know which room it's in
Uptime improved and the cloud bill halved when we replaced CQRS + event‑sourced GraphQL microservices behind a service mesh with a single REST handler and plain objects - my favorite optimization is deleting architecture
Every time I replace a network hop with a function call, p99 drops and someone opens a ticket to ‘modernize’ it back into twelve services and a sidecar
Grandpa's cURL: zero schema drift, infinite uptime. Your GraphQL? Weekly versioning purgatory

Only bad developers admire complexity. Good devs appreciate simplicity. Comment deleted
PSA: please don't use this adage to protect simple-yet-not-generally-correct code Comment deleted
That has nothing to do with defending incorrect code tho Also, complexity has it's place, but most things do not need it Comment deleted
I've seen many, many people provide a simple solution to a complex problem and try to assure me it'll work just fine, citing that maxim Comment deleted
e.g. We don't need a database, a JSON file will work just fine or We don't need a specially designed sandbox, a Docker container will work just fine Comment deleted
I see. I undestand where this is coming from, but these look like POs/Architects not doing their jobs at explaining requirements Yet, I agree that simplicity should not be an excuse Comment deleted
We don't need a relational database, a NoSQL will work just fine. 🤡 Comment deleted
