 DARYNA DEVELOPER

Python Developer | Automation & Trading Solutions Specialist

Hello! I am a Python Developer focused on building high-performance software solutions that automate routine processes, extract data, and manage financial assets. My goal is to deliver stable, transparent tools that provide measurable results for your business.

 Core Competencies:

  • Trading Algorithms: Development of crypto exchange bots (MEXC, Bybit, Binance) using the CCXT library. Implementation of complex strategies based on technical indicators (RSI, Bollinger Bands, EMA, MACD).

  • Risk Management: Integration of margin control systems, automated Take Profit / Stop Loss, Hedge models, and protection against over-exposure.

  • Telegram Bots: Building multi-functional bots ranging from real-time monitoring systems to intelligent assistants with database integration.

  • API Integration: Connecting diverse services into a unified ecosystem for seamless automated data exchange.

 Why Clients Choose to Work With Me:

  • Code Reliability: I utilize modern development practices to ensure your bots run 24/7 without crashes or errors.

  • Live Monitoring: I always set up intuitive status dashboards (PnL, active positions, limits) so you have full control over the process.

  • Security: I handle API keys with strict adherence to security standards, including restricted access permissions and encryption.

  • Transparency: I provide clear documentation and operation manuals for every piece of software I develop.

I don’t just write code — I build tools that save your time and minimize human error.

    DEX Arbitrage & Cross-chain Bridge

    Bot Development
    Developed a sophisticated, high-performance automated trading bot designed to identify and execute risk-minimizing arbitrage opportunities across decentralized exchanges (DEXs) on leading Ethereum Layer 2 networks. The bot performs real-time market scanning, on-chain data analysis, and executes profitable trades while dynamically accounting for network gas fees and slippage.

    Key Features:
    Real-Time Multi-Chain Monitoring: Simultaneous price and liquidity tracking across Base, Arbitrum, and Optimism networks.

    DEX Aggregator Integration: Leverages the Odos API to source the most efficient swap paths, ensuring optimal execution prices and minimal protocol fees.

    11+ Asset Support: Monitors liquidity for major pairs including ETH, USDC, USDT, WBTC, cbBTC (Coinbase Wrapped BTC), LINK, UNI, and others.

    Cross-Chain Bridge Module (Across Protocol): Features an automated capital consolidation module that bridges profits from source chains back to a central operational chain (Optimism) using cheap and fast bridges.

    Smart Profit Calculation: Advanced algorithm that automatically deducts dynamic gas fees from potential spread profits. Trades are only executed when a predefined net profit threshold is met.

    Telegram Notification System: Full integration with the Telegram API for real-time alerts on portfolio status, market conditions, and detailed trade execution reports.

    Technical Stack:
    Language: Python 3.10+

    Core Libraries: Web3.py (blockchain interaction), Requests (API connectivity), Telebot (interface), Threading (concurrency).

    Networks: Ethereum Layer 2 (Base, Arbitrum, Optimism).

    Infrastructure: Private RPC nodes, REST APIs (Binance, Odos, Across Protocol).

    Deliverables:
    A stable, production-ready trading tool operating 24/7 in the background. It effectively filters out unprofitable trades, manages gas costs dynamically, and provides the user with complete portfolio transparency through a convenient Telegram interface.
