Frequently Asked Questions

I usually respond within one calendar day, including Saturdays and Sundays.

First, you briefly describe the task, the current process, and the desired result. I then clarify the details, assess possible implementation options, and suggest the next steps.

Usually, a task description, a sample file or data structure, screenshots, or a brief explanation of the current process is enough. More complex tasks may require additional materials or test data.

That is completely fine. You do not need to decide in advance whether the solution should use Excel, Power BI, Google Sheets, a web application, or another tool. The task is defined first, and the technology is selected afterward.

Yes. I can review the current process, identify manual or repetitive operations, and propose one or more automation options.

No. If automation would be more complex, more expensive, or less convenient than the manual process itself, I will say so. Sometimes it is enough to improve the data structure, a formula, or one specific step in the workflow.

Yes. The solution is configured around the specific process, data structure, business rules, users, and technical constraints.

Yes. It can be an audit, a single formula, macro, script, dashboard, integration, module, or a specific stage of a larger project.

Yes. A larger project can be divided into separate stages, each with its own result, testing, and payment.

Yes. For a complex or new task, it is often useful to build a limited version first, validate the logic in practice, and then expand the solution.

Urgent tasks are possible depending on current workload, complexity, and the required deadline. It is best to mention the urgency at the first contact.

The cost depends on the complexity, scope, and format of the work. A preliminary estimate is prepared after the task is clarified. Current rates and terms are listed on the Pricing page.

The estimate takes into account the scope of work, logic complexity, number of integrations, condition of the source data, testing needs, documentation, and other technical factors.

Yes. The first short discussion of the task and its general context is free of charge. Detailed analysis, solution design, or implementation may be a separate paid service.

The payment format depends on the size and duration of the task. Small jobs can be paid as individual assignments, while larger projects can be paid in stages or according to an agreed scope of work.

It depends on the specific project, its scope, and the cooperation format. Payment terms are agreed before work begins.

First, I assess how the change affects the work already completed, the timeline, and the project scope. If the change is significant, the additional scope is agreed separately before implementation.

Yes, if the work is organized in stages. A completed and paid stage can remain a standalone result where technically possible.

Not always. Some solutions work without additional subscriptions, but Microsoft, Google, hosting providers, APIs, or third-party services may have their own paid plans.

These may include Microsoft 365 or Power BI licenses, hosting, a domain, paid APIs, third-party services, increased limits, or other external infrastructure. If such costs are required, they are agreed separately.

My main tools include Excel, VBA, Power Query, Power Pivot, Power BI, Google Sheets, Google Apps Script, JavaScript, HTML/CSS, Telegram Bot API, and integrations with external APIs.

The choice depends on where the data is stored, who will use the solution, which calculations and automations are required, what access rules apply, and how the solution will be used. The tool is selected for the task, not the other way around.

Yes. Data collection, processing, validation, consolidation, calculations, and final report generation can all be automated.

Yes. Depending on the technology, updates can run on a schedule, by button, by event, or under another agreed condition.

Yes. Updates can run hourly, daily, weekly, or according to another schedule if the selected platform supports it.

Yes, within the technical capabilities of Excel, Google Sheets, Power BI, and the other tools being used. I currently do not work with Big Data platforms such as Hadoop or Spark.

Yes. Dashboards can include KPIs, charts, filters, plan-vs-actual analysis, drill-downs, and other interactive elements.

Yes. They can include formulas, conditions, validations, reference tables, scenarios, and automatic result generation.

Yes. For example, models for budgeting, forecasting, plan-vs-actual analysis, scenario calculations, and other tasks where the logic can be clearly formalized.

Yes. I can work with report publishing, access management, refresh, and report usage in Power BI Service.

Yes. Depending on the task, the solution can use Excel, OneDrive, SharePoint, Teams, and other Microsoft 365 components.

My main focus is Excel, Power BI, Google Apps Script, JavaScript, and web interfaces. I can use Python as a supporting tool when it is justified by a specific task. R is not a primary area of my work.

Yes. Depending on the system, these may include APIs, CRM, ERP, Google Drive, Excel, CSV, Google Sheets, databases, and other accessible sources.

Yes, if the system provides an accessible API or another technical integration method and the client can provide the required access rights.

Yes. Google Forms can serve as a data source for calculations, requests, notifications, reports, and other automations.

Yes. Folder creation, copying, renaming, archiving files, generating links, and certain access-related operations can be automated.

Yes, if the platform provides a suitable API, webhooks, or another available integration mechanism.

Yes. Form data can be sent to Telegram, email, Google Sheets, or several channels at the same time.

Yes. Automatic message creation and sending can be implemented through suitable services or APIs, depending on the task and platform.

