Senior Backend Developer & Technical Lead
Building reliable backend systems for public service, finance, cloud, and AI.
A profile shaped by production systems: government platforms, banking microservices, reporting systems, cloud migration, and AI-enabled tools.
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, delivering enterprise systems for ANTAM, XL, Ministry of Health, Ministry of Finance, Attorney General's Office, and AI Portal initiatives.
Enterprise backend systems, approval workflows, reporting engines, local-first applications, async synchronization, background workers, API testing tools, and internal automation that makes operational work faster and easier to trace.
Performance management, LMS data flows, government finance reporting, DAK Non-Fisik and Caklur modules, e-Renggar planning/reporting, banking microservices, document-heavy workflows, and Play Store-ready Android tooling.
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.
I move from investigation to implementation quickly: read the real source, verify with logs and queries, keep deployment risk visible, document the flow, and leave enough context so the next engineer can continue without guessing.

A compact view of roles and systems from the CV, focused on credibility and technical breadth.
Senior Backend Developer, Chapter Leader, and Project Manager delivering backend services, integration-heavy systems, reporting workflows, and AI-assisted platforms. Focused on clear ownership, reliable releases, and practical technical leadership across Brankas Antam, XL Newxlife, e-Renggar v2, ALADIN, SIKD DAKNF, and AI Portal Sukabumi City.
Delivered backend and senior development work for banking microservices, Ministry of Finance systems, Attorney General's CMS, and Bank Permata EBCP, with emphasis on service reliability, data correctness, and maintainable implementation patterns.
Contributed to banking microservices, ALADIN, Attorney General's CMS, and Spring MVC systems by building backend features, supporting integration work, and improving delivery readiness for enterprise users.
Senior developer for public-sector systems including SIMKARI CMS, DAK Non-Fisik Reporting System, SPPTI integration, health certification systems, and DJPK monitoring platforms. Worked on reporting accuracy, data flows, and workflows that support operational review.
Built the early foundation through education and public-sector systems including PPDB, AIEM PAS SMK, online diploma certificate systems, and training information systems, developing strong habits in database-backed workflows and user-focused delivery.
Hands-on across backend, data, DevOps, cloud, AI, and delivery management.
Useful for teams that need senior backend judgment, clearer system direction, or help turning messy integration work into something controllable.
The patterns I return to when systems need to be trusted by users, operators, and future maintainers.
Local data, source-of-truth boundaries, and integration responsibility should be explicit.
Every external call should be observable enough to explain what happened and why.
Async work needs status, logs, retry counters, and error reasons that users can act on.
Failures should be recoverable without manual guessing or unsafe data edits.
Approval, reporting, and financial flows need history that can survive real review.
Docs should explain how the system runs, fails, deploys, and gets fixed.
