Custom Software Development
Tailored web platforms, internal business tools and complex SaaS systems — engineered to scale with your operation, not against it.
Off-the-shelf software fits 70% of the problem. The remaining 30% — the part that gives your team competitive edge — needs to be built. T-Square engineers production-grade applications in TypeScript, Node.js, Laravel and PostgreSQL, with senior developers owning each engagement end-to-end.

Frequently asked questions.
Quick answers about how we engineer, deliver and operate custom software development.
01What types of custom software does T-Square build?
B2B SaaS platforms, internal admin tools, customer portals, multi-tenant business systems, marketplaces and bespoke workflow software. Each product is engineered from scratch in TypeScript, Node.js, Laravel and PostgreSQL — typically delivered in two-week sprints with weekly demos.
02How long does a typical custom software project take?
A standard MVP runs 12–16 weeks from kickoff to first production release. Discovery is 1–2 weeks; design and architecture 2–4 weeks; build is 8–10 weeks of two-week sprints. Larger multi-module platforms scale to 6–9 months with phased rollouts.
03Do you provide ongoing maintenance after launch?
Yes. Every engagement can include hosting on AWS or Hetzner, observability with Sentry and Grafana, CI/CD via GitHub Actions, security hardening and a real on-call rotation. Many clients use T-Square as their full in-house technology team.
04How do you protect data and intellectual property?
All engagements run under signed NDAs and KVKK / GDPR-aligned data-processing addenda. Source code is delivered to your repository; secrets stay in your vault; production data never leaves EU-region servers without explicit consent.
