About

I create dynamic, full-stack applications using Python

Hello! I'm Hilman, a Python Developer and Data Engineer with a passion for building efficient, scalable data pipelines and solutions. I specialize in transforming raw data into actionable insights by designing robust ETL processes and optimizing data workflows for high performance. With a strong focus on data integrity and a commitment to clean, maintainable code, I thrive on solving complex data challenges and enabling seamless data integration. Outside of work, I continuously explore new tools and technologies to stay ahead in the rapidly evolving world of data engineering. Whether it's architecting a scalable data platform or fine-tuning pipelines for real-time analytics, I am dedicated to delivering excellence in every project.

Projects

AI Chat Assistant

An intelligent English-learning chat assistant built with Python, powered by Google Gemini and Whatsapp API. This AI-driven tool engages users in real-time conversations to boost language skills, offering grammar tips, vocabulary suggestions, and natural dialogue flow. A perfect blend of AI, backend engineering, and educational innovation.

Netflix Clone

A dynamic Netflix clone crafted with Django and PostgreSQL, designed to mirror the look and feel of the popular streaming giant. Features include user authentication, movie/show browsing, and a sleek UI for an immersive viewing experience.

Spotify Clone

A full-featured Spotify clone built with React and Django, replicating the sleek UI and core functionalities of the original platform. Enjoy seamless music browsing, playback, and playlist management in a responsive, modern interface.

Modern Blogging Platform (On-Going)

A full-stack blogging platform built with Python, React, and PostgreSQL — designed for seamless writing, smooth performance, and a clean user experience from backend to frontend.

Diabetes Prediction Web App — Built with Flask

A project that predicts diabetes using machine learning. Built with Flask, starts with EDA and feature engineering to prepare public health data. Multiple models (KNN, SVC, Random Forest, Logistic Regression, Decision Tree) were trained and evaluated, with the most accurate one deployed in the app.

Movie Recommendation System

An intelligent app that personalizes anime suggestions based on user activity. Powered by real-world data from MyAnimeList.com, this project delivers tailored recommendations to enhance user experience and engagement.

End-to-End Data Pipeline with GCP

This project simulates the real-world workflow of a data engineer using the Google Cloud Platform. It starts with collecting data from APIs, followed by smart data modeling and ETL processing: raw data is ingested into Google Cloud Storage, transformed through intuitive pipelines built with Mage AI, and then loaded into BigQuery for efficient querying. Finally, actionable insights are visualized using Looker Studio, closing the loop from ingestion to impactful data storytelling.

Realtime Data Streaming Pipeline

This real-time data streaming pipeline fetches data from APIs and processes it using a robust tech stack: Apache Airflow, Python, Kafka, Zookeeper, Apache Spark, and Cassandra—all orchestrated within Docker containers. Designed for high-throughput, low-latency data flow, this project is a testament to end-to-end streaming architecture and real-world big data engineering.

Will AI Replace Humans? A Glimpse Into the Future of Work and Society

Hilman - 2024

I’ve often wondered about the impact AI will have on our lives and careers. While it’s true that AI is reshaping industries, I believe it’s less about replacement and more about transformation. AI can take over repetitive tasks, freeing us to focus on creativity, strategy, and empathy—things that make us uniquely human.
