I am a .NET full stack developer and software architect with 8+ years of experience building scalable web applications using ASP.NET Core, Angular, C#, TypeScript, Microsoft SQL Server, Azure, and modern cloud technologies. Across 35+ projects in defence, renewable energy, fintech, e-commerce, and enterprise SaaS development I have delivered systems that handle real production load, not just demo traffic. What I build as a .NET full stack developer My deepest work is in ASP.NET Core back-end development. I spent years as the lead .NET full stack developer on a platform managing thousands of wind and solar energy installations globally, processing massive volumes of real-time data, building microservices on .NET Core and Azure, and reducing critical downtime incidents by over 40% through improved monitoring and analytics. On another project I built a Loan Origination System in ASP.NET Core that automated the entire loan lifecycle from lead capture to loan issuance, integrating with HubSpot, external CRMs, and RESTful APIs on Microsoft Azure. The client went from manual processing to a fully automated fintech pipeline handling 550+ active applications, cutting processing time by 60%. ASP.NET developer work across enterprise and defence Some of my most complex work as an ASP.NET developer has been in defence and industrial sectors. I modernized a legacy web platform for a company managing 36 high-uptime naval fleet assets, warships that cannot afford downtime. The ASP.NET MVC rebuild reduced manual reporting time by 70% and enabled real-time asset tracking, secure document storage, and streamlined access to sensitive operational data. On another engagement I took over a large workplace management SaaS development project built by a single developer who had left, no documentation, weekly outages, daily hotfixes. I stabilized the ASP.NET Core back-end, eliminated the performance bottlenecks, and reduced unplanned incidents from weekly to zero within two months. ASP.NET Zero and enterprise acceleration ASP.NET Zero is my go-to when enterprise clients need multi-tenancy, role-based permissions, and audit logging without spending the first three sprints on boilerplate. I have used it to accelerate SaaS development on projects in pharma automation, workplace management software, and industrial IoT, cutting initial setup time by 3+ weeks and letting the team focus on actual business logic from day one. On average my clients ship their first production release 30% faster on ASP.NET Zero compared to building from scratch. Full-stack web development across the whole system As a .NET full stack developer I own the entire delivery, ASP.NET Core back-end, Angular or React front-end with clean web design, Microsoft SQL Server and PostgreSQL database design, and Azure infrastructure. I built a Shopify fulfillment tool in ASP.NET Core and React that reduced packing mistakes to zero and cut order processing time by 35%, integrating barcode scanning, inventory management, and connections to 8+ shipping providers. I delivered a fleet management system in .NET Core and Angular handling 1,250+ assets and 845 active rentals simultaneously, with automated reporting that saved operations teams 10+ hours per week. On the front end I work with Angular, React, TypeScript, JavaScript, Next.js, HTML, CSS, Bootstrap, and RESTful API integration, connecting them cleanly to .NET back-ends without creating maintenance nightmares six months later. C# and .NET developer engineering that goes deep Back-end development across 8 years as a .NET developer means I have seen what breaks under real load. I cut a US e-commerce platform's page load time from 8 seconds to 2, directly contributing to a 2x increase in sales. I optimize Microsoft SQL Server and PostgreSQL queries, regularly reducing query execution times by 60-80%, design database schemas that support complex reporting, and build API integration layers connecting .NET systems to CRMs, ERPs, payment gateways, and third-party platforms. I work with Node.js for event-driven services, TypeScript to keep large codebases maintainable, and Python or PHP when projects need scripting layers alongside the core .NET stack. For web development infrastructure I use Microsoft Azure and Amazon Web Services, Docker containers, microservices architecture, and CI/CD pipelines that reduced deployment time by 50% for several enterprise clients. Why clients come back I have worked with clients in Germany, the USA, Australia, the UK, Norway, Denmark, and the Netherlands across renewable energy, defence, fintech, e-commerce, and industrial IoT. What stays the same: I ask the right questions before writing the first line of code, flag problems early, and deliver .NET full stack applications that work in production, not just in development. If you are scaling a SaaS product, modernizing a legacy system, or need a .NET full stack developer your team can build on, let us talk.

