Project Portfolio

Every project starts with an incomplete brief.

I'm an Information Systems student (Data Science concentration) working at the intersection of data and business analysis — turning raw datasets into working analysis, and ambiguous stakeholder needs into structured systems.

Project log

Four projects, in the order they were worked — each one shows both the data side and the business side of the problem.

PROJECT—01

Geography Dashboard, DVD Rental Dataset

2026

Cleaned and transformed raw customer location data from a PostgreSQL dataset, mapping countries into continental groups to surface regional trends. Built and deployed an interactive dashboard so the patterns are explorable, not just reported.

MAMARUMI — F&B Accounting & Production System

2026

Took business-process details relayed secondhand from a small F&B owner and translated them into system requirements: a double-entry accounting structure and FIFO-based batch production tracking. Built and delivered the system matching the business's actual operating flow.

WINTEQ — Predictive Maintenance Database

2026 · Astra Otoparts project brief

Given only a problem statement and expected output — no training data, no formal spec — I scoped the two real gaps myself: access structure and missing data. Designed a 3-role access structure (Operator, Teknisi, Admin), built the PostgreSQL schema and DDL for four core tables, and wrote a Python generator to produce the dataset the team's model development was blocked on. Documented the handoff for a 4-member cross-functional team.

BridgeLang — Campus Language-Learning Platform

2025 · Team project

Built the language-learning modules and produced the opening video for a 3-person-team platform helping international-campus students overcome language barriers — interactive lessons, quizzes, and stories across Indonesian, Mandarin, and Tetun, alongside real-time translation and gamified daily/weekly challenges.
