Registration, profile, requests, history, documents, messages, statuses and personal data.

WEB APP / PRODUCT ENGINEERING
Custom web application development
I design and build web applications with authentication, roles, data, dashboards, APIs, files, notifications and real business logic — from the first core flow to production.

Beyond a website
Users return to work, not just read
A web app is the right model when users have state, data, roles and recurring operations that must survive beyond a single session.
Internal system
Teams work with orders, entities, queues, rules and reporting inside the browser.
Online product
Users receive direct utility through calculation, management, data processing, subscription or automation.
Technical scope
Frontend and backend as one system
A strong web application starts with data, roles and critical operations rather than screen count.
01
Authentication and roles
Registration, login, recovery, RBAC, permissions and server-side authorization.
02
Data and CRUD
Models, relations, migrations, search, filters, states and transactional operations.
03
Dashboard and UI
Operational screens, loading/empty/error states, responsive layouts and information density.
04
APIs and integrations
REST APIs, webhooks, payments, CRM, Telegram, external services and background jobs.
05
Files and notifications
Private storage, upload/download, email/Telegram and event-driven flows.
06
Production
Tests, env, HTTPS, server, logs, backups and controlled releases.
Process
Domain model and critical flows first
Define roles, entities and the first end-to-end value flow.
Design data, APIs, permissions and frontend/backend boundaries.
Build working vertical slices rather than empty screens.
Failures, races, permissions, mobile, performance, deployment and backups.
Real mechanics
The cases show more than interface
Danaflex and DROPIX represent two very different web products: an operational system and an interactive platform.
Trust / How I work
Less uncertainty.
More control.
The stressful part of software is rarely just the price. It is not knowing what is happening, who owns the outcome, or what remains under your control after launch. I design the process to make those things visible from the start.
01
You always know what is happening
The project has clear stages, a current state and a next action. No vague “almost done” status and no technical fog.
02
Source code and access stay with you
The codebase, structure and key credentials do not become leverage. The product can be continued without artificial vendor lock-in.
03
You talk directly to the developer
No manager translating between the problem and the implementation. Context stays intact and decisions can be discussed directly.
04
Risk before code
Before active development, I review scope, integrations, data, critical flows and launch constraints. That is cheaper than repairing the architecture after release.

FAQ / Web app
Common questions before development
01How is a web app different from a website?+
A website is primarily consumed. In a web app, users authenticate, manipulate their own data, perform operations and return to persisted state.
02How much does a web application cost?+
Budget follows roles, entities, critical operations, integrations and reliability requirements. The useful first step is defining the first complete vertical flow.
03Can we start with an MVP?+
Yes. One end-to-end flow with a real database and backend is usually more valuable than twenty disconnected screens.
04Do I keep the code and database?+
Yes. Repository, infrastructure access and data should stay under client control without vendor lock-in.

Describe one primary user flow
Who enters the system, what they do and what result they need. That is enough to start mapping roles, data and architecture.
