AI Engineer

IT Klemen Zivkovic SP

Intelligent Crypto Trading Agent: Designed, prototyped, and deployed AI agent using ML/LLM stack. Built PyTorch DQN with custom NN (batch norm, dropout), trained via reinforcement learning on technical indicators (MACD, RSI, Stoch RSI, EMAs). Implemented experience replay, epsilon-greedy exploration, stop-loss/take-profit risk controls, and metrics tracking (win rate, max drawdown).
TradeCompetition Platform: Led full-cycle development of real-time AI trading competition system for crypto markets. Engineered modular OOP framework in Jupyter for rapid prototyping of indicators, prompts, and agent logic.
High-Throughput Pipeline: Processed 1-min candles for 6+ assets (BTC, ETH, SOL) via Binance/Bybit (ccxt, python-binance, pybit) with failover. Used Redis Streams + Pub/Sub for real-time caching/distribution, XML persistence with gap detection/backfill, handling 10k+ rows/asset.
Technical Analysis: Computed 20+ indicators (EMA, MACD, RSI, ATR) using NumPy/TA-Lib, optimized for high-frequency loads. Tracked PNL, Sharpe ratio, win rate, max drawdown with time-series rigor.
Multi-Agent Engine: Powered by DeepSeek API + local Ollama models; generated BUY/SELL/HOLD signals with confidence via structured prompts. Enabled concurrent strategy execution and benchmarking using optimization (LP/MILP) and predictive modeling.
Interactive Dashboard: Built with Flask + Flask-SocketIO, WebSocket updates (5s), REST APIs (/api/agents, /market, /leaderboard), and Plotly.js visualizations. Fully autonomous, scalable for research/production.
PriceFinderApp – Intelligent Product Configurator & Pricing Engine: Built and continuously improved a production-grade desktop GUI application (Python/Tkinter/Pandas/OpenPyXL) that loads country-specific 2025 price lists, supports real-time feature selection with automatic price calculation, leading-line logic, discount application, and multi-currency output. Integrated seamless XML import/export with the LangChain email agent, added geometry validation rules, automatic upsell recommendations via embedded LLM calls, and export to branded HTML/PDF offers with Plotly visualizations. Currently deploying web version (FastAPI + React) for sales team use.
Pool Cover Automation Suite – Email-to-Quote Automation with LangChain + RAG: Architected and deployed a fully autonomous LangChain-based agent pipeline that processes incoming customer inquiry emails (IMAP/Gmail), extracts structured pool dimensions, model preferences, features, colors, leading line requirements and country-specific pricing rules using LLM parsing + structured output chains, then applies Retrieval-Augmented Generation (RAG) over a continuously updated vector database. Achieved 98%+ accurate XML generation for the PriceFinderApp, auto-filled the Tkinter pricing tool, generated HTML/PDF offers with dynamic tables and 3D preview links, attached fully priced Excel breakdowns, and replied to customers in their native language within 3–5 minutes. Implemented fallback human-in-the-loop routing, confidence scoring, and self-improving few-shot prompt evolution, reducing manual quote preparation time from 20–40 minutes to under 4 minutes while eliminating data-entry errors.
