Product definition and domain model
Users, roles, permissions, entities, states, edge cases, integrations, and success criteria are mapped before expensive implementation choices are locked in.
Custom software & SaaS
Software shaped around the real workflow, not a generic feature checklist.
Yander designs and develops web applications, SaaS products, dashboards, marketplaces, and internal platforms. We connect interface decisions with permissions, data models, business rules, payments, integrations, and the operational tools needed after launch.
The product is defined as a working system: who uses it, what states exist, what information moves between people, which decisions must be controlled, and how the team will operate it every day.
Best fit
- A founder turning a validated workflow into an MVP or commercial SaaS product
- A company replacing spreadsheets, chat, or legacy tools with one operational system
- A marketplace that needs identity, transactions, payouts, and admin controls
- An AI-enabled product that needs usable workflows around model capabilities
What we deliver
UX/UI and prototype
Critical workflows are designed and tested through interface states, responsive behavior, empty and error cases, and a reusable product design system.
Frontend, backend, and integrations
Implementation can cover application UI, APIs, database logic, authentication, payments, notifications, storage, AI providers, and agreed third-party systems.
Operations, QA, and handoff
Admin tools, auditability, deployment, monitoring readiness, role-based access, testing, documentation, and repository ownership are treated as part of the product.
How we approach it
- 01Model the workflow, roles, business rules, and risky edge cases before estimating screens.
- 02Prioritize a coherent first release that proves the core transaction or operational loop.
- 03Design UI and architecture together so product promises match technical behavior.
- 04Ship with deployment access, documentation, and a clear path for iteration or internal handoff.
Typical capabilities
- Next.js, React, and TypeScript web applications
- API, database, authentication, and role-based access
- Payments, subscriptions, marketplace payouts, and credits
- AI, storage, email, and third-party integrations
- Admin operations, testing, deployment, and monitoring readiness

Service FAQ
Can Yander start with an existing specification or codebase?
Yes. We first review the product model, existing decisions, code quality, deployment, and known constraints, then define what should be preserved, repaired, or rebuilt.
Do you build both the customer product and admin tools?
Yes when both are required. Operational workflows, moderation, support, content, permissions, and reporting often determine whether the customer-facing product can run reliably.
Can payments, subscriptions, or marketplace payouts be included?
Yes. The exact provider and flow depend on business model, countries, compliance requirements, refunds, taxes, connected accounts, and ownership of funds.
How long does custom software take?
A focused custom platform usually starts around 8–12 weeks. Scope, integrations, data migration, regulatory requirements, and approval speed are the main variables.
