Engineering behind the work.
Detailed technical approaches linked to real case studies—not a generic stack of buzzwords. Explore how I design backend APIs, data pipelines, AI retrieval, cloud delivery and dependable product systems.
ENGINEERING PRACTICE
Backend API & Systems Engineering
I design and implement application backends that treat data integrity, permissions and recovery as product requirements—not afterthoughts.
See case-study evidence ↗ENGINEERING PRACTICEData Pipelines & ETL Engineering
I build data flows that people can reproduce, reconcile and trust—from raw events to documented analytical models.
See case-study evidence ↗ENGINEERING PRACTICERAG & AI Backend Engineering
I treat AI retrieval as a backend security and data-quality problem, with model choice only one part of the system.
See case-study evidence ↗ENGINEERING PRACTICEAWS Cloud & DevOps Engineering
I design deployment and cloud operations around availability goals, least privilege and the team that will maintain the system.
