UASOFTDEV
5(3 reviews)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.Looking for work in NextJS DevelopmentLocated in London, United Kingdom (+4)From €3,000 for NextJS DevelopmentWorked in Hospitals & Healthcare (+3)Speaks English11-50 membersScalara Labs
