Hello, my name is Andrei Maksimovich. I’m a Senior Full-Stack Mobile Software Engineer, and this website represents me and my company through which I provide B2B services to my clients.
I am a passionate full-stack mobile software engineer with over ten years of experience. I specialise in building full-stack mobile applications (Android/iOS/Mobile-Web) with backends in Node.js/Spring-Boot/AWS/Firebase/Linux-VPS, backend systems, CI/CD pipelines, business process automation tools, and integrations with external services.
I have a deep understanding of the technologies and systems behind mobile and web projects – from low-level optimisations for mobile devices to multi-regional backend scaling with redundancy, autoscaling, automated deployment, and backup systems.
What I can do for you
Full-Stack Mobile App Development
I design and build complete mobile solutions that transform ideas into polished, production-ready applications.
- Cross-Platform Applications – I develop high-quality React Native apps that run on iOS, Android, and the mobile web from a single codebase.
- Native iOS & Android Apps – When needed, I build fully native applications with maximum performance and deep platform integration.
- Custom React Native Plugins – I create bespoke native modules for Android, iOS, and Web to extend React Native with advanced or unconventional functionality.
- Framework & SDK Integrations – I integrate third-party services, SDKs, and frameworks into new or existing React Native applications.
- Mobile Web Adaptation – I port existing mobile apps to the web, optimizing performance and UI for mobile browsers.
- Continuous Support & Feature Development – I provide ongoing updates, improvements, bug fixes, and major feature expansions.
- Backend Engineering – I build secure, scalable backend systems using Node.js, Spring-Boot, AWS, Firebase, and Linux servers to support mobile applications.
Business-Oriented Mobile App Development & Systems Engineering
I design, build, update, and maintain backend systems, internal platforms, and mobile applications that support and optimize everyday business operations.
- Custom Mobile Applications for Business – Not all apps are customer-facing. I develop specialized mobile tools for employees, partners, or clients, fully integrated into your existing infrastructure. These apps streamline workflows, improve productivity, and make field operations easier and more efficient.
- Data Import, Export & Migration – I provide support for transferring data between systems, platforms, or services. I ensure accuracy, consistency, and minimal disruption.
- Custom Tooling & Internal Systems – I build custom tools and automation systems that reduce manual work, eliminate repetitive tasks, minimize human error, and speed up business processes. From dashboards to importers, workers, and automated pipelines, I create solutions that fit your exact workflow.
If your business needs mobile tools, backend support, or process automation tailored to your specific operations, I provide the engineering expertise to make it happen.
Unity 3D Engineering
I offer full-cycle Unity engineering services for games, interactive applications, and cross-platform experiences.
- Core Gameplay Systems – I design and implement robust, scalable gameplay mechanics tailored to your project needs.
- Custom Unity Tools & Editors – I build production-boosting tools, custom inspectors, asset processors, and editor extensions.
- Asset Pipeline Engineering – I create automated pipelines for importing, optimizing, bundling, and delivering art and audio assets.
- Cross-Platform Porting – I port Unity mobile games to the web (WebGL) and other platforms, optimizing for size, performance, and compatibility.
- Performance Optimization – I improve framerates, memory usage, and responsiveness on mobile and web platforms.
- CI/CD Automation – I set up automated Unity build pipelines, cloud or local, covering testing, packaging, and deployment.
- Native Plugin Development – I build custom native plugins for iOS, Android, and WebGL to extend Unity’s capabilities beyond the engine.
- Native Framework Integration – I connect Unity projects with native platform code and third-party services (analytics, payments, sensors, system APIs).
- Backend Development – I create backend services to support live features, authentication, data storage, leaderboards, analytics, and game logic.
From small indie prototypes to production-grade, cross-platform applications, I provide the technical expertise to build, optimize, and scale your Unity-based products.
