## ๐ก Dev Philosophy
> *"Architecture is not just about making things work โ it's about making them last, scale, and remain understandable to the next engineer."*
- ๐ง I think in **systems**, not just code
- ๐ I value **feedback loops** โ fast tests, fast deploys, fast iteration
- ๐ I write code for **humans first**, machines second
- ๐ค I believe the best engineers **lift those around them**

If you're building something ambitious โ a high-scale API, an LLM-powered product, or a distributed backend โ I'd love to talk.
