Blockchain Development & Protocol Engineering
I work on the underlying systems behind blockchain products, from node architecture to the interfaces wallets and explorers use.
Protocol and product work
I build blockchain components where consensus, cryptography, networking and client interfaces must agree on the same rules. That includes node logic, verification, peer communication and APIs used by wallets or explorers.
- Full-node implementation and transaction processing
- Consensus and block validation
- P2P discovery and block propagation
- Merkle tree verification
- Wallet and explorer-facing JSON-RPC or gRPC APIs
- Post-quantum signature integration where justified
Qbitcoin as proof
For Qbitcoin I worked as Lead Blockchain Developer and Cryptography Engineer on a Python full node. The work covered a consensus engine, Merkle verification, Kademlia-based peer discovery, and JSON-RPC/gRPC interfaces for ecosystem clients.
I integrated Falcon-512 signatures into key generation, signing and verification flows to replace ECDSA in that project. The case study describes the scope and engineering choices without claiming a security audit or inventing performance results.
How I approach a new chain or integration
The first step is to define the trust model and compatibility requirements: the transaction format, signing rules, peer model, consensus assumptions and expected clients. From there we can identify which components need to be built, extended or independently reviewed.
