Philosophy-trained. Engineering-obsessed. I build front-end experiences where users meet emerging tech, from Web3 payment rails to AI agent dashboards.

My background is not a typical engineering path. I earned a B.S. in Philosophy from University of Indonesia, learning to question assumptions, map systems, and argue with clarity. Now I am pursuing an M.S. in Information Systems at Telkom University while shipping production code at SLTR Group.
That interdisciplinary lens shapes how I build. I do not just write components. I design the space where complex technology becomes intuitive for real people. Whether it is a Web3 wallet connection, an AI agent training interface, or a payment gateway onboarding flow, every screen is an argument. And I aim for clarity.
Core stack
Next.js, TypeScript, Tailwind CSS. Deep experience in blockchain integration (Wagmi, Viem, EVM chains), AI microservices, and payment systems.

Relynk
Most creators lose a cut of every dollar to platforms. Relynk asks: what if they owned the entire stack? I built the front end for a creator-first payment layer on LISK, Scroll, and Morph, abstracting wallet connections, on-ramping, and IPFS content hosting into something that feels like a familiar checkout. The goal was not to impress crypto-natives. It was to make a first-time user feel safe sending their first stablecoin.
- Integrated with LISK, Scroll, and Morph (currently in testnet).
AI agents are powerful, but the interfaces to build them are usually built for engineers. Chatto is a dashboard where non-technical users can create, train, and deploy agents without touching a config file. I designed the interface around a mental model people already understand: chat. Then I layered in training pipelines, payment integration, and microservice orchestration underneath. The hard part was making complexity feel like conversation.
- Integrate with payment and AI agent microservices.
Payment gateways live or die by how fast a partner can go from signup to first transaction. The old HORUS onboarding was a chain of emails and PDFs. I rebuilt it as a self-serve dashboard where partners complete KYC, configure API keys, and monitor settlements in one place. Every screen was designed around one question: what does this partner need to see right now to feel confident?
- Seamless, secure, intuitive UI for partner to onboard and get used.
Small merchants in Indonesia sell digital goods (phone credit, game vouchers, data packages), but most lack the infrastructure to do it at scale. INSTN.ID is a multi-tenant platform where each merchant gets their own branded storefront, inventory, and pricing layer, all feeding into the HORUS payment rail. I built the front end to feel like a single-tenant app even though every route, theme, and transaction flow is dynamically scoped.
- Integrate with company payment gateway HORUS for seamless transaction.
Editorial teams should write, not wrestle with CMS buttons. Gamefinity is a gaming media platform where editors publish in WordPress and readers experience a fast, modern front end built in Next.js. The architecture challenge was keeping editorial workflows untouched while delivering sub-second page loads and a reading experience that feels native, not templated.
- Integrate with WordPress as a headless CMS to write and store content then consumed by the front end.
