Sina Tavakoli
Software, Data, and AI Engineer
Cross-functional technical profile spanning software systems, data workflows, analytics, applied machine learning, and AI-enabled products. I build practical systems that connect reliable engineering, structured data, and evidence-driven decision making.
Data & Analytics
ETL/ELT pipelines, SQL modeling, Airflow orchestration, PySpark transformations, dbt models, BigQuery, validation checks, dashboards, and analytical reporting.
Applied AI
Forecasting, NLP, recommendation systems, BERT-family embeddings, TensorFlow/Keras, MLflow tracking, feature engineering, model evaluation, and LLM-assisted product flows.
Selected Work
Projects with technical depth.
A balanced portfolio of applied systems, data products, analytical workflows, AI experiments, cloud-oriented delivery, and user-facing technical tools.
Applied AI System
End-to-end weather intelligence application combining data retrieval, feature engineering, sequence modeling, experiment tracking, Streamlit delivery, LLM summaries, and cloud-ready infrastructure.
Data Product
Cloud-based retail analytics workflow that moves raw transaction data through storage, orchestration, transformation, validation, warehouse delivery, and business reporting.
Forecasting Workflow
Energy-market analysis and forecasting workflow combining cloud storage, orchestration, transformation, modeled warehouse layers, Prophet forecasts, and BI delivery.
NLP Experiment
Transformer-based text classification study that benchmarks BERT-family embeddings, neural classifier heads, imbalance strategies, and evaluation diagnostics for Reddit popularity prediction.
AI Product
Semantic recommendation application that turns natural-language reading intent into embeddings, retrieves relevant books, presents results in Streamlit, and logs feedback for improvement.
Analytical Modeling
Customer behavior analysis workflow that prepares transaction data, builds unsupervised segments, visualizes structure, and evaluates cluster quality.
Exploratory Analysis
App-market analysis workflow that cleans Google Play metadata, converts mixed-format fields, aggregates category-level behavior, and creates interpretable visual outputs.
Computer Vision System
Classical computer-vision workflow that detects circular traffic signs using C++, OpenCV, grayscale preprocessing, Canny edge detection, and Hough Circle Transform.
