Core programming language for data science and machine learning

Python is my primary programming language for data science, machine learning, and backend development. I use it daily for building ML pipelines, data processing, API services, and automation scripts. Its rich ecosystem of libraries (NumPy, Pandas, scikit-learn, TensorFlow, PyTorch) makes it indispensable for end-to-end AI projects — from data ingestion and feature engineering through model training, evaluation, and deployment.

Deep learning framework

I use TensorFlow for building and training deep learning models, particularly computer vision and neural network architectures. I've applied it to object detection (YOLO-based models), medical AI fine-tuning pipelines, and classification tasks. TensorFlow's ecosystem — including Keras for rapid prototyping, TensorFlow Lite for edge deployment, and TF Serving for production — lets me move from research to deployment efficiently.

Deep learning and neural networks

PyTorch is my go-to framework for research-oriented deep learning and projects that need maximum flexibility. I've used it for computer vision models (custom YOLO implementations), semantic search embeddings, and aerial detection pipelines. Its dynamic computation graph and rich ecosystem (TorchVision, Hugging Face Transformers, FAISS) make it excellent for both prototyping and production workloads.

Machine learning library for Python

scikit-learn is my workhorse for classical machine learning — clustering, classification, regression, dimensionality reduction, and preprocessing. I've used it extensively in EEG signal analysis (KMeans, hierarchical clustering, PCA) and model comparison pipelines (Decision Trees, SVMs, KNN). Its consistent API and rich evaluation metrics make it invaluable for rapid experimentation and baseline modeling.

Computer vision and image processing

I rely on OpenCV for real-time image and video processing tasks, including camera capture, frame preprocessing, image transformations, and feature extraction. It's been essential in edge-based vision systems running on resource-constrained hardware like the Raspberry Pi, where efficient frame handling is critical for real-time performance.

Real-time object detection and computer vision

I use YOLO (You Only Look Once) for real-time object detection, having trained custom models on specialized datasets of up to 160,000 labeled images. My experience spans data collection and annotation, model training and hyperparameter tuning, edge deployment optimization, and inference pipeline integration for fire/smoke detection, aerial bird and nest detection, and security monitoring.

Data manipulation and analysis library

Pandas is my primary tool for data wrangling, cleaning, transformation, and exploratory analysis. I use it to handle structured datasets — loading, filtering, aggregating, and merging data from CSV, SQL, and other formats. It's foundational in every data-intensive project I build, from EEG signal feature extraction to ML dataset preparation.

Numerical computing and array operations

NumPy is the computational backbone of every Python project I build. I use it for multi-dimensional array operations, linear algebra, statistical computations, and as the interchange format between ML libraries. Its vectorized operations are essential for efficient numerical computing in data preprocessing pipelines and model inference.

Database querying and data manipulation

I write SQL for relational database design, complex queries, data analysis, and application backends. My experience includes PostgreSQL (via Supabase), SQL Server (Entity Framework Core), and performance optimization — indexing, query planning, and efficient join strategies for production applications.

Amazon Web Services cloud computing platform

I use AWS for cloud infrastructure, including EC2 for compute, S3 for storage, and Lambda for serverless functions. My experience spans setting up cloud environments for ML model deployment, static site hosting, and scalable backend services.

Google Cloud Platform for cloud computing and services

I work with GCP for its ML and AI services — including Vertex AI for model training, Google Colab for prototyping, and Cloud Storage for dataset management. GCP's integration with the TensorFlow ecosystem makes it a natural choice for ML workflows.

Containerization platform for application deployment

Docker is my standard tool for creating reproducible, portable environments. I use it to containerize Python APIs (FastAPI, Flask), ML inference services, and full-stack applications. Docker Compose helps me orchestrate multi-service stacks with databases, caching layers, and application servers.

Version control and collaboration

Git is my version control system for every project — from solo work to team collaborations. I use feature branches, pull requests, and conventional commits. All my projects are hosted on GitHub with CI/CD workflows, README documentation, and release management.

GPU cloud platform for AI and machine learning workloads

I use RunPod for cost-effective GPU compute when local hardware isn't sufficient — training computer vision models, running large-scale inference, and experimentation with deep learning architectures. Its pay-per-second pricing and pre-configured templates make it ideal for intermittent ML workloads.

Interactive computing and notebooks

Jupyter notebooks are my environment for exploratory data analysis, prototyping ML pipelines, and presenting reproducible research. I use them for everything from initial data exploration to generating publication-ready visualizations with Matplotlib and Seaborn.

Cloud-based notebook environment

Google Colab provides free GPU/TPU access for prototyping and training ML models. I use it for quick experiments, model fine-tuning, and collaborative notebook work. Its integration with Google Drive and GitHub makes sharing and versioning seamless.

CI/CD pipelines and DevOps toolchain

I use Azure DevOps for CI/CD pipeline configuration, work item tracking, and repository management in team environments. Its YAML-based pipeline definitions integrate well with both cloud and on-premises deployment targets.

Project management and issue tracking

Jira is my project management tool for team-based development — tracking sprints, managing backlogs, and coordinating tasks across team members. I've used it in academic and professional settings for Agile development workflows.

Team collaboration and documentation

I use Confluence for technical documentation, project wikis, and team knowledge bases. It's my go-to for maintaining living documentation alongside code repositories.

Modern, fast Python web framework for building APIs

FastAPI is my preferred framework for building high-performance REST APIs in Python. I leverage its async support, automatic OpenAPI documentation, Pydantic validation, and dependency injection system to build clean, type-safe, and well-documented backend services.
