Founder-led staff augmentation of AI-Ready Senior Developers and Dedicated Teams in 60 hours
UASOFTDEV is a founder-led staff augmentation of AI-Ready Dedicated Teams and Senior Software Engineers for small-mid companies. We believe AI doesn't replace experienced engineers. It makes the right engineers dramatically more effective. That's why every developer we provide uses AI as part of their daily workflow with tools like Claude, Cursor and GitHub Copilot, while all architecture, technical decisions, code reviews and production releases remain under experienced human ownership. Main engagement models. Staff Augmentation for companies looking to extend their existing engineering team with senior talent, and AI-Ready Dedicated Teams for businesses that need a complete delivery team with technical leadership capable of owning products, features or entire engineering initiatives. Every engagement is led directly by our Founders. Aleksey, CEO, works closely with clients to understand product goals, business priorities and team dynamics. Oleksandr, CTO, personally evaluates every engineer for technical excellence, communication and problem-solving skills. Our work is built around four core values: quality, clarity, transparency and a personalized approach to every client engagement. The process is simple: after a discovery call, we match engineers to your technology stack, product domain and culture, present a CTO-vetted shortlist and run contracting alongside onboarding. Staffing typically happens within 60 hours. Today, our teams support startups and product companies across Europe, UK and North America. UASOFTDEV's track record includes a 97% first-candidate acceptance rate, a 95.65% first-match success rate and an average client engagement of over 13 months. Founders respond to critical issues within two working hours. Whether you need one senior engineer or an AI-Ready Dedicated Team, our goal is the same: help you ship faster with engineers who communicate clearly, contribute from day one and solve complex problems independently.

Raising Potentials
We cannot predict the future - but we make it possible. Future viability is the most important characteristic a company can have today. In an ever-changing world, the adaptable survive. Those who react nimbly and flexibly to new influences. Those who recognize and anticipate trends. Survival of the fittest. The Darwinism of companies. Today's "hot shit" is already yesterday's news tomorrow. That's why keeen orchestrates the disciplines of marketing, technology, and experience design into overarching added values. Of course, not everyone plays the same tune, but the result is more than the sum of its parts. This is how we unlock our clients' potential for the future and enrich the lives of millions of people with our work. We believe that truly good digital products can only be created when the user is addressed holistically. Three essential factors play a role here: The head decides rationally about performance. Technology must work, facts must be right. We build the technological platforms that carry brands. As a TYPO3 Gold Member and Shopware Business Partner, we are a reliable, competent contact for digital ecosystems, websites, and e-commerce development. Marketing stages the authentic appearance of a brand or product. We develop the emotional appeal, message, and tonality, and ensure consistent positioning in the market. A user experience that makes you want more is intuitive to use and visually appealing. We design the user experience that excites people.
