About me

FULL-STACK BY EXPERIENCE.FRONTEND BY INSTINCT.

I began my professional journey in November 2020. Working across the stack has given me a practical understanding of how complete products are designed, built, and maintained.

Frontend engineering remains my primary focus, where architecture, visual detail, performance, and user experience come together.

Think clearly

Understanding the problem before committing to a solution.

Build thoughtfully

Writing maintainable code with attention to every detail.

Learn continuously

Staying adaptable through deliberate, hands-on learning.

Experience

Built inproduction.

A career shaped by production banking systems, internal platforms, and a sustained focus on thoughtful frontend engineering.

Production banking platform

Contributed to M2U Web and internal banking platforms where reliability, maintainability, and delivery discipline matter.

Frontend-led full-stack delivery

Strongest in frontend engineering, with enough backend context to shape practical product and API decisions.

Testing-minded growth

Keeps sharpening through React, backend JavaScript, automated testing, CI/CD, and Storybook-oriented workflows.

Field notes

Production field notes.

Short notes on how I approach opaque, high-stakes product work without exposing confidential details.

Rescuing ambiguity before code

Context: Backoffice work often starts with scattered operational rules, edge cases, and handoffs.
Move: Map user flows, failure states, and API expectations before committing to the interface.
Signal: Less rework, clearer handoff, and UI behavior that matches real operations.

Keeping banking UI reliable

Context: Financial products punish small inconsistencies, especially around state and recovery.
Move: Favor predictable states, guarded interactions, and regression-friendly component structure.
Signal: Stable experiences that are easier to maintain across production releases.

Turning learning into delivery

Context: New tools only matter when they improve shipped work, not just the stack list.
Move: Use focused prototypes to validate patterns before they enter production code.
Signal: Learning compounds into cleaner implementation choices and better team conversations.

Proof of work

Production work.Validated learning.

A mix of production systems, confidential backoffice delivery, a critical web product, and structured Dicoding learning paths.

Confidential systems

Backoffice platforms

Delivered multiple internal backoffice projects where reliability, maintainability, and operational clarity mattered more than public visibility.

How I work

End-to-end context.
Frontend precision.

My full-stack background allows me to make frontend decisions with a clear understanding of APIs, backend constraints, and the broader product architecture.

I focus on building interfaces that are accessible, performant, maintainable, and genuinely useful to the people using them.
