Product Owner Β· Tech Founder Β· Engineer by trade
"I don't stop at 'it works'. I ask whether it was worth building."
A Product Owner who came up through engineering. I've spent nine years building systems that a lot of people depend on β banks, hospitals, a ministry, and now schools. Because the technical background is real (Golang, Rust, infrastructure), I can price a product decision up front instead of discovering the cost after the team has already built it.
- π« Tech Founder & Product Owner at Skolain β a school management platform I founded and have owned end to end since June 2026
- π¦ Contracted three separate times for Bank Rakyat Indonesia's digital products, rising to Senior Software Engineer
- π Cut operational cost by up to 60% at Telkom β a migration I proposed from an infrastructure cost analysis, then planned and led
βοΈ Built FRAMES with the Faculty of Medicine, Universitas Indonesia and Garuda Indonesia Training Center β fatigue-risk self-assessment for flight crew- π Contributed to the technical rules for SPARING & CEMS at Indonesia's Ministry of Environment and Forestry
- π B.Sc. Information Systems, BINUS β 3.85 GPA, Magna Cum Laude. I started at a vocational high school, not the usual track
- π¬ Happy to talk about discovery, release prioritisation, multi-tenant architecture, or taking a product from zero
Most of my work comes down to one thing: making the slow fast, and making the vague explicit.

Observability & release quality
Product work & AI-driven development
Most of what I've built lives in company and client repositories β closed, as it should be. So I collected the evidence in one place instead. Every row below opens the slide that documents it.
| Product | What it is | My role |
|---|---|---|
| π« Skolain | School platform: computer-based exams, LMS, attendance, national student-data integration, report cards | Tech Founder & Product Owner |
| π₯ PrimaSejahtera | National HRIS for PT PKSS β steady when 50,000 people clock in at once | Architecture + on-premises infrastructure |
| π₯ HSE Siloam | Mission-critical safety system across every hospital unit | Software Architect, 6 engineers |
| π Telkom OCA | NestJS β Golang backend migration, 60% lower operational cost | Proposed it, planned it, led it |

The public repositories on this account are mostly coursework and experiments β the coursework ones are archived. The systems I actually build live in company and client repositories, closed, as they should be.
I don't display a GitHub stats card here, for two reasons: it only counts public activity, so it understates rather than represents; and the third-party service that renders it is frequently down. What does represent the work is oman-porto.skolain.id β 39 slides, with the artefacts and the dates.
