I specialize in building secure, data-driven systems, scalable backend architectures, and high-performance ETL pipelines using Laravel, Python, PostgreSQL, and MySQL.
- Data Engineering & ETL: Designing database schemas, query optimization, normalization, and robust data extraction/transformation pipelines.
- Backend Architecture: Building scalable REST APIs, microservices, and client-side zero-knowledge encryption pipelines (Web Workers / Crypto API).
- Cloud & Containers: Deploying scalable containerized environments with Docker, Kubernetes, and cloud storage integrations (S3 / R2).
