Open to work and collaboration
Jakarta, Indonesia
I'm Daffa, based in Jakarta. At Kredivo Group I rebuilt a collections platform that now serves four countries and responds more than 75% faster. Outside work I build AI products with Claude and mentor bootcamp students.
Open to collaborations, freelance work and full time roles, in Indonesia and abroad. Remote, hybrid or on site all work for me.
I'm a Full Stack Software Engineer with 4.5+ years across fintech, travel and AI. I move between frontend performance, Golang services and event driven systems, and I built a Claude powered trading extension that is on the Chrome Web Store.
I have led teams of 3 and mentored 200+ bootcamp students, so I care as much about clear specs, reviews and teaching as I do about code.

Rebuilt the hotel and homes accommodation pages in Next.js and TypeScript for one of Indonesia's largest online travel marketplaces, with Lighthouse SEO above 90, LCP under 2.5 s and CLS under 0.1. Also delivered the post purchase flows (Reschedule, Refund, Revise Booking, Self Service Rebook and Relocation) and later moved them to server side rendering, cutting page load from about 8 s to 2 to 4 s.
Architected and shipped pergiceria.com in Golang, Next.js and MySQL, a booking platform for local and international tours with B2C self service and B2B manual orders. Xendit covers 8+ payment channels, Resend and Twilio send notifications, and Mekari Qontak powers CRM and AI for WhatsApp conversations. 20+ transactions worth over IDR 50 million (about USD 2,700) since the August 2026 launch, with 90+ Lighthouse and PageSpeed scores.
Built and launched the website for Pempek Takuw, my own Pre Order food business for authentic Pempek Palembang that opened on 10 November 2026. It is a simple static site in Indonesian and English with a product catalogue, clear pricing, ordering terms, bonus cuko tiers by order size and real packaging photos. Orders are handled manually through WhatsApp, so customers go from browsing the menu to chatting with the seller in one tap, with no backend to maintain.

Architected a Chrome extension AI assistant for real time stock and Web3 chart analysis, published on the Chrome Web Store. Claude's API is the core feature, turning chart screenshots and questions into trend analysis, with a designed system prompt and context enrichment. Owned Google Auth, Stripe payments and PostHog analytics for the full onboarding to payment journey, and led a 3 person team.
Engineered a white label game voucher marketplace engine now powering 4 live storefronts, integrating third-party provider catalogs across 20+ active games from landing and SEO pages to a streamlined buy flow where users pick a game, choose a voucher amount, and pay through our in house payment gateway. Built a dashboard with daily reporting and transaction history, RBAC, and a dynamic CMS for content teams, while sustaining 90%+ unit test coverage (frontend and backend), 90+ green PageSpeed scores on mobile & desktop, and full observability across logs, latency, and server health.
Built an interactive 3D workspace designer where people rent desks, chairs, monitors and accessories by the week instead of buying them. Instead of a normal product grid, users place catalogue items in a real 3D room, move and rotate them, and watch the weekly price, bundle discount and total update live, with weekly or monthly billing and USD or IDR. An Ask AI assistant turns a plain description such as "I am a CEO of a software house" into a suggested setup with an estimated cost that can be added to the room in one click, with quick start presets for Freelance Developer, Day Trader and Content Creator. Setups can be saved, shared by link and sent by email with the estimate. Responsive from desktop to mobile, with light and dark themes.
