What I do

Backend architecture for systems that can't go down.

I lead engineering teams, make the architecture calls, and stay close to the code. My work spans SaaS products for POS, CRM and workflow automation, and data platforms used by fisheries programs across Southeast Asia.

Multi-tenant SaaS architecture

Modular Django REST services shared across many clients, with role-based access control and scoped queries so every tenant sees only its own data.

Performance tuning

Query optimization, replication, load balancing and monitoring on production databases.

Offline-first data sync

Factory systems that keep working without internet and reconcile with central servers later.

GIS vessel monitoring

Live tracking dashboards built on SPOT Trace, plus spatial analysis and NDVI mapping.

Technical leadership

Code reviews, architecture decisions, and steady delivery with frontend, QA and product.

Fisheries supply-chain traceability

An offline-first traceability system I designed at MDPI follows tuna from vessel to export. It ran in 6 processing facilities across Indonesia, Vietnam and Thailand, and its data fed national stock assessments for Indonesia's Ministry of Marine Affairs and Fisheries.

Work history

Eight years building tech for NGOs and the ocean.

From 2015 to 2023 I worked inside international NGOs and fisheries programs, building data systems for remote islands, factory floors and boats with no reliable internet. That field experience shapes how I build SaaS today.
