Discover .NET developers and agencies

I’m Dominik Lubański (call me Dominik). I help startups and businesses build scalable SaaS products, AI-powered applications, RAG systems, and workflow automation solutions, backed by 11 years of full-stack engineering experience and 5 years specializing in AI. I combine deep engineering expertise with AI-powered development tools like Claude to turn complex business ideas into reliable, production-ready solutions—delivering faster without compromising quality.

We help growing companies build scalable operational platforms, business systems, and AI-enabled workflows for integration-heavy and operationally complex environments. What sets Celadonsoft apart is our clarity before development: we start with discovery, solution design, and business analysis to define architecture, workflows, integrations, priorities, and the right development scope before build begins. This foundation allows us to deliver predictably for complex systems by combining product management, QA, solution design, and senior engineering, keeping complex software projects transparent, structured, and predictable from discovery to release. We are built for real business complexity and work best with growing and established companies that need operational platforms, multi-role systems, complex integrations, internal workflows, and software that supports long-term growth and operational scale. At the same time, our senior engineers use AI to accelerate delivery and reduce repetitive work while keeping architecture, technical decisions, scalability, and quality under senior engineering control. We primarily work with companies in Food & Beverage, Real Estate, and FinTech, and our strongest experience includes restaurant chains, multi-location businesses, operational platforms, workflow-heavy systems, and customer-facing digital products tied to core business operations.

Metatech Official is a mobile app development company specializing in complete digital product solutions for startups, small and medium-sized businesses, entrepreneurs, and established organizations. Since 2018, we have helped businesses transform concepts into reliable, scalable, and intuitive mobile applications aligned with their operational objectives and customer requirements. Our mobile app development services span the complete product journey, including research, planning, UI/UX design, development, testing, deployment, maintenance, and ongoing improvements. Our expertise includes Android and iOS app development, cross-platform solutions, backend development, API integration, database architecture, cloud services, quality assurance, deployment, application optimization, and long-term technical support. Every project is approached according to its individual business and technical requirements rather than through a one-size-fits-all process. Before development begins, we consider factors such as the target market, business model, user journeys, integrations, technical requirements, scalability needs, and long-term product plans. This helps us build applications that address immediate requirements while providing a foundation for future growth. Our team has experience developing applications and digital platforms across numerous industries. These include ecommerce, marketplaces, food delivery, logistics, healthcare, fintech, trading, Web3, transportation, real estate, dating, fitness, education, IoT, augmented reality, hospitality, and other specialized business solutions. For ecommerce and marketplace applications, we develop functionality such as product listings, advanced search, filtering, customer accounts, shopping carts, checkout systems, payment gateways, order processing, vendor panels, inventory integration, push notifications, and administrative dashboards. We focus on creating straightforward shopping experiences while providing businesses with the tools required to manage their operations efficiently. For logistics and delivery businesses, we create interconnected platforms that support customers, merchants, drivers, dispatch teams, and administrators. Features can include live order tracking, dispatch management, shipment status updates, driver management, notifications, routing functionality, and operational dashboards. Connecting these roles within a unified platform helps streamline complex delivery processes. Our healthcare, fitness, and wellness solutions can include appointment booking, telemedicine platforms, patient portals, health and fitness tracking, reminders, progress monitoring, dashboards, and customized workflows. For fintech and trading products, we develop solutions around secure architectures, account management, backend systems, API integrations, structured user journeys, and transaction-oriented functionality according to project specifications. We also develop Web3 and blockchain applications, including cryptocurrency wallets, multi-chain wallets, token platforms, blockchain integrations, smart contract connections, decentralized application interfaces, and supporting backend infrastructure. Our approach is focused on presenting complex blockchain functionality through interfaces that remain understandable and accessible to everyday users. UI/UX plays an important role throughout our development process. Our designers create wireframes, user journeys, navigation structures, responsive interfaces, and consistent visual systems with usability in mind. The goal is to produce applications that look professional while allowing users to complete tasks efficiently across different screen sizes and devices. Our technical teams handle the underlying infrastructure required to operate modern applications, including backend development, APIs, databases, authentication, authorization, role-based permissions, third-party integrations, and administration systems. We emphasize organized and maintainable architecture so products can accommodate additional users, features, integrations, and changing business requirements over time. Quality assurance is incorporated into the development lifecycle rather than treated solely as a final step. Applications are evaluated for functionality, user flows, integrations, device compatibility, responsiveness, and performance before release. Following deployment, we can provide ongoing maintenance, issue resolution, updates, feature development, technical improvements, and performance optimization. Since establishing our services in 2018, Metatech Official has expanded its capabilities across mobile applications, custom software, web technologies, and emerging digital solutions. Our aim is to develop technology that delivers measurable practical value, whether a business wants to improve customer interaction, automate internal processes, introduce a new digital service, or build an entirely new product. Beyond mobile development, we also offer website development, web application development, UI/UX design, SEO, PPC management, and digital marketing services. This enables businesses to combine product development and digital growth initiatives through a single technology partner. Companies seeking experienced app developers can engage Metatech Official for projects ranging from startup MVPs and proof-of-concept applications to large-scale customer platforms and enterprise systems. As a mobile app development agency, we emphasize organized planning, transparent communication, appropriate technology selection, scalable architecture, and consistent execution throughout the development process.
