Senior Software Engineer & Consultant. I build tools for developers and share insights on AI-assisted coding, Astro, and modern web development. Writing in English and Spanish at valdemird.com.
What are you working on?
A side project called sprite_gen, a model that generates sprite sheets for pixel-art games (the rows of frames you use to animate a character). It's a diffusion model I'm fine-tuning to get the look right. What's your goal this week?
Getting it to a solid state. I'm running experiments to find the best settings, so the plan is to lock in the winning one, train it properly, and check how the animations actually look, then tidy up the pipeline so I can pick it back up later without relearning everything.
