Elmar I.

I build production SaaS, payment systems and mobile apps in Next.js, Node.js and TypeScript — and I've been shipping software for 20+ years with a 100% Job Success Score here. What that looks like in practice: — Built eona.ae, a UAE precious-metals investment platform, end to end: backend, customer site and admin console as three Next.js apps in one Turborepo, on Supabase and Vercel, with a live gold/silver/platinum rate feed — Built viplife.az, a bilingual e-commerce ecosystem, end to end: Node.js backend over a legacy MSSQL database, Next.js storefront for 70K users, payment gateway integration, and a React Native app on iOS and Android — Held 200K concurrent users on a news platform running on a modest VPS — Redis caching, Nginx tuning and query optimisation were what made that possible — Shipped an app that passed 200K downloads — Delivered an event ticketing platform that handled 20,000+ registrations and 5,000+ day-of check-ins — Built a multi-tenant restaurant SaaS from scratch: QR ordering, payments, CRM, cashback — Led a team of 4 engineers on a multi-product e-commerce build Stack: TypeScript, Next.js (App Router and Pages), React, React Native (Expo), Node.js, Express, GraphQL, REST, PostgreSQL, MySQL, MSSQL, Prisma, Redis, Supabase, Tailwind, Svelte/SvelteKit, Turborepo, Docker, AWS, Vercel. Stripe and local payment gateway integrations. I take full ownership: requirements, schema design, implementation, deploy, monitoring, and the bugs afterwards. Most of my clients come back. I work on UTC+8 — 4+ hours of daily overlap with US mornings, and full overlap with Europe and APAC. Tell me what you're building and I'll tell you honestly whether I'm the right person for it.
