Zuanda B.

I build fast, modern websites and web apps for founders and product teams, and I stay around to grow them. Eight years in production with React, Next.js, Astro and SvelteKit on the front, Node.js, NestJS and PostgreSQL behind it. Top Rated Plus, 100% Job Success Score, working with clients in Australia, Switzerland, the US and Indonesia. WHAT CLIENTS HIRE ME FOR • Turning Figma designs into clean, responsive, accessible React or Astro frontends • Headless CMS builds (Payload, Sanity, Strapi) so your team can publish without a developer • Stripe checkout and subscriptions, third-party APIs and webhooks, AI assistants and RAG features • Speeding up or untangling an existing Next.js or Astro codebase • Full-stack features when the project needs them: data model, API, database and deployment on Vercel or a VPS RECENT WORK • Cool (Australia) — curriculum-aligned education platform with ~220,000 teacher accounts. Migrated the existing Laravel app to full-stack Next.js and still ship new features. Built CoolPlus, its AI lesson builder, with Clerk sign-in and Stripe subscriptions. • Diavaia — global storefront for 1.3M+ certified natural and lab-grown diamonds. Led a two-person team: shape-first faceted search, supplier inventory feeds, multilingual and multi-currency checkout, Payload CMS. • Soludoo (Switzerland) — multilingual Astro + Sanity sites (EN/DE/FR/IT) for an Odoo consultancy and its sister companies, plus a headless e-commerce starter kit the agency now reuses. • TALD (US), Higher (Indonesia), Dzyns, Erai Tech — two marketplaces, a design-subscription site with its client dashboard, and a SaaS company site with live product previews. • Madrasah Imam An-Nawawi — full-stack Next.js site for a four-school foundation, with PostgreSQL set up on a VPS including backups. Each of these has a case study with screenshots in my Portfolio section below.

If a design or spec doesn't add up, I say so before building, not after. I agree the API contract and scope up front, send a short progress note at the end of each working day, and write the handover docs myself so your next developer is not stuck. I'm in Banda Aceh (UTC+7): my mornings overlap Sydney and my afternoons overlap Zürich, so a same-day reply is normal. Comfortable working async in English. Available for fixed-scope projects and long-term hourly contracts. Send me the brief or the Figma file and I'll come back with a scoped estimate within one business day.
