Official profile of Etrio Widodo, an Indonesian Software Engineer, Java Spring Boot Developer, Backend Engineer, Technical Lead, Cloud Developer, and AI workflow builder.
A profile shaped by production systems: government platforms, banking microservices, reporting systems, cloud migration, and AI-enabled tools.
Etrio Widodo is a Software Engineer, Senior Backend Developer, Java Spring Boot Developer, Backend Engineer, Full Stack Developer, Technical Lead, Cloud Developer, and AI workflow builder based in Sukabumi, Indonesia.
I focus on systems that have to keep working after the demo: clean backend flows, strong data models, traceable integrations, and teams that know what they are building.
My work spans Java Spring Boot, PHP CodeIgniter/Yii2, Python Django, Golang Echo, PostgreSQL, MySQL, Oracle, Redis, RabbitMQ, Elasticsearch, Jenkins, Docker, AWS, GCP, MinIO, and local-first AI tooling.
Senior developer and chapter leader work at PT IDstar, with a broader portfolio spanning DAKNF, CMS Simkari, Caklur, LMS XL Smart, PMS, and integration-heavy enterprise/government workflows.

What I Actually Build
Enterprise backend systems, Java Spring Boot services, approval workflows, reporting engines, local-first applications, async synchronization, background workers, API testing tools, Android tooling, and internal automation that makes operational work faster and easier to trace.
Domains I Know
Performance management, LMS data flows, government finance reporting, DAK Non-Fisik, CMS Simkari, Caklur modules, lease-network workflows, HR/performance planning, document-heavy workflows, and Play Store-ready Android tooling.
Architecture Taste
I prefer systems with clear local data ownership, observable sync status, retryable background jobs, clean audit trails, predictable database design, and integrations that fail loudly with reasons people can act on.
Professional Values and Vision
I value traceability, calm delivery, data correctness, and maintainable architecture. My professional vision is to build software platforms that are understandable to users, operators, and future engineers, especially in government, enterprise, cloud, and AI-assisted workflows.
Featured Projects
Systems with real operational weight.
Selected work across government finance, CMS Simkari, Caklur modules, LMS XL Smart workflows, and PMS/performance platforms. The focus is practical delivery, maintainability, and traceable integration.
SIKD DAK Non-Fisik / DJPK Ministry of Finance
Problem / context: Government finance reporting and synchronization modules that require accurate data, validation, reporting, and audit-friendly workflows.
Role: Senior developer handling backend logic, reporting behavior, data checks, and issue investigation.
Stack: Python Django, PostgreSQL, Celery, SQL reporting, government data integration.
Value: Improved traceability of data issues and supported safer reporting flows for operational users.
Problem / context: Enterprise LMS and lease-network workflow platform involving payment review, data cleanup, integration checks, and operational support.
Role: Backend and integration troubleshooter for LMS flows, AF Online, lease/subduct behavior, database checks, and Camunda-related cleanup.
Problem / context: Performance planning, measurement, reporting, and evaluation platform for the Ministry of Health, covering KPI dashboards, indicator distribution, performance assessment, reporting, and performance-tree views.
Role: Backend and fullstack developer implementing dashboard modules, the unified Kemenkes visual system, template icon library, and production deployment flow.
Value: Unified the internal and public performance dashboards under one Kemenkes design system with consistent KPI cards, icons, and production-ready release checks.
Domain: Government health performance management platform.

DAK Fisik — Interkoneksi SIKD (E2E)
Problem / context: End-to-end reconciliation and evidence module for DAK Fisik that interconnects the Kementerian Kesehatan platform with SIKD/DJPK Ministry of Finance data, joining pagu/RK, contract, disbursement, absorption, output, and geotagged field-photo evidence into one drill-down view.
Role: Backend and fullstack developer building the bucket-once aggregation that keeps table totals equal to KPI cards, per-contract/output rows, per-pemda pagination, the photo summary modal with Leaflet map and clustered geotags, and the server-side DJPK photo proxy with HTTPS normalization and 24-hour cache.
Value: Made DAK Fisik realization auditable end to end: every rupiah in the table reconciles with the KPI cards, and field photos can be traced to the exact contract, output, and location.
Domain: Government budget realization and field-evidence platform.

The patterns I return to when systems need to be trusted by users, operators, and future maintainers.
Clear data ownership
Local data, source-of-truth boundaries, and integration responsibility should be explicit.
Traceable integrations
Every external call should be observable enough to explain what happened and why.
Observable background jobs
Async work needs status, logs, retry counters, and error reasons that users can act on.
Retryable sync processes
Failures should be recoverable without manual guessing or unsafe data edits.
Audit-friendly workflows
Approval, reporting, and financial flows need history that can survive real review.
Practical documentation
Docs should explain how the system runs, fails, deploys, and gets fixed.
