Custom Software Development for Systems You Cannot Buy

Custom software development for the systems nobody sells off the shelf

When the product you need does not exist, buying the closest thing and bending your business around it is usually the more expensive option. Bespoke software development is what we do instead.

  • Web and mobile product build
  • Legacy system replacement
  • API and integration layers
  • Design systems and UX

Custom Software

Custom software development at TekRouting means a small senior team, two-week increments, and something usable in your hands inside the first month. Your engineers are in the repository from the first commit, not handed a zip file at the end.

Custom Software

Custom Software at TekRouting

We replace legacy systems by strangling them: new capability alongside the old, traffic moved slice by slice, and a rollback that works at every step. The software is also the carrier for everything else we route in — the AI models, the ledger, the data platform all reach your users through it.

Front end:

  • TypeScript
  • React
  • Next.js
  • Swift / Kotlin

Web & mobile product build

End-to-end delivery from discovery through launch, including design system, accessibility and performance budgets.

Legacy replacement

Incremental migration behind a facade, so the old system keeps running until the day nobody needs it.

Back end:

  • Node.js
  • Go
  • Python
  • PostgreSQL

API & integration layers

Contracts, versioning and the unglamorous adapters that make ten systems behave like one.

Design systems & UX

Component libraries and research practice your team can extend without calling a designer for every screen.
