Ehsan Bayranvand

I am a senior full-stack web developer with 6+ years of experience building and shipping production SaaS products for international teams. I specialize in React, Next.js, and TypeScript on the frontend and Node.js APIs on the backend, with strong focus on performance, reliability, security-minded integrations, and maintainable architecture.

What I can build for you

Business websites, landing pages, and marketing sites (fast, responsive, SEO-friendly)
Custom web applications and admin dashboards
Multi-tenant SaaS features: authentication flows, user accounts, billing hooks, operational tools
API design and integration (REST, third-party services, payment providers such as Stripe)
Refactoring and performance work on existing React/Next.js codebases (smaller bundles, better UX, fewer production errors)
How I work

I support clients from requirements and technical planning through delivery and launch: clear milestones, regular communication, code you can maintain, and observability so issues are caught early. I am used to remote collaboration across time zones (based in Yerevan, Armenia, UTC+4) and comfortable working in English with product owners, designers, and other engineers.

Background
I have delivered full-stack work at product companies including multi-tenant SaaS (billing and webhook pipelines, React/Node.js, PostgreSQL/MySQL) and large-scale Next.js platforms with complex user journeys, CI/CD, and production monitoring (Sentry). I have also architected greenfield applications from scratch—from UI and APIs to deployment—so I can help whether you need a new MVP or to strengthen an existing product.
If you need a dependable developer who combines strong frontend craft with solid backend execution and cares about correct data and stable releases, I would be glad to discuss your project and propose a clear plan and timeline.
