Data Analyst & Engineer – I build automated data pipelines and business dashboards.
From Airbus to freelance projects, I turn raw data into smart, scalable systems that improve visibility, decision-making, and performance.
Specialized in dbt, Airflow, Streamlit, and Python – let’s automate what matters.

About

I’m a hybrid Data Analyst & Engineer with 3+ years of experience turning raw data into clear, automated systems for decision-making. My work blends data pipeline automation, dashboard design, and business-focused analytics to help teams move faster and act smarter.

At Airbus, I led end-to-end data initiatives across HR, design, and manufacturing — including:

  • Automating KPI pipelines using dbt + SQL
  • Building alerting systems with anomaly detection models
  • Deploying dashboards in Streamlit, Power BI, and Tableau

I specialize in making data tools that are clean, scalable, and actually used — not just theoretical models. I care about results: faster insights, clearer visibility, and fewer bottlenecks for product and ops teams.

  • Languages: Python, SQL, Bash
  • Automation & Data Engineering: dbt, Airflow, Git, Skywise, APIs, Docker
  • Visualization: Streamlit, Power BI, Tableau, Looker Studio
  • Machine Learning: scikit-learn, NLP (BERT, transformers), anomaly detection
  • Cloud & Platforms: GCP (BigQuery), AWS (basic), Redshift, Snowflake

I'm currently focused on remote and freelance missions — helping teams build automated reporting systems, ETL workflows, and real-time dashboards. Let’s simplify your data and turn it into action.

Because great data work isn't about complexity — it's about clarity, speed, and usability.

Experience

Data Analyst
    • Built an end-to-end KPI automation pipeline using dbt, SQL, and Skywise to feed interactive dashboards for HR and product teams.
    • Deployed real-time dashboards in Streamlit, Tableau, and Power BI — used by 5 cross-functional teams to track operations and priorities.
    • Developed alerting systems using anomaly detection models (Isolation Forest + rule-based logic) to flag high-risk engineering changes.
    • Extracted insights from technical documents with BERT-based NLP models, improving auditability and decision speed.
    • Collaborated with engineers, HR leaders, and PMs to define KPIs, improve data pipelines, and ensure delivery of actionable tools.
    • Tools: Python, SQL, dbt, Airflow, Streamlit, Tableau, Power BI, Skywise, scikit-learn, Transformers

Projects

Retail Analytics Pipeline
Retail KPI Pipeline

A full-stack data pipeline that surfaces key retail insights using Airflow, dbt, and Streamlit.

Accomplishments

    Tools: Airflow, dbt, Snowflake, Streamlit, SQL

    Problem: Retail managers manually track weekly sales KPIs across 50+ stores—time-consuming and error-prone.

    Solution: Built an Airflow DAG to ingest raw sales data (S3 → Snowflake), transform with dbt, and refresh a Streamlit dashboard every morning.

    Tech & Orchestration: Airflow (daily schedule + retry logic) → Snowflake warehouse → dbt models & tests → Streamlit UI

    Impact: Reduced manual KPI collection from 4 hours/week to 5 minutes; enabled real-time trend spotting and drill-downs.

E-Commerce Copilot Dashboard
E-Commerce Copilot Dashboard

A data dashboard for project managers, built with real-world e-commerce data.

Accomplishments

    Tools: Python, Pandas, Plotly, Streamlit, Streamlit Cloud, Kaggle

    Problem: Online retailers juggle dozens of metrics—conversion, cart abandonment, revenue per channel—using disconnected spreadsheets.

    Solution: Built an Airflow DAG to ingest raw sales & customer data into Redshift, transform with dbt, then publish an interactive Streamlit dashboard that unifies metrics in one place.

    Tech & Orchestration: Airflow (daily schedules + failure alerts) → Amazon Redshift → dbt models & tests → Streamlit UI

    Impact: Cut manual reporting from 5 hours/week to under 10 minutes; empowered marketing & product teams with on-demand insights.

churn app
churn app

A full-stack ML app that predicts telecom customer churn with live inputs and risk insights.

Accomplishments

    Tools: Python, Streamlit, scikit-learn, XGBoost, SHAP, SMOTE

    Problem: Telecom operators struggle to spot at-risk customers before they leave, leading to reactive retention efforts.

    Solution: Orchestrated a pipeline that cleans Telco data (Kaggle), trains a churn model daily (XGBoost + SHAP), writes scores to Snowflake, and updates a Streamlit alert dashboard.

    Tech & Orchestration: Airflow (monthly retrain + daily scoring) → Snowflake warehouse → Python ML (XGBoost, SHAP) → Streamlit dashboard with email/slack alerts

    Impact: Identified top 5% high-risk accounts each morning, enabling targeted retention and reducing churn by an estimated 15% in simulation.

Multilingual Sentiment Classifier (BERT)

A multilingual NLP app that classifies customer reviews as positive or negative using BERT.

Accomplishments

    Tools: HuggingFace Transformers, BERT, Deep Translator, Streamlit

    Problem: Global brands need real-time sentiment across multiple languages but often rely on manual translation and siloed tools.

    Solution: Built an Airflow DAG to ingest tweets, translate text with Hugging Face pipelines, run sentiment classification, and store results in BigQuery. A Streamlit dashboard visualizes sentiment trends by language and region.

    Tech & Orchestration: Airflow (hourly fetch + translate jobs) → Google BigQuery → Python (Hugging Face, fastAPI) → Streamlit UI

    Impact: Automated sentiment reports across 5 languages, cut manual translation/analysis time by 90%, and provided marketing teams with instant brand health insights.
