Justin Sibonga
I'm a full-stack engineer with experience designing, building, and scaling modern web applications, analytics platforms, and data pipelines—with a maintainability-first approach.
My work spans React, Next.js, TypeScript, dbt, Airflow, Snowflake, BigQuery, AWS, and Rust, combining product-focused engineering with reliable, high-throughput data systems.
01 - about
location: philippinesI design and build batch and streaming pipelines, ELT with strong modeling, observability-first workflows, and responsive web applications.
My work spans dbt and Airflow orchestration on Snowflake and BigQuery, AWS analytics stacks with Redshift, Glue, EMR/Spark, high-throughput Rust utilities, and web interfaces with React, Next.js, TypeScript, and Tailwind CSS.
I approach every project the same way: understand the data first, model the domain carefully, then build interfaces that make complexity invisible. Whether it's a dashboard tracking real-time metrics or a data pipeline moving millions of records a day, the goal is always the same — systems that are reliable, observable, and easy to change.
