01 / THE WAY I WORK

Good questions.
Better possibilities.

I’m an AI and product engineer working across
machine learning and full-stack development.
Digital identity, healthcare, and everyday operations.

A discussion around a whiteboard and laptops at the Lintasarta office — A discussion at Lintasarta.IN THE MAKING ↗

CURRENT CHAPTER

From the whiteboard
to the real world.

At Lintasarta, I build digital identity workflows: ID verification, liveness detection, face matching, and the systems that connect them.

What keeps me interested is the space between understanding a problem and building something that helps.

Akualita · Internal Applications

Two applications.
Connected operations.

During my internship, I proposed a letter management app to replace requests over WhatsApp and manual numbering in spreadsheets. A second app brings travel budgets, approvals, and settlement into the same platform.

Sole developer, from discovering the problem and gathering stakeholder feedback to full-stack development, deployment, and maintenance.

Full-Stack Web Developer Facilitator
Coding Camp powered by DBS Foundation
FEBRUARY — AUGUST 2026

An online instructor-led training session with Coding Camp participants and Hamza as facilitator for class CFC-05 — A learning session with class CFC-05.LEARNING, TOGETHER.

Show up. Listen.
Help the next step happen.

I supported 25 students through technical questions, weekly consultations, and the moments when learning gets difficult. That also meant tracking progress and identifying students who needed support early.

Students supported: 25
Cohort graduation rate: 88%
16 weekly consultations: 4.89/5
15 ILT sessions assisted: 4.90/5

A heartfelt thank you to Hamza Pratama, my facilitator, for your guidance, encouragement, patience, and unwavering support throughout this journey.
