Murat Sarikoca
Engineer-founder who has been writing code for 20 years, the last decade professionally, shipping production systems across fintech, crypto, and SaaS, from early architecture through execution, iteration, and revenue. I stay close to the code while owning technical direction: clean abstractions, pragmatic decisions, and software built to last. Deepest in Type Script, Rust, Go, and Python, with strong experience in payments, EVM/L2 infrastructure, account abstraction, and AI products.
Motivated by 0→1 and 1→100.
