Career Timeline
Qtum is an open-source proof-of-stake blockchain that combines Bitcoin's battle-tested UTXO model with the Ethereum Virtual Machine through its Account Abstraction Layer — bringing EVM smart contracts to a UTXO base. As a Blockchain Engineer, I develop distributed ledger systems for large, complex production-level environments — from wallet tooling and node infrastructure to core-protocol testing — while ensuring secure deployment.
Main-maintainer of the Qtum-Snap project, working in depth with MetaMask — building custom wallet architecture that enables seamless interaction with the Qtum blockchain directly inside the MetaMask environment.
Core contributor responsible for writing, executing, and maintaining robust Python test codes to ensure the stability and security of the primary Qtum Core Wallet.
A Python library implementing the BIP38 standard for the Qtum protocol, ensuring robust private key and WIF (Wallet Import Format) encryption and decryption.
Creator and main-maintainer of a decentralized platform providing reliable, secure, and scalable access to Qtum. Enables developers to build applications without managing node or server complexities.
Built an advanced Prometheus exporter for Qtum nodes. This monitoring tool extracts granular on-chain data and node health metrics, making it essential for node operators and enterprise deployments.
A diagnostic tool that scans Qtum Core debug files to detect and extract orphan blocks, helping node operators analyze chain reorganizations and block propagation health.
