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 C++ DevelopmentLocated in London, United KingdomFrom €5,000 for C++ DevelopmentWorked in Food (+18)Speaks English11-50 membersGRM Digital

We are committed to delivering business value so we agree upfront on a defined outcome, a measurable milestone or a capability you can use.

Once the direction is set, the work shifts to delivering production software and keeping it dependable long after go-live.

4.8(15 reviews)Growing with Technology
Highly recommendedTop awardedAbout Ascendro Ascendro is a German-Romanian engineering company that builds and runs software-critical systems. Around 45 senior engineers, working from Timisoara and Germany. Most software vendors treat go-live as the finish line: the system is delivered and operating it becomes someone else's problem. We work the other way around. We take end-to-end responsibility for architecture, delivery and production operations - uptime, incidents, deployments, security - and stay accountable for how the platform behaves for years afterwards. This matters most when software becomes business-critical faster than the infrastructure around it matured. A pilot turns into a production service. The internal team knows the domain but was never sized to run a platform 24/7. That is where we are useful. We do not rebuild operations for every client. Our DevOps Foundation is a reusable, cloud-agnostic backbone for CI/CD, monitoring, logging, authentication and backups, already running across multiple live environments. It moves systems into stable production without a client having to hire a platform team - and we can operate it afterwards. Track record BMW DriveNow - the city-scale shared mobility platform; Ariston and Wolf - connected heating and manufacturing-critical environments; Thinksurance - a regulated, high-availability insurance distribution platform; Samsung - release management for large-scale software delivery; Several of these engagements have run for many years. We are certified to ISO 27001 and TISAX, staff senior squads rather than interchangeable headcount, keep 85-90% engineer retention, and give clients direct founder access instead of account managers.Looking for work in C++ DevelopmentLocated in London, United Kingdom (+2)From €1,000 for C++ DevelopmentWorked in Automotive (+18)Speaks English, French(+2)11-50 membersSigli

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.
