A tailored scope, not a boxed package

A landing page, a webshop and an operational system need different decisions. Your proposal reflects the work your project actually needs.

Part of every engagement

  • Mobile-first implementation
  • Clear scope, milestones and cost before development
  • Early previews and practical feedback rounds
  • Launch support and a handover you can use
  • An invoice and a written agreement
  • Source-code ownership after full payment, unless agreed otherwise

What determines the quote

Goals, required features, content volume, integrations, platforms and delivery timing. A short conversation is enough to define the next useful step.

Quotes are issued net. Ongoing maintenance and new development can be scoped separately after launch.

A process with no mystery phase

You see what is happening, what comes next and what each decision changes.

  1. Define the useful outcome

    We discuss the audience, business goal, existing systems, must-have features and what success should look like.

  2. Approve a clear plan

    You receive the proposed scope, delivery approach, timing and price before development begins.

  3. Review real progress early

    I share working previews, explain tradeoffs and keep feedback attached to decisions rather than surprises.

  4. Launch with a next-step plan

    I handle production release, store or domain setup, analytics and handover. Continued support stays available.

Gergő Szabó, developer and founder of szbdev

Senior attention without the agency relay

I am Gergő Szabó, a developer and independent product builder in Hungary. I started learning to code at twelve and have worked professionally across web and mobile products for ten years.

Since 2021 I have worked at BarSoft on hospitality software including iPanel, BrandApp and KIOSK. Alongside that work, I build my own products and websites for independent businesses.

When we work together, the person in the first conversation is also the person making the technical decisions and writing the code.

  • Direct communication
  • Web and mobile delivery
  • Hungarian and English
  • Long-term product support

Questions before we start

Straight answers about scope, ownership, visibility and what happens after launch.

Do you only build fully custom websites?
No. I recommend the approach that fits the business. A custom Next.js site is right when performance, content and brand need precise control. For commerce, Shopify, Shoprenter or WooCommerce can be the more responsible choice.
Will the result work properly on mobile?
Yes. Mobile behavior is part of the core implementation, not a paid extra. I test responsive layouts, interaction states and critical journeys across phone, tablet and desktop sizes.
Can you help with SEO?
Yes. I can audit and implement technical foundations including indexing, metadata, structured data, sitemaps, internal structure, performance and Search Console measurement. Rankings cannot be guaranteed, but the technical work will be clear and measurable.
Do you have a fixed price list?
No. A useful quote depends on the required features, content, integrations and timing. After a short discovery conversation, you receive a written scope and price before work begins.
How long does a project take?
It depends on complexity and how ready the content and decisions are. The expected schedule is defined in the proposal, with working previews shared before the final release.
Who owns the source code?
After full payment, source-code ownership transfers to you unless our written agreement defines a different arrangement. Third-party services and licensed packages remain subject to their own terms.
Can you maintain an existing product?
Yes. I can take on audits, fixes, new features, analytics, store updates and ongoing development when the current stack and codebase are a responsible fit.
Do you issue invoices?
Yes. Every engagement is invoiced, and quotations are stated as net amounts.
