Hi,I'm
BravelyDirgayuska
I build full-stack products end to end — documented, tested, and deployed — on a Computer Engineering foundation in hardware and networking.

Who I am
I'm a Computer Engineering graduate who gets genuinely excited about learning new technology and going deep on software, and about everything around the code: the environment it runs in, how it's deployed, and what keeps it maintainable.
What sets me apart is range. I work end to end: proper documentation, a real SDLC from requirements to release, and testing that catches problems before users do. And because my degree is Computer Engineering, I also come from the layers underneath. I've designed a PCB, written firmware for a microcontroller, and studied how traffic gets routed, so the web apps I build rest on an understanding of what they actually run on.
- Build
- Full-stack products, from schema to interface.
- Document
- READMEs, test plans, and manuals others can follow.
- Test
- Automated and written tests, not a manual click-through.
- Ship
- SDLC discipline through CI and deployment.
- Hardware
- Firmware in C, sensors, and a custom PCB design.
- Network
- IP addressing, routing, and switching fundamentals.
From screen to silicon
A full stack in the literal sense: the interface at the top, the hardware at the bottom, and the layers I've worked in between.

- Test plans (UT / IFT / BCT)
- READMEs
- SOPs
- Postman
Delivery
Commit to production with CI and reproducible setups.
- Git & GitHub
- GitHub Actions
- Docker
- Vercel
- Railway
Network
How the data actually gets there.
- IP addressing
- Routing & switching
- LAN / Wi-Fi troubleshooting
Hardware
Firmware in C, down to the PCB it runs on.

Featured work
Production software in daily commercial use, recent full-stack builds, and embedded hardware.
SITOMAS Kresno
Point-of-Sale & Inventory System
A production system now in daily commercial use at a gold jewelry retailer, unifying sales, purchasing, stock, pawning, repair services, and receivables into a single workflow.
- Barcode scanning and printable invoices across the full sales workflow
- Weight-based gold pricing per karat, buyback valuation, and monthly pawn interest with auto-generated installment schedules, plus consolidated financial reporting
- Secured with Supabase Auth, Row-Level Security, a server-verified PIN gate, and idle auto-logout
Relay
Project & Task Management Platform
Built as a product-engineering assessment: a PM runs projects, tasks, and dependencies across an internal team, while clients get a read-only, masked view of their progress.
- Drag-and-drop task board with dependency tracking, cycle detection, and a daily standup summary
- RBAC + ABAC authorization, row locks, and optimistic versioning so concurrent edits are rejected instead of silently overwritten
- Unit and end-to-end tests running in GitHub Actions CI; frontend on Vercel, API on Railway, audit trail made immutable by Postgres triggers
AppointMe
Timezone-Aware Scheduling App
Appointment scheduling across timezones: every time is stored in UTC, shown in each viewer's own zone, and only bookable when it falls inside working hours for everyone involved.
- Validates 08:00–17:00 working hours against every participant's local time, organizer included
- PostgreSQL with Prisma migrations and seed data, with the local database running in Docker
- Pinned Node version and step-by-step setup docs, so the project runs the same on any machine
Bearion
Full-Stack E-Commerce Platform
A bilingual storefront for a clothing brand with a complete order lifecycle including cancellation and shipment tracking, plus an admin dashboard for products, pricing, and promotions.
- PayPal integration with server-side capture verification, plus manual bank transfer with admin-verified proofs
- Multi-courier shipping rates and tracking, with live IDR/USD conversion
- Secured with role-based access control and PostgreSQL Row-Level Security
November Coffee
Cafe Management System
Multi-shift employee attendance tracking, automated payroll calculation with salary-slip generation, and real-time inventory management.
- Scheduled operations running through automated cron jobs on Vercel
- OCR-powered receipt processing that extracts data from photographs automatically
- Role-based authentication and a three-shift system with WIB timezone handling
ICE Logger
Internal Combustion Engine Data Logger
Final-year project: a multisensor data-acquisition system monitoring real-time engine performance across RPM, torque, fuel consumption, temperature, and airflow.
- Custom 2-layer PCB with modular RJ45 sensor connectors and signal-conditioning circuitry
- Five sensor types integrated via ADC modules and an ATmega328P microcontroller
- Sensor calibration and functional testing, with real-time output via LCD and UART serial communication to a PC
