🔭 Current Focus & Writing

I am getting back to open-source and writing engineering deep-dives.

• [LIVE] GitHub Repos Recommender — A client-side semantic search engine running in the browser (WASM + Metric Learning) - demo.
• [COMING SOON] RL in LLMs — A deep dive into TRL, FunctionGemma, and GRPO.
• [CLASSIC] StyleGAN-Encoder — One of my earlier contributions that gained traction in the Generative AI community.
