4.9(18 reviews)PARTNER IN CRIME FOR STRONG BUSINESSES. Websites · Branding · Software
Highly recommendedTop awardedWebsites · Branding · Software Website: https://www.u1core.com/ Book a call: https://calendly.com/hello-u1core/30min Most companies outgrow their digital before they notice. The business is strong, the team is good, the product works. But the website is still the first version, operations still live in spreadsheets, and the brand says nothing a competitor couldn't say. That's where we come in. WHAT WE DO · Websites — marketing sites, landing pages and platforms that sell before your team has to · Branding — identity and design systems that position you at the level you actually operate at · Software — web and mobile products, internal tools and operational systems that replace manual work WHY ONE TEAM Brand agencies do brand. Product studios do product. Outsourcing firms write code. The real problems sit between those disciplines — which is why we do all of it, under one contract, with one person accountable for the result. WHO WE WORK WITH Companies with real revenue and a team in place: founders and owners scaling past their first system, operators rebuilding for growth, and businesses entering a new market. WHERE WE'VE PROVEN IT $720M+ processed through a platform we built. Classified marketplaces with millions of listings. Trading exchanges and auction systems running in production. SaaS, fintech and marketplace products across 40+ projects. HOW WE START With a diagnostic, not a proposal. We look at your website, brand and operations, show where you lose trust, traffic and time — and what to fix first. LET'S TALK IF your business is strong but your website, brand or operations don't play at the same level yet.Looking for work in .NET DevelopmentLocated in London, United KingdomFrom €5,000 for .NET DevelopmentWorked in E-commerce (+19)Speaks English11-50 membersUASOFTDEV
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 .NET DevelopmentLocated in London, United Kingdom (+4)From €3,000 for .NET DevelopmentWorked in Hospitals & Healthcare (+3)Speaks English11-50 membersTRIARE
