Software Engineer building products and exploring blockchain systems.
I enjoy building things from the ground up, understanding how systems work underneath, and turning ideas into software people can actually use.
Currently focused on backend & systems engineering, exploring Solana and blockchains in general and building my own products.
A product I'm building for fiction writers.
Status: In active development
The codebase is currently private, but you can check our progress live:
Solana & Blockchain Systems
Experimenting with Solana, Rust, and several other Blockchains that pique my interest.
→ Check out my public blockchain projects below.
I'm currently going deeper into:
- Backend engineering
- Systems design
- Data structures and algorithm
- Distributed systems
- Software architecture
- Performance and scalability
I use real projects as a laboratory for applying what I learn.
