Leading sole development of a full-stack web application for a major automotive finance company, digitizing workflows that previously relied entirely on Excel and manual processes.

What I built:
- Architected the full system from scratch (frontend, backend, database schema, and admin tooling) as the sole developer
- Built a PWA with offline-first capability to support field sales agents operating in low/no-signal areas, ensuring zero data loss during disconnected sessions
- Engineered a dynamic function execution system where business logic is authored in the admin panel as JavaScript, stored as strings in the database, and evaluated client-side, enabling non-engineers to update calculation logic without a deployment cycle
- Developed an internal admin panel using refine.dev and Material UI for data management and operational workflows
- Built the customer-facing interface with Tailwind CSS and DaisyUI, focused on responsive design and usability across devices
- Integrated Supabase for authentication, database operations, and API layer

Impact: Replaced a fully manual, Excel-based operation with a scalable web platform, dramatically reducing processing time and human error across the sales workflow.

One of the longest-tenured frontend engineers on Blibli's Product Detail Page (PDP), one of the highest-traffic surfaces on the platform. Joined during the earliest stage of the PDP revamp, before a design system existed, and stayed through every major architectural evolution until resignation.

What I built & led:
- Contributed across hundreds of features over 5 years, spanning the full product lifecycle from planning to production
- Participated in the full PDP revamp, from legacy UI with no design system, through to a modern, design-language-aligned interface
- Drove major stack migrations: Vue 2 → Vue 3 (Composition API), Webpack → Vite, unit testing → integration testing (Playwright)
- Implementation of above-the-fold SSR, bringing Core Web Vitals from red to green, a direct business impact, as CWV is a Google ranking factor that influences search visibility and organic traffic. For a high-traffic e-commerce PDP, better CWV means higher search ranking, more organic visits, and ultimately more conversions.
- led development of the platform's first reusable Add to Cart Module, a cross-page component that encapsulates the full purchase flow, with the majority of implementation done independently
- Conducted code reviews as part of a mandatory 2-reviewer merge policy, maintaining code quality across the team
- Mentored interns, participated in frontend hiring interviews, and served as the go-to engineer for onboarding new PDP frontend engineers, a natural role given being one of the most tenured engineers on the team

I collaborated closely with frontend and backend teams, product managers, UX designers, UX engineers, data analysts, business analysts, and RnD team. It was a role that allowed me to learn how product, design, and engineering blend together to create a great user experience.

Worked as a full-stack developer on digital projects for enterprise clients in banking and insurance, including one project that became fintech infrastructure used at national scale.

Highlight - BRI Credit Card Digitization:
- Sole backend developer for BRI's credit card application system, partnering with one frontend engineer to deliver end-to-end
- Digitized a fully manual KYC and document signing process: what previously took days of physical paperwork (manual KTP/NPWP/slip gaji verification, wet signatures, postal mail) now completes in seconds
- Integrated Privy ID for digital identity verification and e-signature, automating the full applicant journey from document submission to approval
- The system, originally internal to BRI, later became the backbone for BRI's external credit card channel, including the Tokopedia Card product, used by millions of Tokopedia users

Other projects:
- Built and maintained AEM components for AIA Indonesia supporting corporate website and digital campaign workflows
- Delivered AEM pages for CIMB Malaysia aligned with regional and global brand standards
- Built full-stack campaign and registration platform for Wunderman Thompson Indonesia (Node.js, Express, MongoDB)
- Developed a data warehouse for British American Tobacco Indonesia, integrating APIs, databases, and Excel sources via Azure Functions

It was a role where I got to collaborate with different teams, troubleshoot complex issues, and learn how enterprise systems operate at scale.
