About me
Software engineer focused on Rust, Go, and Solana development, with full-stack capability when projects need a complete delivery. On the Web3 side, I write smart contracts in Rust using the Anchor framework, work with SPL tokens, and build the TypeScript clients that interact with on-chain programs. Outside Web3, I build performant backend services in Rust (Axum, Tokio) and Go, typically backed by Postgres. When a project needs a frontend or mobile layer, I use Flutter for cross-platform apps, Python (FastAPI) for additional backends, and Python automation for scraping and LLM workflows.

Recent projects include Solana programs built with Anchor (smart contracts, SPL token flows, on-chain/off-chain coordination), Go microservices exposing REST and gRPC APIs, and Rust backend services using Axum and Tokio. Also handle full-stack work when needed — Flutter mobile apps, Python (FastAPI / Django) and Node.js backends, and automation pipelines that integrate third-party APIs and LLMs. Day-to-day involves scoping with clients, writing production code, code review, and shipping against deadlines.