Yes, if the required data can be extracted from the document reliably. Values can be extracted, cleaned, validated, matched, and written to spreadsheets or other systems. Accuracy and the processing method depend on the document structure.

External services may change their APIs, authorization methods, pricing, limits, or other rules. In that case, the integration may require adaptation or further development.

Yes. I build web interfaces for working with spreadsheets, forms, files, photos, links, internal processes, and other business data.

Yes. I can improve HTML/CSS/JavaScript websites, forms, responsive interfaces, analytics, and integrations. The main focus is functional business websites and web interfaces rather than complex design-driven web development.

Yes. The interface can be adapted for smartphones and tablets, including navigation, buttons, forms, search, and other elements.

My main focus is mobile web applications and PWAs that work on Android through a browser and can be added to the home screen. Full native Android development for Google Play is not my primary specialization.

Yes, if the solution supports PWA functionality. In that case, it can be added to the home screen and opened separately from a regular browser tab.

Yes. A bot can receive commands, messages, and files, create reminders, forward requests, work with buttons, and launch automated actions.

Yes. Reminders can be sent via Telegram or email based on date, time, status, or another agreed condition.

Yes. Forms can include validation, conditional logic, calculations, selection lists, file uploads, and automatic data submission.

Yes. Depending on the solution, protection can include CAPTCHA or Turnstile, server-side verification, rate limiting, data validation, and other methods.

Access is requested only to the data and systems required for the specific work. Keys, tokens, and other secret parameters should not be stored in publicly accessible code. Test data, limited access rights, and an NDA can be used where appropriate.

Yes. An NDA can be signed at the client's request.

Yes, if the task allows it. Development and testing can use test, modified, or anonymized data with the same structure.

Yes. Depending on the platform, access can be restricted to files, pages, functions, actions, or specific parts of the system.

Yes. Authentication can be implemented through Google or another available mechanism, including checks for approved accounts and user roles.

Any need for continued access is agreed separately. If access is no longer required, it can be revoked, and keys, passwords, or tokens can be changed after the work is completed.

Yes. Corporate colors, logos, terminology, access rules, data structure, and internal requirements can be incorporated.

Yes. I can create validation checks, discrepancy reports, change logs, statuses, and other tools for monitoring data and process quality.

It depends on the project format. The deliverable may be a finished Excel file, Google Sheet, Power BI report, web application, script, source code, instructions, or another agreed result.

Yes, unless agreed otherwise. For solutions transferred to the client, access to formulas, scripts, and working logic generally remains with the client.

Yes, if the technology and access rights allow it. If needed, I can also prepare instructions or explain the solution structure.

This is defined by the terms of the specific project and the agreed handoff scope. Files, code, scripts, documentation, or other materials included in the agreed deliverable are transferred to the client under the agreed terms. Rights to third-party libraries, services, platforms, and other external components remain subject to their own licenses and rules.

The goal is to avoid creating artificial dependency. If the solution can technically operate independently, it should continue working without my permanent involvement. External services, APIs, or infrastructure may be exceptions because they can require separate maintenance.

In many cases, no. Google Workspace, web applications, and some other solutions work in a browser. Certain Excel solutions may require a suitable version of Microsoft Excel.

It depends on the technology. Web applications and Google Workspace generally do not depend on the operating system. Excel VBA on Mac may have technical limitations.

Yes. Ukrainian, English, Russian, or other languages can be implemented if required by the project.

The timeline depends on the scope, complexity, readiness of the source data, and the speed of approving details. Small tasks can be completed quickly, while complex projects may be delivered in stages over a longer period.

Before handoff, the core logic, typical use scenarios, and critical errors are checked. For complex solutions, testing can be performed in stages together with the client using test or real-world scenarios.

If the issue relates to agreed and implemented logic, its cause is analyzed and the correction approach is determined. New requirements or changes to business logic are handled separately from bug fixes.

Yes. Post-launch support, correction of identified issues, consultations, and further improvements are available under agreed terms.

Yes, if the architecture and technology allow it. New functions, modules, reports, or integrations can be added as separate stages.

Yes. If needed, this can be a written guide, diagram, short video, or technical description.

Yes. For more complex solutions, I can provide a short explanation or user training session.

Yes. Most tasks and projects can be completed entirely online.

Yes. Remote cooperation with clients from other countries is possible.

The core logic is built for the specific task. Certain proven technical components may be reused when appropriate and when doing so does not create security or quality issues.

Yes, as a supporting tool in my work. Solution architecture, business logic, validation, testing, and final decisions should not rely solely on automatically generated output.

Yes. The Solutions page includes demonstration cases with examples of implemented tasks. For a specific task, we can also discuss a relevant example or prototype where appropriate and where doing so does not compromise another client’s confidentiality.
