Junior Data Analyst · AI-Assisted Development · Switzerland
Turning data and ideas into smart digital solutions.
I am Asser Zaytoun, originally from Egypt and based in Morges, Switzerland. I turn raw data into clear, decision-ready insights, with training from the EPFL Extension School and practical experience in R, SQL, statistics, APIs, data cleaning, visualization, and reporting.
I also design, build, and rebrand modern multilingual websites using AI-assisted development — from new builds to full visual rebrands for existing businesses — with several projects already delivered. My ten years of experience in service and operations help me create digital solutions that are practical, business-focused, and aligned with real user needs.
Profile
From entertainment to data, coding, and digital solutions.
I clean, explore, visualise, and report on real data — and explain what it means in plain language. Alongside analysis, I build practical digital tools with careful UI and UX. My years in entertainment, service, and operations give me something data skills alone cannot: I read people well, stay calm under pressure, and never lose sight of the business question behind the numbers.
Education
EPFL Extension School — applied data science. Hands-on projects in R, SQL, web scraping, APIs, statistics, and data visualisation.
Background
With ten years of experience in entertainment, alongside a strong background in hospitality and operations, I have developed the ability to understand people, remain dependable under pressure, and deliver consistent results every day.
Selected work

SQL
API

Projects.
Two sides, one goal: I turn raw data into answers people can act on — import, clean, analyse, visualise — and I build clean, responsive interfaces that make those answers easy to use.
Rental Market Analysis
Scraped and cleaned Swiss rental listings to answer a concrete question: how do location, visibility, and size drive the price per square metre?
Zurich Politicians Database
Queried a relational SQLite database of Zurich politicians to reveal gender balance, party shares, and how political careers have evolved over time.
Movie Data API Project
Collected movie data from a live paginated API, then compared studios, ratings, and voting patterns through clear visual summaries.
Reporting Portfolio
KPI dashboards, charts, and tables built with one rule: a decision-maker should understand the situation in under a minute.
Di Biase Services Group
Designed and delivered a full rebrand and multilingual website for a real business client — new visual identity, service packages, contact flow, and a fully responsive layout.
Visit site → WEBAdvanced Property Management
Designed and built a professional property management website for an international real estate company covering five Red Sea resort destinations — service packages, owner-facing presentation, and a fully responsive layout.
Visit site → WEBO Mundo das Crianças

Skills
Practical tools with a clear workflow.
The tools I use to answer real questions: R, tidyverse, ggplot2, SQL, Excel, Power BI and Tableau basics, API workflows, statistics, front-end web design, and AI-assisted development.
1
Data Science
I work through the full data cycle — import, clean, explore, model, communicate — turning messy real-world data into findings people can trust.
2
Artificial Intelligence
I use AI as a working tool: integrating language models into projects and workflows to automate steps, draft content, and speed up analysis — while keeping quality under my control.
3
Machine Learning
I know the core ideas — training, validation, overfitting — and apply simple models honestly: clear about what the data can support and what it cannot.
4
Data Visualization
I design charts that answer a question at a glance — the right visual form in ggplot2 or a BI tool, with everything that distracts from the message cut away.
5
Data Management
I structure, store, and document data so it stays accurate and usable — from clean spreadsheets to relational SQL databases.
6
Critical Reading
I test claims against their evidence — reading reports and data critically to catch weak arguments, hidden assumptions, and missing context before they become bad decisions.
7
GitHub
I version my projects with Git and GitHub — tracked changes, clean history, and published repositories ready to share.
8
Jupyter Notebook
I work in notebooks to combine code, results, and explanation in one reproducible document — the way modern data teams share their analysis.
9
Front-end Web Design
I build responsive, modern websites from scratch in HTML, CSS, and JavaScript — layout, animation, glass UI, and mobile-first design, no heavy frameworks needed.
10
Back-end Development
When a project needs a server side, I build it: REST APIs in Node.js or Python, SQL and SQLite databases, and clean connections between interface and live data.
11
AI-Assisted Development
I ship complete products fast by pairing solid fundamentals with AI tools — precise prompting, iterative design, and a tight feedback loop from idea to working product.
