I develop mobile‑first applications and scalable APIs that bridge user‑friendly front‑ends with robust .NET back‑end services. My focus is on delivering cross‑platform apps (Android, iOS, Windows, macOS) using Flutter and .NET MAUI, paired with clean, modular APIs built in ASP.NET Core. I leverage modern practices like microservice architecture, containerization and gRPC/REST communication to ensure your product is secure, maintainable and cloud‑ready.
What I deliver
- Cross‑platform mobile apps: Single‑codebase apps built in Flutter and .NET MAUI that run natively on Android, iOS and desktop. Features include real‑time chat, biometric authentication and responsive UIs for foldables and wearables.
- Full‑stack back‑ends: Scalable APIs built with ASP.NET Core, leveraging microservices, gRPC and RESTful endpoints. Containerization with Docker/Kubernetes enables easy deployment and scaling.
- Cloud and DevOps integration: Deployment pipelines using Azure Functions and DevOps for CI/CD, plus integration with managed databases like SQL Server and Cosmos DB.
- Secure & performant architecture: Implementation of authentication/authorization (OAuth, JWT) and resilient patterns (caching, circuit breakers) to keep your app fast and secure.
Why clients choose me
- Modern tech stack: Up‑to‑date with .NET 8 improvements and cross‑platform trends such as .NET MAUI, microservices and cloud‑native development.
- User‑centric design: I prioritize intuitive UX and responsive layouts, ensuring apps perform smoothly on various devices and screen sizes.
- Transparent communication: Clear timelines, milestone‑based delivery and proactive updates help you stay informed.
- Long‑term partnership: From MVP to enterprise‑grade product, I provide ongoing support and optimization.
Let’s build a mobile‑first solution with a powerful .NET back‑end that scales with your business and delights your users.

I am a Unity Game Developer with 7 years of professional Unity development experience, I specialize in building mobile games, multiplayer systems, AR experiences, and 2D/3D games that go beyond the editor, and into the hands of real players.
My portfolio includes 4 live published titles on Steam and Google Play Store, delivered end-to-end, from initial architecture to final store submission. I have built games from scratch, stepped into half-finished projects other developers abandoned, and shipped live updates without breaking what was already working.
My expertise covers Photon Fusion, Unity Netcode, Mirror, AR Foundation, Firebase, PlayFab, URP, HDRP, and the full Unity toolchain. I plan architecture before writing a single line of code, test under real player conditions, and communicate proactively, no surprises at the deadline.
STRENGTHS:
✔ 7+ years of dedicated Unity development across mobile, multiplayer, AR, 2D and 3D
✔ 4 live published games on Steam and Google Play Store, not demos, real products with real players
✔ Full-cycle delivery, concept, architecture, development, publishing, and post-launch support
✔ Multiplayer specialist, systems built and debugged under real player conditions, not just local testing
✔ Project rescue expert, I take over broken or abandoned Unity projects and deliver them
✔ Performance-first approach, optimized for real-world devices, not just high-end test machines
✔ Honest scoping, if something isn't feasible in your timeline or budget, I tell you before starting, not at delivery
✔ Proactive communication, you hear about any issue from me before the deadline, never after
SERVICES
