Frontend Engineer at Permodalan Nasional Madani

May 1, 2024 - Present

Owned mission-critical internal product areas as the only frontend engineer. Built and led delivery from 1 to 4 engineers by defining domain ownership, onboarding playbooks, and a predictable release cadence that enabled parallel shipping without quality drift. Improved release reliability by converting weekly fire drills into steady releases, introducing regression hot-spot mapping, pre-flight checks, and rollback-ready discipline. Unblocked critical workflows under pressure by triaging cross-team issues, shipping a safe patch within 48 hours, and hardening the workflow afterward to eliminate repeat incidents. Standardized UI behavior via reusable patterns instead of undocumented tribal behaviors, reducing QA back-and-forth and shortening feature delivery time. Improved operational efficiency by mapping end-to-end financing/reporting journeys with Ops teams and redesigning edge-case handling to reduce support escalations and manual reconciliation effort. Performance-focused improvemen

Frontend Engineer at CODE.ID (UBBI-FAST Project) / Digital consulting firm delivering large-scale banking platforms

March 1, 2023 - May 1, 2024

Helped ship a real-time interbank transfer experience for UOB on Indonesia’s BI-FAST rail, translating strict compliance and security constraints into a flow that feels fast, clear, and low-error even under edge-case conditions. Led fixes during late-stage testing by uncovering a failure path related to retry/timeout behavior that could mislead users after transfer attempts; drove a cross-team UI messaging and recovery-path fix to prevent high-risk release blocking and stabilize the end-to-end journey. Built a bank-grade interaction system with consistent validation, secure input patterns, error handling, and recovery states adopted across multiple modules so teams could deliver new screens without re-inventing critical behaviors. Hardened the UI against production-like scenarios (network drops, partial failures, delayed confirmations, and state mismatches) to reduce repeat issues and make transfer outcomes unambiguous and auditable for users and operations. Participated in cross-mod

Frontend Engineer at Rebelworks / Digital agency delivering enterprise and consumer web platforms

February 1, 2021 - February 1, 2023

Delivered frontend features across multiple client projects in a fast-paced environment while balancing feature delivery with long-term code quality. Implemented unit and end-to-end testing using Cypress, increasing regression coverage and reducing post-release bugs by ~35%. Collaborated with product, design, and engineering teams to define clear, well-scoped deliverables and avoid unnecessary technical complexity.
