Data Engineer
I'm Alex Kargin, a data and ML/AI engineer based in Boca Raton, Florida. I build production data pipelines and applied AI systems — the kind that actually get used, not the kind that win a hackathon and die in a prototype folder.
I founded kargin-utkin.com, a data engineering publication with hands-on writeups on PostgreSQL, ClickHouse, dbt, Airflow, PySpark and Kafka — plus a 14-course Learn platform covering SQL fundamentals through distributed systems internals. I also founded InnovaTek Solutions, a consultancy specializing in private AI installations and legacy-system modernization for regulated industries.
Currently focused on Snowflake data warehousing, Dagster orchestration, building end-to-end ELT pipelines, and self-hosted LLM deployments for air-gapped environments.
Production systems handling real-time data, ML pipelines, and cloud infrastructure.
Database migration platform that analyzes legacy MySQL/PostgreSQL/MSSQL schemas and generates cloud-ready DDL for PostgreSQL and Snowflake. Includes a real-time financial data pipeline (Alpha Vantage → PostgreSQL → ClickHouse) with interactive dashboards.
Real-time news monitoring system that ingests 100+ articles daily from 30+ RSS feeds, applies spaCy NER to identify mentions across a 132K celebrity database, and scores content on a 1–10 severity scale with fuzzy name matching.
Quote discovery platform with 3M+ quotes and 100K+ authors. Features ML classification pipelines, local LLM inference (Ollama), sentiment analysis, and multi-server architecture with dedicated GPU processing for ETL workloads.
Prediction market analytics with dual-server architecture. A local GPU analytics engine orchestrated by Dagster pushes processed data to production via SSH tunneling for real-time market insights with LLM-powered analysis.
Crypto trading desk simulator with real-time market data ingestion from CoinGecko API, automated AI-driven daily market analysis, decision tracking, and scheduled data pulls with historical analytics.
Data & ML engineering hub with technical guides on ETL pipelines, vector databases, GPU analytics, and lakehouse architecture. Features curated AI/data industry news, tool comparisons, and an ecosystem directory of 23+ categories across the modern data stack.
AI-powered personal styling platform that analyzes body type, skin tone, and proportions from uploaded photos to generate tailored outfit recommendations. Features a chat stylist interface, body shape classification, and shoppable outfit suggestions.
