The Evolution

2023
Python Foundations

Built strong algorithmic thinking and Pythonic programming. OOP, data structures, automation scripting, API consumption.

2024
Machine Learning & AI

Explored supervised and unsupervised learning. Built and evaluated models using scikit-learn, pandas, and NumPy ecosystems.

2025
Cloud Computing & Data Science

Deployed workloads on AWS and Azure. Cloud fundamentals, storage tiers, compute services, and data-at-scale patterns.

2026 — Now
Data Engineering & Databricks

Deep-diving into Spark, Delta Lake, and the Databricks lakehouse paradigm. Building production-grade ETL and streaming systems.

Future
Data & AI Platform Engineering

Converging data engineering, analytics, and AI workloads into unified platforms. Governance, observability, and intelligent systems.

My goal is to build expertise in modern Data & AI platforms that unify data engineering, analytics, machine learning, and deployment.

I am particularly interested in how platforms like Databricks are converging traditional data engineering with AI workloads to create scalable, intelligent systems.
