Issue reproduction
Environment, trigger and expected behavior recorded.
Find why a function fails, slows down or behaves unpredictably. We review the relevant code and produce prioritized findings with reproduction steps and a realistic repair scope.

We define the scope and prepare the agreed first prototype or work plan before payment.
You approve the prototype and pay 30%. We begin the agreed implementation.
We show the main pages and functions or agreed milestone deliverables. After acceptance, you pay the next 30%.
We finish the agreed checks and hand over the project, materials and access. You pay the remaining 40% after acceptance.
Scope agreed before work begins. All prices in USD. Applicable taxes and third-party fees are confirmed in the proposal.
We agree the scope and prepare the first prototype before the first payment. You can review the proposed structure and customer journey before deciding to proceed.
The agreed initial prototype covers the key page or customer journey. For SEO, advertising and other projects without an interface, the first reviewable result is a proposed work plan. The number of screens and revisions is agreed in the brief.
You approve the prototype or work plan and pay 30% of the agreed project price. We then begin implementation.
We demonstrate the agreed main pages and functions, or the named project deliverables. Once you accept this milestone, the next 30% is due.
We complete the agreed checks, deliver the project and hand over the agreed materials and access. The remaining 40% is paid after acceptance.
This schedule applies to projects with a fixed scope. Monthly work and small hourly tasks have separately agreed terms. Advertising spend, hosting, licences and third-party fees are listed separately in the proposal.
We deliver remotely. Briefing, reviews and handover take place online, with the meeting times and working language agreed in advance.
Scope, selection criteria and practical delivery details.
An error message, slow request or incorrect total provides a better starting point than a general request to improve everything.
We agree the relevant component and available access before reviewing the code.
Each actionable finding should identify the condition, affected behavior and evidence. Unconfirmed concerns are labeled for further investigation.
A focused review is not an exhaustive security certification. Wider performance or security testing needs its own scope.
Fixes are proposed in priority order. We check the original failure and important neighbouring cases in a staging environment.
Vladimir Nikolaev reviews remaining risks and dependencies with you. Unsupported third-party components may require replacement rather than a patch.

CEO and web development & SEO expert. Web developer and SEO specialist since 2015. Vladimir Nikolaev reviews data rules, implementation choices and acceptance checks with you, so the technical work follows a defined business task.
Answered by Vladimir Nikolaev.
Yes, with lawful access to the code and a defined review question.
Only agreed repairs. Larger changes receive a separate scope.
No. Review coverage and unresolved findings are documented.
Yes. A staging copy is preferred for reproducing failures and checking repairs.

Give your team one place to manage requests, records and approvals. We build browser applications around the work people actually do, with clear access rights and a practical first release.

Add the function your website is missing without rebuilding the whole system. We develop extensions with a defined job, manageable settings and checks against your current platform.

Help buyers estimate a service or configure a product before they contact you. We turn your pricing rules into a clear calculation, with useful explanations and a route to a qualified inquiry.
Include a safe example, logs and platform details. We will define a focused review.
