I’m Aarjun Mahule, an aspiring Data Scientist & AI Engineer passionate about building production-grade AI solutions and end-to-end machine learning systems.
I specialize in designing intelligent pipelines that collect, process, analyze, and act on data autonomously — from predictive ML models to fully automated multi-agent workflows. My work blends AI, automation, orchestration, and infrastructure to deliver solutions that scale.

I aim to build a global career that merges deep tech engineering, freelancing, and entrepreneurship, and I’m relentlessly focused on mastering the technologies that power modern AI systems.

• 🧠 AI Job Application Agent – A production-grade AI system that autonomously discovers, filters, applies, and tracks 1000+ job opportunities using multi-agent orchestration, Playwright automation, RAG pipelines, and intelligent scoring logic.
• 💳 Credit Card Fraud Detection – Machine learning pipeline with SMOTE balancing, 284K+ transactions, and a 0.99 F1-score, built for high-performance anomaly detection.
• 🐦 Wildlife Movement Prediction – GRU-based deep learning model that predicts bird migration patterns using spatio-temporal data from the Movebank API, featuring custom preprocessing and sequential modeling.

"Build relentlessly. Automate intelligently. Scale fearlessly."
When I’m not coding, I explore AI trends, study automation systems, and brainstorm ideas for the next generation of tech products.
