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.1 work in Flutter Software DevelopmentLocated in New York, United States (+4)From €3,000 for Flutter Software DevelopmentWorked in Hospitals & Healthcare (+3)Speaks English11-50 membersInstinctools

5(4 reviews)Top awarded75+ Mobile Apps Shipped. 12+ Apps Featured by Apple & Google. 20M+ Downloads. TouchZen has shipped 75+ mobile apps since 2014 with 20M+ collective downloads and 12+ apps featured by Apple and Google, including SHRED (Apple's App of the Day) and FullyRaw (#1 paid app in Food & Drink within one week of launch). We're not a dev shop that takes your wireframes and starts coding. Every project starts with competitive analysis and market research, so we understand your users, your competitors, and where your app fits before a single screen is designed. From there, we build full interactive prototypes in Figma, so you can see and test the complete experience before development begins and before the big spend starts. Our team specializes in iOS, Android, Flutter, and React Native, with senior engineers who stay on your project from kickoff to launch and beyond. We work with early-stage startups building their first MVP and growth-stage companies scaling to millions of users, including Beachbody, Shred, JetBay, Amalfi Jets, and GetCover How we keep budgets sane without cutting corners: Our strategy, design, and project leadership are based in California. Your point of contact is always senior and always stateside. Part of the development is handled by a vetted global engineering team we've worked with for years, not random freelancers spun up for your project. This hybrid model means you get the communication, accountability, and quality of a US agency without the $300K price tag that usually comes with it. It's also why we can honestly tell you what not to build, because we're not padding scope to justify overhead. A lot of our clients come to us after a bad experience with another agency, with missed deadlines, junior developers swapped in mid-project, or code that couldn't scale past 10K users. We built TouchZen to be the opposite of that: a senior team, a research-first process, and a founder who personally oversees every engagement.Looking for work in Flutter Software DevelopmentLocated in Irvine, United StatesFrom €10,000 for Flutter Software DevelopmentWorked in Travel & Leisure (+6)Speaks English11-50 membersDifferenz System
