Viktor Berg: Data Analyst, IT Specialist, Logistics

LinkedIn: Viktor Berg Email: viktorsbergs@gmail.com

πŸ‘‹ Hi, I'm Viktor

I'm a data analyst and IT specialist at a third-party logistics (3PL) company. I build the reporting a warehouse runs on: Python pipelines that turn raw warehouse-system exports into KPI reports, FIFO checks and Power BI dashboards, so no one has to put them together by hand.

Outside work, I pick questions I'm curious about and answer them with data. Is AI a bubble? How unusual is Luka DončiΔ‡'s hot start? Can a dashboard build itself?

  • πŸ“¦ At work: warehouse KPIs, operator performance, inventory and capacity planning
  • πŸ“Š Strongest in: SQL and Excel, plus Python, Power BI and Power Automate
  • πŸŽ“ At university: information security, cryptography and C programming
  • πŸ“« Reach me: LinkedIn or viktorsbergs@gmail.com

πŸš€ Featured projects

Tracks all 10 players straight from a TV broadcast, maps them onto a top-down court in feet and measures offensive spacing frame by frame, with a broadcast-style overlay video and CSVs for SQL and Power BI.

Python YOLO OpenCV SQL Computer vision

Tools I built and run in a real 3PL warehouse: over a dozen pipelines that turn system exports into daily and monthly KPI reports, operator scoring, FIFO compliance checks and Power BI datasets.

Python pandas Plotly Power BI PowerShell

An early-warning system that re-scrapes market data every week, rebuilds a SQL feature warehouse and runs seven models to estimate the odds and timing of an AI-stock crash.

⛰️ Hillside AI

A web app that turns a spreadsheet into an interactive dashboard: it profiles the data, talks through what matters, and builds charts you can filter and edit.

FastAPI pandas JavaScript Plotly.js LLMs

πŸ€ NBA Analysis

Data stories published as LinkedIn carousels, each rebuildable from public data: Luka's record-setting start and what going 2-for-1 at the end of a quarter is worth.

Python SQL R Excel

IBM Data Science capstone: API and web-scraped data, SQL, interactive maps, a Dash app, and four tuned classifiers that predict whether a Falcon 9 booster lands.
