Frequently asked questions

With whatever I can. Preparing project analysis, creating roadmaps, defining business goals, key business values, target users, main features, prioritising.
I can find you similar projects that are already active on the market to benchmark against. I can assist you with creating user personas, mock-ups, user stories, time frame, establishing project status and preparing project estimation. I'll be happy to outline project specification, prepare wireframes, details concerning integrations with external services, API documentation, required features list.
In terms of project development I prepare server-side architecture, front end, back end, graphic and UX design, and digital marketing.
I am also happy to advise my customers in terms of budgeting, scheduling, risk management, and business model creation.

Hiring your own software developers can be a really smart choice, however, recruitment process is time-consuming and the costs of keeping an in-house programming team are very high. You'll probably need to employ your own software engineers sooner or later but hiring a full stack freelancer like me can help you save a lot of money and time (which is basically the same in a business project).

Both have their benefits and flaws. Mobile apps are surely more expensive but can provide you with many more data collecting, monetisation capabilities than web applications. Progressive Web Apps are a good compromise between a mobile and web app — But remember that sooner or later you may need both mobile and web app and when that moment comes I am here for you :)

Well, the most important thing to know is what do you want to accomplish. Why do I need this software? What for? What should it do? Having a clear vision in mind is crucial when ordering a software application. You don't want to spend many months developing it with me without being sure what you need. If you have no experience in app development feel free to contact. I'll also be glad to help you get started, building projects from scratch is nothing new for me.

To give you a precise answer i must prepare a project scope and create a budget. I will tell you how much of that scope can be completed within the budget and I'll be able to estimate how long will it take after at least a month of work. Don't worry, if you're not happy with my work after two weeks you can retract from the project with no penalties, this is my trial period and we believe that any reliable software house should give you one.

I thoroughly monitor my development team and control how much time we spend on each task down to the exact minute. I use web tools to track time spent on the project on hourly basis.
