ein-des-ein

Ein-Des-Ein is a web and mobile app development agency based in Poland with 80+ professionals and 100 delivered products. Founded by Mykhailo Chepurniak (CEO with 10+ years experience), the company builds iOS and Android apps, web applications, and UI/UX design across fintech, healthcare, e-commerce, logistics, and other verticals. The team is distributed and works with startups and established companies alike, often stepping in early-stage—moving concepts from paper to functioning products.

Services and capabilities

Ein-Des-Ein's core offering splits into four areas: full-cycle web development, native mobile apps (iOS and Android), UI/UX design, and dedicated team engagement. On the web side, they build dynamic web apps for process automation and data management, custom websites, and handle API integration with third-party services. Mobile work emphasizes performance, security, and intuitive design with post-launch monitoring. Their UI/UX practice includes wireframing, prototyping, user roadmaps, and usability testing with real users.

The backend stack leans Node.js, Python, Java, PHP, and Go. Frontend: React, Vue, Angular. Mobile: Swift, Kotlin, Flutter, KMM, and Compose. They work with AWS, Firebase, Kubernetes, Azure DevOps. The team also handles DevOps and CI/CD infrastructure. About 85% of their developer roster is senior-level; standard tasks go to middle-level engineers with industry-specific knowledge.

Notable work

Portfolio includes Bobbie (offline invoice approval and receipt using Kotlin, NodeJS, Swift on AWS), Abraaj Water (water delivery platform with client app and CRM integrating SAP, built in Kotlin, NodeJS, Swift), Scholarcy (SaaS AI-powered article summarizer in NestJS, NodeJS, React, TypeScript), and Apiway (website and identity for an API integration platform). Client testimonials cite specific outcomes: Supplement Stax launched a new platform in under a year and achieved positive ROI; DrugTrack went from concept to fully-functioning subscription app; iPlena (AI startup) valued the team's proactive suggestions beyond spec execution; p2connct praised smooth collaboration and results.

How they work

Engagement begins with a free 1-hour consultation where the team assesses project scope, complexity, and challenges. Ein-Des-Ein typically provides a discovery phase covering goals, requirements, and roadmap before development starts. The process flows: contact → send requirements → review CVs → interview candidates → sign contract → start work. Communication uses Slack and regular review meetings; clients get early roadmaps, progress reports, and demo sessions. One cited engagement (logistics route optimization) involved continuous updates on milestones and challenges, with the client actively involved in decision-making. A professional sprint with a senior developer starts from $2,500. Simple apps may cost $10,000–$50,000; complex ones $50,000 and up. Timelines: simple products 3–6 months, complex 6+ months to over a year.
