Hey Contra,
I’m a Full-Stack Software Engineer currently taking on new freelance/contract projects. If you need a fully functional, scalable product built from scratch—whether it's a cross-platform mobile app or a high-performance web application—I can help bring your vision to life.
What I Build:
Startup MVPs: Turn your idea into a working product fast so you can launch, test the market, or pitch to investors.
Web Applications: Responsive, lightning-fast web apps with clean UI and secure backend architectures.
Mobile Apps: Cross-platform mobile applications (iOS/Android) built with robust functionality.
API Integration & Databases: Custom REST/GraphQL APIs, database design, payment gateway integrations (Stripe, etc.), and cloud deployment. Tech Stack:
Frontend: React, Next.js, TypeScript, Tailwind CSS, React Native / Flutter
Backend: Node.js, Express, Python / FastAPI
Databases & Cloud: PostgreSQL, MongoDB, Supabase, Firebase, AWS / Vercel Why work with me?
End-to-End Ownership: I handle both sides of the architecture—you don't need to coordinate between multiple developers.
Clean, Maintainable Code: No rushed, messy templates. Scalable code built with best practices.
Clear Communication: Regular progress updates, transparent timelines, and active collaboration so there are never any surprise reveals. Let's Talk: Got an idea or a project in mind? Shoot me a DM with a brief description of what you're building, your timeline, and your budget expectations. Let's chat about how we can make it happen! (Portfolio/GitHub available upon request—feel free to drop a comment or DM me for links.)

A music platform for independent Indonesian artists. An artist uploads a release, it goes live on the platform, and listeners find it through artist pages and the catalogue. Payments run through Duitku, and the whole thing runs on the edge, so catalogue pages stay fast without a server to babysit.
What I built
Artist and listener accounts, with an upload flow that takes a release from draft to published.
Artist pages and a browsable catalogue, built for slow connections first.
Payments through Duitku.
A Hono API over D1 on Cloudflare Workers, with a Next.js front end on the same edge runtime.

It is early and I am building it in the open, so the parts that exist are the ones people actually asked for.
Megaverse is a fitness club in Palembang, built as one platform instead of four disconnected tools.
The public site sells the club: programs with intensity and duration, the padel club with court pricing and availability, and the club's postings. The member area is where members live day to day — registration with KTP and address, then profile, class booking, attendance and renewal history.
The front desk side covers renewals and payments, gate logs, and lockers with their rentals.
Behind that sits the business: a POS with products, suppliers, units and categories, employee and personal trainer records with specialisations, and finance with chart of accounts, journals, fiscal periods and fixed assets, with the heavy tables exported to Excel.
Laravel with Blade, Tailwind and MySQL.
Built together with Tengku Kevin Juldianto (dev.tengkukevin@gmail.com).
Finally posting the results of a quick turn-around 0-1 project for a successful electrical commercial contractor, looking to expand into the residential market. The clients were respectful, and trusted me to get them live quickly, while ensuring the site was AEO ready.
As a designer, there are projects that showcase beauty and those that showcase functionality. I feel like we hit the beats to make it personal, functional and am looking forward to add more features and pages to showcase all the work they are capable of.
