i'm currently a software engineer at 
keychain, where i build ai-powered data pipelines, classification systems, and internal dashboards. previously, i interned at 
mastercard automating test suites for global payment platforms.
i care deeply about shipping fast and building things people actually use. i published 
light-hooks, an open-source npm package with 18 react hooks, and built 
cauldron, a video generation tool that hit 100k+ views in its first month. beyond personal projects, i've delivered 15+ client projects under nda.
experience04
- own production data pipelines on the data team — prefect flows on aws ecs and temporal workflows on eks for enrichment, ingestion, and ai-driven product retagging.
- migrated a multi-terabyte media archive to s3 with size-checked exports and full reconciliation.
- built ai-powered classification systems using openai embeddings and llm inference for manufacturing process tagging in the cpg industry.
- engineered a data ingestion pipeline processing 8gb+ retail datasets for retailer-brand relationship mapping with chunked streaming i/o.
- automated end-to-end test suites for global payment processing platforms, improving release confidence and qa velocity.
- enhanced testing infrastructure with reusable test fixtures and ci integration for continuous regression testing.
- built web scrapers and csv analysis tools for cpg product data validation and transformation.
- developed internal dashboards for data processing, reporting, and supplier data monitoring.
- developed a next.js crypto trading app (infora) with a movable dashboard component, integrating 6+ interactive widgets for dynamic user customization.
- optimized firebase reads by ~30% for the brkt project, documenting scalable solutions that improved system performance.
- improved ux for 10,000+ active users of a betting app (hookt) by integrating web3 payments and upgrading the interface.
- collaborated with a team of 3 developers to integrate rest apis, streamlining data flow across the platform.
