Our contribution to the community

As a company, we believe in the importance of giving back to the community.

Many communities still lack access to technology, education, and other necessary resources. That’s why we believe that IT companies have a unique opportunity to make a positive impact in their communities by leveraging their expertise and resources.

As we’ve journeyed towards this belief, we’ve established three distinct brands as our contribution to the “give back” equation. We’re proud to share our commitment to serving the community through these initiatives.

Frequently Asked Questions

What kind of projects does JSGuru do?

Our company is a full product development agency that specializes in building mobile and web applications for our clients. While these two types of projects are the most common, we also excel in creating desktop apps, web extensions, and IoT software.

How do I get started?

The easiest way to get started is to reach out to us through our contact form. Please be descriptive and precise as much as possible. Having all the info will give us the opportunity to properly prepare for our first meeting. Once your initial inputs are reviewed, our senior staff will reply with possible questions and time slot suggestions for the first meeting.

Do you work with other tech stacks besides JavaScript?

Yes, we also work with other technologies like Flutter, PHP, Java and Python.

Hourly basis or fixed price?

Both staff augmentation and fixed-price options are available, and the choice between the two depends on the client’s preferences and requirements. Typically, hourly rates are utilized for staff augmentation, while fixed-price is a better option for projects built from scratch. In the latter case, it is crucial that we receive a detailed project specification, covering all aspects of the project.

How can I test the work done?

We prioritize transparency and communication throughout our work with clients, ensuring that the latest practices and standards are applied to your project. Regular updates on the project’s progress and the quality of work done will be provided. Depending on the project’s complexity, monitoring can be performed in various ways. For instance, mobile apps have test versions that are only accessible to authorized personnel. Rest assured, we will work closely with you to determine the best approach for keeping you informed about your project.

What happens when the project itself is complete?

When we bring the project to its completion stages, we have a set of procedures for project delivery, code ownership transition and general know-how transfer. This usually takes a week or two to complete. Sometimes it can take longer, depending on the complexity…
