We’ll help you avoid many concerns like data breaches and loss through our Fastify software solutions. Check out our client testimonials and portfolio, and if you have any questions, don’t hesitate to contact us.

Security with an escrow account
You can employ our escrow partner as a middleman to secure your costs. Before we start development, we may agree on the terms upon which the escrow agent releases your payment to us. With a minimal escrow fee, you can sleep well knowing you pay only for the job done correctly.

Improved ROI with a UX audit
Our UX audit shows you what upsets your users and holds back the success of your Fastify or other technology-related solutions. This approach is the best way to cut development expenses and improve your ROI in the long run. In the UX audit, we analyze the design of your software solution to enhance user flows. At the same time, we eliminate your users’ pain points and improper design practices. Learn more in this UX presentation.

Our Customers Say
The Keenethics team performed well alongside our internal team. Their intermediate developers produced high-quality code and efficient scripts that emphasized the app’s performance. The team was highly accessible and responded to any inquiries within 30 minutes. Keenethics accommodated two weeks of 10–12-hour days to help us meet our strict deadlines. They truly invested themselves in the project. Customers can expect a highly productive team that delivers high-quality products at competitive rates.
I’ve been working with Keenethics since 2017, and they grew impressively since then. Keenethics is great in comparison with other Ukrainian software development companies. They have decent project managers and very proactive developers. It’s always nice to work with developers who can solve your issues before you even anticipate them.
In a software partner, I value liability, trustworthiness, and transparency the most. I can say that all three are present in Keenethics. Our work was effective, and we definitely demonstrated a great deal of progress as the project grew larger. The most valuable thing about Keenethics is their attitude, both to partners and to employees. Our cooperation has never been stained by conflicts or mistrust. By contrast, it was very transparent, friendly, and thus, effective.
The greatest thing about Keenethics is that this company is all about ideas. They do not strive for money only. These people aim to make a difference in the software world. They promote ethical values and show others how to meet Tech4Good demands. They were so excited by how new technologies can be used for the common good that they even asked me for an interview that was published on their blog. It has been a pleasure to work with them.
