Hi this is biliartag and you can call me by Billy or Cosmas. I am a Computer Science graduate who currently working as a Software Engineer.
Graduated by late 2021, I've been working for 3+ years as Software Engineer. Currently working as a Software Engineer at Salam Pacific Indonesia Lines since 2025. Compiling Java programs, also doing side-projects using Laravel and Flutter applications👀.
Salam Pacific Indonesia Lines (PT. SPIL) (2025 - present)
Currenty working for PT. SPIL as their Software Engineer (supervisor/team leader in term of position, but goes as just another Software Engineer) from the start of 2025. Handling their main internal business application using Java stack (enterprise-y right?).
Tancorp (2024 - 2025)
Was working as a Software Engineer (well, more as a real Full Stack Engineer) from the start of 2024. Most of the projects ae Laravel and Flutter projects, and not closing any opportunity to learn other things. Have handful number of projects to handle. Some good remarks such as publishing app to Apple's App Store and Google Play Store from scratch, manage LXC containers in Proxmox to host Laravel projects using Debian, and many more...
Techanic (2022 - 2023)
Hired at Techanic as a Full Stack Engineer and assigned for Laravel and Flutter (at the end, Flutter is the main job for me LOL), from mid 2022 to Q3 of 2023 (for a year and few months). We built 3 Flutter apps and successfuly published them on Apple's App Store and Google Play Store, with probably 100+ customers(??) were using the system. Terminated due to company's funding problem. It was a solid team in my opinion (●'◡'●).
Institut Sains dan Teknologi Terpadu Surabaya (iSTTS) (2021-2022)
Working for iSTTS (my campus) during internship period, about 5 months, built a website using Laravel stack. Visit the website here, eventhough it is no longer used anymore 🥺.
Some skills that I proud of:
- Mobile Dev. (Flutter - Android and iOS)
- Web Dev. (Laravel, Filament)
- Machine Learning (making models for computer vision, they are cool-cool)
- Writing (documenting, tutorials, etc etc)
