IDENTITY PRESERVATION INSTRUCTION:
Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics. Maintain the authentic likeness and expression while applying professional enhancements.

TRANSFORMATION DESCRIPTION:
Transform the uploaded photo into a professional GitHub developer avatar. Create a clean, modern portrait suitable for technical profiles. The subject should appear approachable, professional, and confident. Maintain natural facial features while ensuring the image is well-lit, sharply focused, and visually appealing. The final image should work perfectly as a small circular or square profile picture while retaining all identifying characteristics.

STYLE AND AESTHETIC PARAMETERS:

- Lighting conditions: Soft, even studio lighting with gentle key light from front-left, creating subtle dimension without harsh shadows
- Color palette: Natural skin tones with slight enhancement for vibrancy, neutral background (solid light gray or soft gradient)
- Background treatment: Clean, minimal background - either solid neutral color (light gray/white) or very subtle gradient blur to maintain focus on the face
- Facial enhancement: Subtle professional retouching - natural skin smoothing, enhanced eye clarity, slight teeth whitening if visible
- Clothing: Keep original attire but ensure it looks neat and professional
- Overall aesthetic: Modern, clean, tech-industry appropriate, LinkedIn-style professional

NEGATIVE PROMPT GUIDANCE:
