Aloysius Jebanson Berdin Mannas Rajan

I’m a Sustainability Data Engineer who transforms raw IoT and operational data into real-time insights, interactive dashboards, and certification-ready reporting. I architect end-to-end systems, from Python ETL scripts and Supabase/PostgreSQL backends to interactive React/TypeScript frontends that help teams track performance with confidence.

In my current role, I replaced manual Excel workflows with automated API ingestion for LEED Arc, built an ETL pipeline processing 28,800+ daily readings from 300+ sensors in Supabase. I also build threshold-based alerting and reporting pipelines for LEED and WELL compliance using Supabase cron jobs, supporting 100+ active projects while maintaining 100% audit-ready data deliverables.

I’m especially focused on emerging corporate sustainability frameworks like CSRD and CSRD/ESRS, continually expanding how I model emissions and reporting requirements. Beyond production systems, I’ve developed prototypes including an EU ESPR-ready digital product passport/DPP prototype, an urban equity platform, and an ESRS report generator to streamline survey-to-report workflows.
