Service
Web Application Development Services
Hashorn builds production-grade web applications with Next.js, React, and TypeScript. From customer-facing SaaS to internal tools, we ship multi-tenant, observable, and secure web apps with QA and security thinking present from the first sprint.
Why teams hire us
What we solve
The recurring patterns that bring product teams to Hashorn.
MVPs that won't survive their first ten customers.
Front-end performance budgets that drift after launch.
Multi-tenant features bolted on after the data model is set.
Authentication and authorization shipped without threat modelling.
Slow page loads and poor Core Web Vitals on customer-facing pages.
What you get
