Baldetskiy

Backend and blockchain developer focused on small, testable deliverables in Python, C#/.NET, SQL/SQLite and Solidity. I can help with REST API integrations, CSV/Excel import and validation, order and payment reconciliation, Telegram bots, and ERC-20 or staking prototypes and tests. We can agree on a bounded first milestone with clear acceptance checks before expanding the scope. You receive source code, tests and setup notes. My LaborX portfolio has six clearly scoped demos. Runnable code and screenshots: https://github.com/pepelaz1. These are local demonstrations; production deployment and security review are separate.
