About

Software engineer building usable systems at the intersection of web, AI, and data.

I'm Aristotelis Theocharoulas, a Computer Science graduate from York University based in the Greater Toronto Area. I enjoy building software that is practical, thoughtful, and clearly useful to real people.

My work spans full-stack web development, mobile apps, applied AI, and data-driven products. Recently, that has meant building AI-powered fitness and nutrition experiences, exploring intelligent personalization systems in Python, and developing structured AI support workflows for a production environment.

I'm especially interested in projects where software engineering, product thinking, and AI overlap: systems that combine strong product experiences with real technical depth and clear user value.

Current focus

I'm actively building software across full-stack product development, applied AI, and intelligent data systems. I'm open to software engineering roles, full-stack opportunities, AI-focused roles, and data/analytics positions where I can contribute meaningfully from day one.

Engineering

React, React Native, TypeScript, Next.js, Node.js, Firebase, REST APIs.

AI & data

OpenAI integrations, Python analytics, Dash, Plotly, forecasting, personalization logic.

Tools

Git, GitHub, VS Code, SQL, Jupyter, Firebase, Azure-style product workflows and cloud-backed apps.

Background

  • Education: BSc in Computer Science from York University.
