Building resilient web systems, decentralized solutions, and digital integrity through clean architecture and permissioned blockchain engineering.

Hello! I am a full-stack developer and computer science student dedicated to engineering dependable, highly scalable digital solutions while actively exploring decentralized trust mechanisms. My technical philosophy bridges software engineering rigor with intuitive user experiences translating complex organizational requirements into high-performance web applications, robust backend microservices, and tamper-proof decentralized systems.

My primary academic research centers on distributed ledger architectures and cryptographic data integrity. For my undergraduate thesis, I designed and implemented an enterprise permissioned blockchain architecture using Hyperledger Besu with a Proof of Authority (PoA) consensus mechanism to validate Surat Keterangan Pendamping Ijazah (SKPI) in higher education. This work focuses on eliminating credential fraud, writing secure Solidity smart contracts, and establishing immutable audit trails suitable for strict institutional governance frameworks.

Beyond blockchain, I engineer across the entire modern software stack. On the backend, I leverage Laravel, Node.js (Express.js), Go, and Python to architect robust RESTful APIs, asynchronous services, and secure communication channels. My data layer strategies span relational engines like PostgreSQL and MySQL, document-based stores like MongoDB, in-memory caching layers with Redis, and cloud-native solutions via Supabase. For the client side, I build responsive, highly optimized interfaces using TypeScript, Next.js, React, Vue.js, and Astro, styled cleanly with Tailwind CSS.

I embrace modern DevOps and cloud workflows, relying on Docker for reproducible environments, Git for collaborative version control, and deploying across AWS and Vercel. With a solid foundation in UI/UX design via Figma, I ensure technical implementations align seamlessly with visual clarity and usability. A security-first mindset underpins everything I write whether conducting vulnerability assessments, refining database schemas, or hardening smart contracts with the ultimate goal of delivering resilient, production-ready software.

Selected work

  • Whisper PayWeb3 / Blockchain

    Whisper Pay is an AI-powered bill splitting and private payment link service built on Starknet. Users photograph a receipt, and Claude reads the items, splits the cost among participants, and generates individual private payment links. Transactions are settled in STRK through the STRK20 privacy pool, keeping amounts, payers, and recipient identities completely off the public ledger without storing uploaded receipt data.

  • Baraqbah Beach Nature Link-in-BioCategory

    A sleek link-in-bio landing page for Baraqbah Beach Nature located at Guci Batu Kapal Beach, South Lampung. It serves as a central hub connecting visitors directly to WhatsApp reservation, social media channels (Instagram & TikTok), Google Maps navigation, and management contact info.

  • Baraqbah Beach Nature - Official Tourism WebsiteWeb Application

    An official tourism showcase website for Baraqbah Beach Nature (Guci Batu Kapal Beach, Kalianda, South Lampung). Built with an elegant, responsive layout, it presents the natural white sand beach, iconic cliff formations, family-friendly recreation, and private camping packages. To maximize visitor conversion and ensure quick customer support, all primary Call-to-Action (CTA) triggers route visitors directly to the management's WhatsApp chat for instant inquiries and reservations.

  • Maja Village Official Profile WebsiteWeb Application

    The official profile web portal for Maja Village, Kalianda, South Lampung. Designed for public information transparency and local tourism promotion, the platform showcases integrated demographic statistics, interactive village mapping, latest news updates, and local highlights like Maja Beach. Built with a clean, modern, and fully responsive layout to provide an accessible digital experience for residents and visitors alike.

  • WebGIS Digital Map of Maja VillageWeb Application

    An interactive, mobile-first WebGIS platform for digital spatial mapping of Maja Village. Built on top of geospatial shapefile data converted into GeoJSON, it accurately renders administrative boundaries (village, sub-villages/dusun, and RT divisions) alongside vital local infrastructure including government offices, places of worship, educational facilities, public amenities, and tourism spots. Features dynamic layer filtering, satellite basemap toggling, responsive mobile bottom-sheets, and photo-enabled location popups.

The full list lives in the project archive.
