statement
I am an undergraduate informatics engineering student who ships complete products alone — the automation that feeds them, the backend behind them, the interface on top, and the deploy. Seven systems so far, four of them live right now.

- 4.00 / 4.00 on transcript GPA — Bachelor of Informatics Engineering, Universitas Kristen Maranatha, 2025–2029
- 7 systems running designed, built and operated solo; four of them live right now and still being changed
- 5 placed national and international competition placements, including a BRICS Industrial Innovation Excellence Award
- Solo credit stated development on every project, including the three competition systems entered with teams — concept and pitch were shared
Drawing register
- 03 RoUniverse An autonomous publishing platform for Roblox guides and code lists. The codes index currently tracks 417 codes across 592 games, and the same pipeline runs a second brand on its own domain. 417 · codes tracked with source and check date Production · ad-funded Two brands live 2026
- 04 LoveMyFile A suite of 18 PDF tools, 11 image tools and 11 utilities that processes files entirely on the device, so there is no upload path and no server compute that scales with usage. 40 · browser-side tools shipped Production · privacy-first Live · 40 tools 2026
- 05 HustleNumbers A static suite of 38 calculators and three document generators for freelancers, consultants and marketplace sellers — built with no framework and no server at all. 38 · public tool pages Production · ad-funded Live · tax tools held back 2026
- 06 IRIS Intelligent Rice Integrated System: an IoT water-level reading, the safe-AWD stage rules, the official rain forecast, a five-class leaf screen and a plot assistant in one human-reviewed workflow. It recommends; the farmer or extension officer decides. 0.9784 · held-out accuracy, five-class leaf screening (public dataset, n = 1,621) Research prototype · three-person team, development solo Prototype · field validation pending 2026
- 07 LittleStory An early-childhood documentation app: the teacher speaks about the day, the server transcribes and structures it into per-child observation cards and a plan for tomorrow, and nothing reaches a child's record without the teacher reviewing and saving it. 178 / 78 · app and server tests green in the project's last recorded cycle Competition prototype · ICIECCE 2026 · team entry, development solo Working prototype · teacher study planned 2026
- 08 StickHive A course-notes app for students in several roles at once: type it, paste messy text and let the AI structure it, or record a lecture. It reads the campus Moodle schedule so the AI knows real deadlines and course names instead of guessing them. 3 · input methods: manual, AI-structured paste, voice or upload Competition prototype · INSPIRE 1.0 · team entry, development solo Competition prototype 2026
- 09 ClipAI An autonomous pipeline that read a long recording, chose the segments worth keeping, cut and reframed them, burned synchronised subtitles and published to three platforms. It worked, and I stopped it after six months. 6 months · built and operated Discontinued · stopped by decision Discontinued — the premise did not hold 2025

A short version
I started building things that had to survive contact with real users rather than with a rubric, which is a different and much less forgiving teacher. The systems below are all built solo, four are live right now, and all of them are still being changed.
