Experimentation & Prototyping: Develop proof-of-concepts and experiment with new AI tools, frameworks, and technologies.
Debugging & Optimization: Troubleshoot technical issues, improve application performance, and maintain clean, reliable code.
Continuous Learning: Stay updated with developments in AI, software engineering, and modern development frameworks.
Required Skills & Experience
3-6 months of experience in software development, including internships, freelance work, or personal projects.
Good understanding of frontend technologies such as HTML, CSS, JavaScript, React, or Next.js.
Familiarity with backend development using Python, Node.js, or similar technologies.
Basic understanding of databases such as PostgreSQL, MySQL, or MongoDB.
