Experience

Fullstack Developer, Crypto Coin Detection & Analysis System

January 2025 - May 2025

Description: Developed a .NET-based application that integrated with Etherscan, TokenSniffer, Alchemy, and Basescan APIs to automatically detect all newly created tokens on the Ethereum network. In alignment with the client’s vision, the system applied custom heuristics and real-time on-chain data to identify and filter out scam tokens, storing only legitimate tokens in a structured database.

• The system continuously monitored trading activity, tracked purchase patterns, and calculated the average holding period across multiple timeframes to assess investor sentiment and token volatility.
• A custom-trained LLM (Large Language Model) was also integrated to analyze market trends, historical price patterns, and social signals, offering predictive insights into a token’s potential for growth or decline.
• The solution leveraged functional programming principles through F#, enabling concise, immutable, and type-safe logic for core data transformations, token validation heuristics, and parallel computation of blockchain data streams.

Used Technologies: F#, Functional Programming, .NET Core, Nethereum, Nethermind, React, Telegram API, Etherscan API, TokenSniffer API, Basescan API, Alchemy API, Dextools, Dexscreener, Coinbase API
