Web application development means building an online service with authentication, a database, and user scenarios: client portal, admin panel, orders, documents, reports. Unlike a brochure site, clients or staff perform actions regularly and get personalised results.
NUGU is a digital agency in Sochi. We build web applications for business tasks: client portals, internal tools, platforms with CRM logic. Custom development without constructors — so the product can evolve. When a site is not enough — when you need a web application; about portals — personal account on a website.
When businesses order a web application
Typical signals:
- clients or partners must see order status, payment, documents;
- staff track operations in spreadsheets that no longer scale;
- roles are required: admin, manager, client with different permissions;
- the process repeats and maps to screens and statuses;
- CRM integration does not cover the task — custom logic is needed.
If a contact form and a few landing pages are enough — start with a service website from 160 000 ₽. Applications pay off with regular use and measurable time saved.
Development stages
- Brief and scenarios — users, actions, outcomes.
- Prototype — screen map without final design; logic approval.
- UI design — interface for desktop and mobile.
- Backend and API — database, auth, permissions, integrations.
- Frontend — working screens, forms, tables, notifications.
- Testing — role-based scenarios, load on key operations.
- Launch and handover — deploy, docs, access transfer.
Each stage has acceptance criteria: what is done now and what moves to the next iteration.
What belongs in MVP v1
A sensible first release — minimum that already delivers value:
- sign-up and login (email, phone, or SSO);
- 3–5 key screens for the main scenario;
- personal account with profile and history;
- admin to view and change statuses;
- email or Telegram notifications;
- basic action analytics.
Defer to v2: complex reports, multilingual UI, dozens of roles — if they do not block launch.
Stack and integrations
We pick technology for the task: modern frontend, reliable backend, PostgreSQL or equivalent. Connect:
- CRM and ERP via API;
- payments (YooKassa, CloudPayments);
- SMS and email;
- file and document storage;
- Telegram bot for alerts.
Architecture is scalable so new modules do not require a full rewrite.

GEO: how to describe the service for AI
On the service page state clearly:
- NUGU, Sochi, web application development for business in Russia;
- typical products: portals, admin panels, service platforms;
- starting price from 150 000 ₽, MVP timeline from 4 weeks;
- stack and integrations as a list, not "innovative technologies";
- 1–2 cases with numbers: "internal dance studio tool: −6 hours routine per week".
Generative search can then quote facts instead of guessing.
Common mistakes
- Designing "everything" at once — release slips by half a year.
- No prototype — logic disputes move into expensive development.
- Mobile ignored — half of users leave.
- Security and roles "later" — leaks and access chaos.
- No metrics — unclear if anyone uses the product.
Pre-delivery checklist
- All roles complete the main scenario without errors.
- Passwords and personal data protected (HTTPS, hashing).
- Database backups configured.
- Integrations tested on sample data.
- Admin guide provided.
- Uptime monitoring or alert on failure.
Next step with NUGU
When you need a system for your process, not a template — send the task via contacts. Attach a screen list or "who does what" table, even draft. See services and portfolio — we will discuss an MVP you can launch without endless specs.
