Building the data layer that powers intelligent systems.

Currently at MTA — building AI-driven data systems across healthtech, finance, and government. I design production-grade data pipelines, lakehouse architectures, and secure integration layers that let AI agents operate on real-world, regulated datasets without compromising compliance.

Previously at Eureka AI (Abu Dhabi) as both Backend Engineer and Data Scientist — shipping third-party API integrations and ML forecasting models. At OJK(Indonesia's financial regulator), I built audit-grade Tableau dashboards over SQL Server. I also mentored ML cohorts at Bangkit Academy backed by Google, GoTo, and Traveloka.

I work at the intersection of AI and data infrastructure: real-time CDC streaming, workflow orchestration, lakehouse platforms, and secure AI agent integrations. The briefs I gravitate toward are hard — regulated data, multi-tenant streams, and production systems where failure is not an option.

02 / Services

What I can build for you.

Data pipelines, AI agents, production ML, and full-stack platforms — from architecture to deployment.

01

Data Pipeline Engineering

Production-grade data infrastructure for AI-native applications — real-time ingestion to analytical layers.

Real-time CDC streaming (Debezium + Kafka + Pub/Sub)
Lakehouse architecture (Iceberg + Spark + StarRocks)
Workflow orchestration (Temporal, Netflix Conductor)
Multi-tenant Postgres synchronization
