Product flow first
I start from user journey, business rules, empty states, error states, and API contract before polishing UI details.

About & Experience
How I build mobile products
I build mobile features by connecting product flow, API behavior, state management, and release constraints. Most of my work sits around Flutter apps that need to be reliable across Android and iOS.
Release-ready delivery
I care about build stability, device behavior, handoff quality, QA feedback, and the risks that appear near app release.
Maintainable Flutter code
I keep state management, API boundaries, local data, and UI structure readable enough for the next developer to continue.
Cross-team implementation
I work around backend, QA, product, and stakeholder constraints across banking, merchant, and internal workflow domains.

Projects
Internal Workflow App
PT. Japfa Comfeed Indonesia
Helped build Japfa's internal workflow app across mobile and web, covering form-driven task execution, approval flow, notifications, and team communication so daily coordination no longer depended on scattered third-party tools.
NoLimit Pemda
Freelance
Built a mobile monitoring app for government-facing use cases, focused on social media tracking, issue visibility, and lightweight analytics that could be checked quickly from Android and iOS devices.
Campus Services App
PT. Bank Rakyat Indonesia / Sagara Technology
Contributed to a campus services app connected to the BRI ecosystem, with work around non-academic modules such as rental, library access, and crowdfunding inside one mobile experience.
Now
A short read on what I am shipping, what I am sharpening, and the kind of work I still like saying yes to.
Current work
I am shipping mobile banking and merchant flows at Bank MAS, while still taking selected freelance work when the product scope is clear and the team moves fast.
Current edge
Right now I am leaning harder into release quality, clearer app architecture, and deeper iOS understanding on top of my day-to-day Flutter work.
Open to
I am still interested in mobile product work that needs execution strength around product flow, integration detail, and getting the app into a release-ready state.
