Custom web platform development

Custom web platforms, built to scale with you

SaaS products, customer portals, and internal platforms with AI features built in, not bolted on.

What it is

Custom web platform development means building web software around your exact workflows, data, and users, rather than adapting an off-the-shelf tool. Typical examples are SaaS products, customer and partner portals, marketplaces, and the admin and operations systems behind mobile apps. Tech Insane builds these with modern TypeScript stacks, secure multi-tenant architecture, and AI features such as search, summarization, and assistants where they improve the product.

Outcomes

What changes for your business

A platform that fits the business

Your workflows, roles, and data model, not a compromise between three tools.

Performance users notice

Fast page loads, responsive interfaces, and Core Web Vitals treated as acceptance criteria.

Ready for enterprise buyers

SSO, role-based access, audit logs, and security practices that survive a procurement review.

What we build

Typical web platforms projects

SaaS products

Multi-tenant products with billing, onboarding, and analytics.

Portals and dashboards

Customer, partner, and operations portals with real-time data.

Admin and back-office systems

The control centers behind mobile apps: dispatch, content, support, and reporting.

Large-scale platforms

High-traffic, public-sector-grade platforms with AI assistants and accessibility built in.

Approach

How we deliver it

This sits inside our standard delivery process: weekly demos, a shared board, and monthly reporting.

Technology

  • TypeScript
  • Next.js / React
  • Node.js
  • Python
  • PostgreSQL
  • Redis
  • AWS / GCP / Cloudflare
  • Docker & Terraform
  1. Architecture and data model agreed and documented before build.

  2. Design system first, then features, so the UI stays consistent as it grows.

  3. CI/CD, preview environments, and automated tests from the first sprint.

  4. Security review and load testing before launch.

  5. Observability and on-call runbooks handed over at go-live.

Two ways to engage

Web platforms: frequently asked questions

Do you build the admin panel behind our mobile app?

Yes. Most of our mobile work includes the operations side too: dispatch, content management, support tools, and reporting.

Can you add AI features to an existing web platform?

Yes. We typically start with one high-value feature, such as semantic search, document summarization, or a support assistant, and integrate it with your current stack.

How do you handle security?

Least-privilege access, secrets management, dependency scanning, encrypted data at rest and in transit, and a pre-launch security review. See our security practices on the How We Work page.
