Data Scientist with a strong Mathematics & Statistics foundation and 10+ years in education. I turn complex, unstructured data into decisions — NLP & LLM systems, RAG pipelines, large-scale web scraping & automation, and dashboards teams actually use. Let's analyze the data together 🚀

Python (Pandas · NumPy · SciPy) · SQL · R · JavaScript · Bash · HTML5 · CSS · Regex	scikit-learn · TensorFlow · Keras · PyTorch · MLflow · Pandas · NumPy · SciPy — classification, regression, clustering, model evaluation & tuning
LangChain · Hugging Face · Anthropic · OpenAI · spaCy / NER · LLMs · RAG · agents, prompt engineering & evaluation frameworks	Scrapy · Selenium · BeautifulSoup · Supabase · PostgreSQL · MongoDB · MS SQL Server · Elasticsearch · Typesense · Apache Kafka — automated pipelines & REST APIs
Tableau · Power BI · Looker Studio · Matplotlib · Plotly · Google Sheets · Excel — plus Seaborn	AWS (Lambda · S3 · EC2) · GCP · Docker · Linux · FastAPI · Streamlit · Gradio · Dokploy · React Native

• Data Science: Build agentic workflows (Tagger, Extractor, Consolidator) and fine-tune models for niche sectors like energy and clinical data.
• Automation: Ship end-to-end automation systems — large-scale data extraction, trade-data pipelines and automated content management via REST APIs.
• Recognition: 2024 Tableau Ambassador; contributed to The Globby's 🏆 2nd place at the WTO Small Business Champions 2026.

• Creator | AI PR Reviewer · GitHub App (Jul 2026 – Present)

  • Designed and shipped a free, bring-your-own-key GitHub App that automatically reviews every pull request for bugs, security issues, and performance problems — running entirely on GitHub Actions and costing $0 to operate, since it calls OpenRouter's free LLM models with each user's own key instead of a metered backend. Built the full pipeline solo: GitHub App auth, a Cloudflare Workers setup dashboard with a live free-model picker, encrypted secret provisioning, and automatic model fallback for rate-limited requests.
