Alla Stancheva

Junior Data Analyst

Amsterdam

An engineering background paired with modern data and AI tooling. I turn messy, scattered data into decisions teams can act on.

Projects

A real business result, not a course exercise — the problem, what I did, and the measurable outcome.

Reducing defect rate in manufacturing

Problem

A high defect rate (40%) on the production line was driving up costs and waste.

What I did

Ran an analytical root-cause investigation of the process and the data behind it, then validated the fix against the numbers.

Defect rate cut from 40% to 2%.

Skills & Tools

From the classics to a modern AI stack. AI is the part I genuinely enjoy — and what sets me apart from a typical junior.

Data

  • SQL
  • Python
  • BigQuery
  • Excel / Sheets

BI

  • Power BI
  • Tableau
  • Metabase
  • Looker Studio

Automation

  • n8n
  • Docker
  • Google Tag Manager

AI

What sets me apart as a junior — building with modern AI tools, not just reading about them.

  • Claude Code
  • RAG
  • PostgreSQL + pgvector
  • AI-assisted development

About me

My first profession is engineering: I graduated from Odesa National Polytechnic University, in computer engineering. That is the lens I bring to any dataset — I see it as a system with a structure and an internal logic.

Moving into analytics was a deliberate choice, and I keep learning on my own. I'm especially drawn to modern AI tools — Claude Code, RAG systems, agents. I don't just analyse data: I value time, which is exactly why I keep growing my automation skills.

Beyond data, I'm curious about psychology, TRIZ (the theory of inventive problem solving), prompt engineering and AI-assisted development. These aren't random hobbies — they're how I keep my thinking flexible and look at a problem from several angles.

Values

I do my best work on things that matter to me: human health, education, personal development and philosophy. In these areas I want to dig deeper — the data is usually there for real decisions, not just for a report.
