About Me
Iβm a software engineer with 8+ years of experience, with the last 5 years specializing in Rust systems programming, backend and blockchain infrastructure.
I live and breathe Rust β building high-performance distributed systems that leverage zero-cost abstractions without sacrificing low-level control.
What Iβve Built
- High-performance backends: Solid and secure backend infrastructure serving tens of thousands concurrent users
- Linux Kernel Enhancements: Rust-based per-peer workqueue system achieving 13.4% performance gains for millions of users
- eBPF XDP Firewall: Pure Rust firewall with NIC-level packet filtering
- Solana DeFi Protocols: DEX and governance systems using Anchor framework
- Substrate Runtime: Cross-chain runtime supporting 4 EVM chains
Technical Expertise
Core Skills:
- Rust/C interop and FFI
