Freelancer Overview

Fullstack Web & Mobile Developer with 6+ years of experience building high-complexity digital products — from banking apps and payment gateways to AI Agent platforms and real-time systems. Proficient in JavaScript, TypeScript, React, Node.js, Flutter, and modern AI tools including LLMs and the OpenAI API. I have hands-on experience working alongside AI systems — leveraging tools like ChatGPT, Copilot, and custom AI Agents to accelerate development, improve code quality, and automate workflows. This daily interaction with AI has given me a practical understanding of how models behave, where they excel, and where human input is critical — making me well-suited for AI training, prompt evaluation, and data labeling tasks that require both technical knowledge and real-world context.
