Software
Development

SaaS platforms, APIs and dashboards engineered for performance, scale, and long-term maintainability. Two senior engineers. No agencies. No middlemen. Direct.

── WHAT WE BUILD ─────────────────────────────────────────

We build the software behind startups: the SaaS product itself, the API that powers it, and the internal dashboards founders use to run it. Everything is written in TypeScript end to end — Next.js on the front, Node.js and NestJS on the back, PostgreSQL underneath — so one small team can own the whole stack without hand-offs.

Recent work includes an operations dashboard with role-based access and real-time analytics, a payments and auth API with automated monitoring and OpenAPI docs for partners, and a Telegram bot that pushes live market alerts to traders. You can read the problem, solution and result for each in our case studies.

── FAQ ───────────────────────────────────────────────────

Q: How fast can you ship a Web2 MVP?

A: Timelines depend on scope. We prioritize fast iterations and outline an MVP plan after a short discovery call, then ship working software in short milestones.

Q: What types of products do you build?

A: SaaS platforms, admin dashboards, REST and GraphQL APIs, marketing sites, and performance-optimized web applications.

Q: Do you handle design as well?

A: Yes. We cover UI/UX design, component systems, and responsive layout — not just backend.

Q: Which tech stack do you use?

A: Next.js and React with TypeScript on the front-end; Node.js or NestJS APIs with PostgreSQL and Redis on the back-end; AWS or Vercel for hosting; Stripe for billing. We will work inside an existing stack when that is the better call.

Q: Do you offer maintenance after launch?

A: Yes. We offer ongoing maintenance, monitoring, and feature work on a monthly basis, or a clean handover with documentation if your team takes over.
