Open for Data Science role · 2026

I turn messy data
into decisions that ship.

Computer Science student at Soegijapranata Catholic University focusing on Big Data Analytics & AI. One year building hate comment detection, fraud detection, computer vision, and forecasting models from raw CSVs to real solution.

01 / About

A data-driven builder from Semarang.

I'am a software engineer and AI entrepreneur with a strong passion for building scalable, real-world technology solutions. As the founder of Growithm, an AI-as-a-Service platform, I focus on developing intelligent applications that help businesses automate processes and improve efficiency. My expertise includes Python, backend development, data engineering, artificial intelligence, and automation, with a strong emphasis on writing clean, maintainable, and production-ready code. I enjoy transforming complex ideas into practical products that deliver real business value, and I am continuously expanding my knowledge to stay at the forefront of emerging technologies. My long-term goal is to build innovative AI-driven solutions that make advanced technology more accessible while growing a sustainable and impactful technology company.

Beyond models, I lead people. I run a 20-person student org, produce a monthly podcast, and founded Djagokoding to help peers grow in AI. If it’s data, insight, or automation I want in.
