Product Engineering

Web applications engineered for performance, security and scale.

Appmetry builds SaaS products, customer and partner portals, marketplaces, dashboards and internal business tools, with modern stacks and the architecture discipline that comes from scaling a marketplace to 80M+ users.

  • SaaS platforms, portals, marketplaces and internal tools
  • React, Next.js, Node.js, Python and cloud-native backends
  • Fast, accessible, SEO-friendly front ends
  • Integrations with ERP, CRM, payments and AI

Web development services

  • SaaS product development: multi-tenant architecture, subscriptions and billing, roles and permissions, usage analytics.
  • Customer, dealer and vendor portals: orders, invoices, service requests and self-service, connected to your ERP.
  • Marketplaces and commerce: catalogues, search, payments, logistics and seller tools.
  • Dashboards and internal tools: replace spreadsheets with secure, role-based apps.
  • Progressive web apps: installable, offline-capable apps, like our Dispatch Challan Flow for distributors.
  • Modernisation: move legacy PHP, .NET or monolithic systems to maintainable modern stacks.

Engineering standards

  • Type-safe code, automated tests and code review on every change
  • CI/CD pipelines with preview environments
  • Security by default: OWASP practices, secrets management, audit logs
  • Observability: logs, metrics, tracing and alerting
  • Performance budgets and Core Web Vitals monitoring

Architecture that scales

Our founders' experience scaling Poshmark, from a small startup to a global marketplace with 80M+ users and $1.8B+ GMV, shapes how we design systems: clear service boundaries, caching and queueing where they matter, and databases designed for growth.

How we work

  1. Discovery and scoping with a clickable prototype
  2. Architecture and technical plan
  3. Two-week sprints with demos
  4. Launch with monitoring and a support plan
  5. Ongoing product development as a long-term partner

Web Application Development: frequently asked questions

What kinds of web applications do you build?

SaaS products, B2B and B2C portals, marketplaces, booking and ordering systems, analytics dashboards, admin panels and internal workflow tools, as well as progressive web apps (PWAs) that work on mobile without an app store.

Which technologies do you use?

Typical stacks are React or Next.js with TypeScript on the front end, Node.js or Python (FastAPI, Django) on the back end, PostgreSQL, Redis and cloud services on AWS or Google Cloud. We choose based on your team, scale and integration needs.

Can you build a SaaS MVP?

Yes. A SaaS MVP with authentication, multi-tenant data, billing and a core workflow typically takes 8 to 14 weeks. We design the architecture so it can grow without a rewrite.

Do you make web apps SEO and AI-search friendly?

For public pages we use server rendering or static generation, structured data, clean URLs, fast Core Web Vitals and llms.txt so search engines and AI assistants can understand the content.
