AI Engineer

IT Klemen Zivkovic SP

Designed, prototyped, and deployed AI agent using ML/LLM stack with PyTorch DQN, custom neural network (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)
Led full-cycle development of a real-time AI trading competition system for crypto markets, engineering a modular OOP framework in Jupyter for rapid prototyping of indicators, prompts, and agent logic
Processed 1-minute candles for 6+ assets (BTC, ETH, SOL) via Binance/Bybit (ccxt, python-binance, pybit) with failover; used Redis Streams and Pub/Sub for real-time caching/distribution, XML persistence with gap detection/backfill, handling 10k+ rows/asset
Computed 20+ technical indicators (EMA, MACD, RSI, ATR) using NumPy/TA-Lib, optimized for high-frequency loads; tracked PNL, Sharpe ratio, win rate, and max drawdown with time-series rigor
Powered a multi-agent engine using DeepSeek API and local Ollama models to generate BUY/SELL/HOLD signals with confidence via structured prompts; enabled concurrent strategy execution and benchmarking using optimization (LP/MILP) and predictive modeling
Built an interactive dashboard with Flask, Flask-SocketIO, WebSocket updates (5s), REST APIs (/api/agents, /market, /leaderboard), and Plotly.js visualizations, fully autonomous and scalable for research/production
Developed and continuously improved PriceFinderApp, a desktop GUI application (Python/Tkinter/Pandas/OpenPyXL) for country-specific 2025 price lists, real-time feature selection, automatic price calculation, discount application, multi-currency output, XML import/export via LangChain email agent, geometry validation rules, automatic upsell recommendations via embedded LLM calls, and export to branded HTML/PDF offers with Plotly visualizations; currently deploying a web version (FastAPI + React)
Architected and deployed Pool Cover Automation Suite using LangChain and Retrieval-Augmented Generation (RAG) to process customer inquiry emails, extract structured data, apply pricing rules via RAG over a vector database (Chroma + OpenAI embeddings), auto-generate XML for PriceFinderApp, auto-fill Tkinter tool, generate HTML/PDF offers and Excel breakdowns, and reply to customers within minutes; implemented human-in-the-loop routing, confidence scoring, and self-improving prompt evolution, reducing manual quote preparation time from 20–40 minutes to under 4 minutes while eliminating data-entry errors.
