RAW TO RELIABLE / LAB / PRODUCT SYSTEMS

Tools, Workflows & Product Experiments

A collection of local-first tools and engineering experiments that connect data, interfaces, automation, and human decision-making.

The Lab documents systems built to solve operational problems that do not fit neatly inside a traditional data pipeline: browser ingestion, scoring logic, workflow state, local persistence, secure integrations, and iterative interface design.

    Job Search OS

    A local-first job research and application workflow for importing roles, evaluating fit, tracking evidence, detecting duplicates, and preserving human review at every step.

    The system combines a browser extension, local ingestion service, offline scoring, SQLite persistence, application tracking, and bilingual workflow design into one review-oriented operating system for job search.
