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.10 works in Web ApplicationLocated in Timișoara, Romania (+2)From €5,000 for Web ApplicationWorked in Automotive (+18)Speaks English, French(+2)11-50 membersDebut Infotech

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.4 works in Web ApplicationLocated in Berlin, Germany (+4)From €10,000 for Web ApplicationWorked in Hospitals & Healthcare (+3)Speaks English11-50 membersKeyToTech
