The first call is free. I usually reply within 2 hours.

Orders arrive by email, statuses live in a spreadsheet, and clients call to ask what's going on? I design and build a web app around how your business actually works. I lead the project from the first call to launch and I'm your single point of contact.

  • Scope, price and date for each phase in writing
  • A working version after every phase, not only at the end
  • You own the code, the data and the accounts

What costs time today

I start from how people work, not from a feature list.

  • UrgentOrders arrive by email and get retyped into the system

    Wrong quantities and hours of the sales team's day.

    In the app: Clients place orders themselves in a portal with their own price list.

  • UrgentClients call to ask about order status

    Calls pull salespeople away from selling.

    In the app: Status, invoices and order history visible after login.

  • To improveThe weekly sales report is put together by hand

    The numbers are stale before anyone reads them.

    In the app: A dashboard that updates itself.

Phases and prices

Each phase has its own price and date. You can stop after any of them.

2. ERP integrationOrders and invoices flow without retypingIndividual quote
3. DashboardSales and overdue orders visible liveIndividual quote

What could change price or date

Better said before the start than halfway through.

  • To agreeThe ERP has no documented API

    The integration may take longer than planned.

    In the app: A short check of ERP access before phase 2 is priced.

  • To agreeClient price lists are spread over several files

    Moving the data means cleaning it up first.

    In the app: One file template and an import that flags errors.

What you own

Everything is in your name from day one.

  1. The code, in a repository on your account.
  2. The database and hosting, on your accounts.
  3. Documentation: how the app works and how to run it.
  4. Admin access to every service.

Packages

You get the exact price and date for each phase in writing after our call, before you decide.

Selected work

What clients say

  • „We worked with Vlad on a Next.js project. He knew what he was doing from day one, didn't overcomplicate things and came up with better approaches on his own. I especially value his work on the site's performance. Everything was delivered as agreed.”

    George B. CEO, finance company

  • „We needed to build an MVP fast to test our idea in practice. Vlad helped us choose sensible solutions and focus on what we really needed for launch. We didn't try to build everything at once, yet he made sure the project could grow later without starting from scratch.”

    Alex N. Product Manager at StartupX

  • „Vlad got up to speed with our project quickly and pointed out several problems we hadn't treated as priorities. He sorted out our database and security issues. I liked that he didn't just complete tasks but clearly explained why something was worth changing and what the consequences could be.”

    Michał R. CTO at TechCorp

  • „We had an app where every bigger change was becoming a problem. Vlad helped us clean up the code, rebuild some of the older parts and introduce automated tests. Working on new features is much easier now. I also appreciate his patience in explaining technical topics to people outside the development team.”

    Sara K. Product Owner at WebSolutions

Frequently asked questions

How much does a web app cost?

A simple client portal with login and a few views sits near the lower end. A B2B platform with many roles, an ERP integration and payments sits at the top of the range or above it, because each role and each integration is its own piece of work. Regulated systems that need a large team are a different budget level, covered in the cost guide.

How long does web app development take?

Usually from 6 weeks, split into phases. I plan the first phase so people can use it as soon as possible. Every phase has its date in the quote. Integrations with old systems and messy data cause most delays, so I check both before pricing.

Custom web app or off-the-shelf software?

If off-the-shelf software does what you need, use it: it will cost less. A custom app makes sense when the way you work is your edge, when you pay for several tools that don't talk to each other, or when workarounds cost your team hours every week. On the first call I'll tell you honestly which fits.

How is this different from an MVP or a SaaS?

An MVP is a small first version to test an idea. A SaaS is a product you sell to many companies on subscription. This page is about an app for your own business and your clients: a portal, a panel, an internal tool. Each topic has its own page, linked below.

Agency, freelancer or one senior lead?

An agency gives you a big team and several layers of management you pay for. A freelancer can be cheaper, but you carry the risk if they disappear. With me you get one senior person who leads the project end to end and answers for it, with a small team of experts for complex parts. If I'm ever unavailable, the code in your repository and the documentation let a specialist step in or another team take over. It's usually faster and better value than an agency, but I'm not the cheapest option on a freelance marketplace.

Which technology do you build web apps with?

Most often Next.js and TypeScript, or Laravel, with a PostgreSQL database. I pick the stack for the project and for whoever will develop the app later. I explain the choice in plain words before you decide. I work remotely, with calls at times that suit both sides.

Do you guarantee the app will pay off?

No. The return also depends on how your team adopts it. In writing you get what depends on me: the scope, price and date of every phase. That's why we start with the phase that saves time soonest, and you decide after it whether to continue.

Who owns the code, and what happens after launch?

You do. The code, database, hosting and accounts are in your name from day one, with documentation. After launch you can take ongoing support and development, or hand the app to another team. There's no lock-in contract.

I usually reply within 2 hours.
