Summary

Product-minded engineer with 4+ years bridging technical execution and product ownership, primarily in fintech. At AstraPay, operates as both product decision-maker and hands-on engineer — authoring Business and Technical RFCs (system flow diagrams, data mapping specs, ERD definitions), managing backlogs, and personally implementing solutions that drove an 83% reduction in report generation time and enabled settlements for 431+ merchants. Led product strategy across 2 streams (Reporting and KYC) for a team of 9, coordinating full SIT/UAT/PRD testing cycles and incident response while presenting executive updates directly to the CEO.

Experience

1. Product Engineer — Reporting

   PT Astra Digital Arta (AstraPay)

   Nov 2023 – Present

   Jakarta, Indonesia

   Dual role: own product direction (RFCs, flow diagrams, backlog, stakeholder alignment) while architecting and implementing core platform capabilities across SIT/UAT/PRD environments.

   • Migrated 150+ legacy NiFi-based reports from on-prem to BigQuery-backed Java Report Service, eliminating recurring monthly outages and adding version control and audit trails. Built self-service Report Admin Web so SysOps can manage schedules, recipients, and report regeneration without engineering involvement.
   • Upgraded the report scheduler from Java 11 to Java 21 with virtual threads — reduced peak thread usage by 75%, eliminated GC pressure spikes, and accelerated report generation by 83% (12 min → 2 min). Extended delivery options with an API channel alongside email and SFTP.
   • Authored Business and Technical RFCs — system flow diagrams, data mapping specs, ERD definitions — translating Finance, Operations, and Compliance pain points into precise engineering requirements with testable acceptance criteria.
   • Specified data pipeline requirements for Datastream integration (Cloud SQL → BigQuery), enabling scalable analytics while ensuring UUPDP-compliant data handling.
   • Authored RFC for a standalone ETL service to ingest user engagement data (MoEngage APIs → BigQuery), enabling behavioural analytics and automating regulatory reporting for Bank Indonesia.
   • Owned the full delivery testing cycle across SIT, UAT, and PRD — wrote acceptance criteria, ran functional validation, coordinated release sign-off. Effectively the QA lead on a team without a dedicated QA role.
   • Managed production incidents including a scheduler outage that halted scheduled merchant reports — coordinated triage, issued stakeholder updates, authored the post-mortem and corrective action plan.
   • Prioritized the platform backlog using WSJF, balancing technical debt against new feature requests across 200+ critical merchant reports. Collaborated across 5 core service teams (Auth, Payment Channel, User, QRIS, Biller) to deliver integrated features.

2. PDCA Manager (concurrent role) — Reporting & KYC

   PT Astra Digital Arta (AstraPay)

   Feb 2024 – Mar 2025

   Jakarta, Indonesia

   Concurrent planning and execution role across 2 product streams (combined team of 9) — managing roadmaps, budgets, delivery, and continuous improvement.

   • Defined and maintained the annual product roadmap using WSJF, translating business objectives into sequenced, budgeted project plans.
   • Owned end-to-end product direction for the Reporting stream (backlog, RFCs, sprints); partnered with the KYC PM on timelines, budget allocation, and cross-stream alignment.
   • Authored and presented monthly executive updates directly to the CEO, covering roadmap progress, budget utilization, risks, and strategic recommendations.
   • Facilitated team retrospectives and used SQL/BigQuery analysis to inform backlog prioritization and validate product hypotheses.

3. Platform Engineer — Infrastructure

   PT Astra Digital Arta (AstraPay)

   Jul 2023 – Oct 2023

   Jakarta, Indonesia

   • Led UAT infrastructure migration from On-Premise to GCP, coordinating environment readiness across Dev, QA, and Operations. Implemented CI/CD automation to standardize deployment and reduce environment drift.
   • Designed a Cross-Project Centralized Load Balancer, achieving 48% infrastructure cost reduction vs. decentralized architecture.

4. Product Engineer — CMS & Notification

   PT Astra Digital Arta (AstraPay)

   Oct 2022 – Jul 2023

   Jakarta, Indonesia

   • Owned the Crafter CMS platform used across the organization, enabling teams from multiple domains to create and maintain notification templates.
   • Managed the feature backlog for CMS Notification — wrote technical RFCs and acceptance criteria for push notification and OTP delivery.
   • Expanded OTP delivery from a single SMS provider to a multi-channel architecture (2 SMS + 2 WhatsApp providers), improving reliability and enabling failover for critical authentication flows.
   • Defined requirements and integrated the iOS MoEngage SDK, enabling targeted push notification campaigns.
