LLM fundamentals, fine-tuning experiments, and building reliable AI systems.

I am a Senior ML Engineer who builds and ships production generative AI systems, from image enhancement pipelines to multi-agent systems. At Jiffy, I build the core image enhancement pipeline, architect multi-agent editing systems and deploy custom ML/LLM models at scale.

💼 Current Work

I work at the intersection of computer vision and LLMs, building production AI systems that drive business impact. My background in computational geophysics keeps me grounded in first principles and pragmatic experimentation.
