I work in a team of two on a full-stack web app for a major automotive finance company. It replaces sales workflows that used to run on Excel and manual steps.
What I worked on:
- Set up the system from the start: frontend, backend, database schema, and admin tools
- Built a PWA that works offline for field sales agents in areas with weak or no signal. Saves wait in a queue until the connection returns, so agents lose no data
- Designed a dynamic function system. Business logic is written as JavaScript in the admin panel, stored in the database, and run in the browser, so non-engineers can change a calculation without a deploy
- Wrote the internal admin panel with refine.dev and Material UI
- Made the customer-facing UI with Tailwind CSS and DaisyUI, responsive on phones and desktops
- Used Supabase for authentication, the database, and the API layer
Sales agents now do this work in the app instead of in Excel, which takes less time and leaves less room for manual errors.

I was one of the longest-serving frontend engineers on Blibli's Product Detail Page (PDP), one of the busiest pages on the platform. I joined at the start of the PDP revamp, before Blibli had a design system, and stayed through every major architecture change until I resigned.
What I built and led:
- Worked on nearly a hundred features over 5 years, from planning to production
- Took part in the full PDP revamp, from the old UI with no design system to a new one that follows Blibli's design language
- Drove the stack migrations: Vue 2 → Vue 3 (Composition API), Webpack → Vite, and unit tests → integration tests with Playwright
- Implemented above-the-fold SSR, which moved Core Web Vitals from red to green. Google uses CWV as a ranking factor, so this helped the page's search visibility and organic traffic
- Led development of the platform's first reusable Add to Cart Module, which handles the whole purchase flow on any page, and wrote most of the code myself
- Reviewed code under the team's rule that every merge needs two approvals
- Mentored interns, interviewed frontend candidates, and was the go-to person for onboarding new PDP frontend engineers
I worked closely with frontend and backend engineers, product managers, UX designers and engineers, data and business analysts, and the R&D team.

I was a full-stack developer on projects for banking and insurance clients.
BRI credit card digitization:
- I was the only backend developer on BRI's credit card application system and built it end to end with one frontend engineer
- The old process was manual. Staff checked each applicant's KTP, NPWP, and salary slip by hand, collected wet signatures, and sent documents by post, which took days. The new system does it in seconds
- Integrated Privy ID for digital identity checks and e-signatures, so an application goes from document upload to approval online
- BRI first used the system internally, then made it the base of its external credit card channel, including the Tokopedia Card used by millions of Tokopedia users
Other projects:
- Built and maintained AEM components for AIA Indonesia's corporate website and digital campaigns
- Delivered AEM pages for CIMB Malaysia that follow its regional and global brand standards
- Built a full-stack campaign and registration site for Wunderman Thompson Indonesia (Node.js, Express, MongoDB)
- Built a data warehouse for British American Tobacco Indonesia that pulls from APIs, databases, and Excel files through Azure Functions
