About me

I build systems that sit between software engineering, machine learning, and data-heavy product work.

I am also interested in research on domains like AI-ML, data or systems related to them.

I like shipping real stuff, not toy notebooks. Search systems, retrieval pipelines, ML experiments, dashboards, browser extensions, OMR tooling, finance projects, and LLM-based workflows are my lane.

What I work on

• Full stack web apps
• Machine learning and applied AI
• Research on interpretability, representation engineering, activation steering
• Search and retrieval systems
• Data analysis and analytics pipelines
• Computer vision and document automation
• Finance and market-related projects
• Browser extensions and developer tooling