I help ambitious founders and scale-ups launch high-performance mobile products by delivering scalable Mobile App Development that reduces technical debt by 40% and cuts time-to-market by up to 3 months. If you are looking for a seasoned React Native expert to bridge the gap between complex business requirements and a seamless user experience, you have found the right iOS Android Developer. In today’s digital-first economy, a mobile app is your most significant customer touchpoint. It needs to be fast, stable, and intuitive. I have spent years refining my craft in Mobile App Development, focusing on building robust, cross-platform solutions that perform under pressure. Whether you are building an MVP or scaling an existing ecosystem, my goal is to ensure your product survives the challenges of growth while staying ahead of the competition. When I approach Mobile App Development, I treat your project as if it were my own. I specialize in React Native because it allows for high-velocity iteration without sacrificing the native feel users demand. By leveraging TypeScript alongside Expo or bare React Native workflows, I create a Scalable architecture that ensures your app remains maintainable. I understand that your Requirements are unique from complex API integration with REST APIs and Supabase to real-time Firebase backends and intricate Push notifications. My role as your iOS Android Developer is to handle the heavy lifting so you can focus on strategy. Quality Mobile App Development is about the entire lifecycle. My process covers everything from initial UI/UX implementation and Performance optimization to the final App Store and Google Play submission. I have navigated review guidelines for Apple and Google hundreds of times, meaning I know exactly what is required to get your app live without the headaches of repeated rejections. Whether we are utilizing Swift or Kotlin for native performance hooks or working deep in the Node.js stack for custom backends, I ensure the transition from code to user device is frictionless. I am often looking for partners who value precision. My track record as an iOS Android Developer proves that I can handle the nuances of platforms. While my primary expertise lies in React Native, I bring a broad background in full stack developer methodologies, including Laravel, Python, and JavaScript. I have seen projects where a Flutter developer might have been a good fit, but I often demonstrate why a well-architected React Native solution offers better long-term flexibility for teams invested in the React ecosystem. My expertise extends to iOS Development, Android App Development, and integrating advanced Smartphone features like camera processing and biometric security. My workflow is built for modern teams. Independent work is my standard. I prioritize API integration and Performance optimization as a Must-have rather than an afterthought. If you have an existing codebase that needs an audit, I am ready to identify bottlenecks in your Scalable architecture and polish your UI/UX implementation to drive conversion. I believe Mobile App Development should be a collaborative, transparent journey. Beyond technical execution, I act as a product consultant. I help you decide which features are necessary for your v1, preventing "feature creep" that often delays launch. I have worked with everything from E commerce app development to complex SaaS solutions. If you are looking for an iOS Android Developer who understands that code is a business asset rather than a sunk cost, my approach will resonate with you. In the world of App Development, documentation is critical. When I hand over a project, you are not left with "black box" code. You receive a fully documented repository that any future Mobile app developer can navigate immediately. I use Firebase for rapid prototyping and Supabase when deep relational data structures are needed. I take great pride in the Mobile App experiences I create. I’ve seen projects move from sketches to thousands of daily users. I’m currently looking for innovative projects where my skills make a measurable difference. If you have an existing App Development hurdle, let’s solve it together. My communication is direct, and my focus is always on your outcome. From the first line of code to the final store approval, I am there to guide your project. I’m available for a 30–60 minute consultation to review your React Native or mobile app development needs. We can align on technical direction, delivery approach, and realistic timelines, after which I’ll outline a clear execution plan and cost structure. I’d be glad to collaborate. Let’s connect and turn your ideas into a top-tier mobile product.

I help businesses maintain and scale existing Laravel/PHP platforms and internal systems (15+ years in web development). Best fit: long-term development & technical ownership (3+ month engagements), not one-off tasks. Core areas: feature development, production support, performance optimization, refactoring, legacy modernization, API integrations. I work with a small in-house team (backend, frontend, QA) to provide reliable long-term support when needed. Recent relevant work: - Maintenance and modernization of legacy internal systems (stability, speed, technical debt reduction) - PIM / product data platforms managing 300,000+ SKUs with complex workflows - Complex multi-tenant SaaS platforms with admin dashboards, permissions, and background processing - AI-powered SaaS features (automation, intelligent search, data enrichment) - Enterprise integrations (Shopify, SAP, Salesforce, Stripe, internal APIs) Tech stack: PHP (Laravel/Symfony), Vue/React, SQL/MySQL/PostgreSQL/NoSQL, AWS, queues & background workers. Selected outcomes: - Page load time improved by 45% (2.2s → 1.2s) - API response time reduced from 300ms to under 150ms - Uptime improved to 99.99% for business-critical platforms - Automated test coverage increased to 90%+ Security & compliance awareness: encryption in transit/at rest, GDPR-ready systems, secure payment workflows (PCI principles). If you have an existing Laravel/PHP system that needs long-term ownership and steady development, let’s discuss your roadmap.

🌟8+ Years Experience | 50+ Projects | 20,000+ Hours | $900K+ Earned | Upwork Top Performer | Flutter Developer | Mobile App Developer I’m a Flutter developer, mobile app developer, full stack developer, and web developer with 8+ years of experience building, fixing, and scaling mobile products for startups and growing companies. My work spans mobile app development, web development, and backend-connected product work, with a strong focus on clean architecture, smooth user experience, reliable delivery, and scalable app development. I’ve worked across Flutter, Flutter Dart, Flutter Firebase, React, React Native, Xamarin developer projects, Xamarin Forms, Xamarin.Forms, .NET MAUI developer builds, Swift developer work, SwiftUI, iOS, Android, iOS developer tasks, iOS Swift, Android developer tasks, Android Kotlin, Kotlin, native app developer projects, AI app development, MVP development, API integration, and cross platform mobile app architecture. I also support teams that need a practical full stack developer who can connect mobile apps with APIs, dashboards, cloud services, and web systems without slowing the project down. That mix of mobile app development and web development lets me work across the full product, not just one part of it. On Upwork, I’ve delivered 50+ projects, earned $800K+, and worked 20,000+ hours helping clients launch MVPs, modernize old apps, fix unstable codebases, and move products into production. That experience taught me how to balance speed with quality, especially when a project needs to ship quickly but still be stable enough for real users. It also taught me how to work with different teams, different product stages, and different technical constraints without losing momentum. For new products, I help with MVP development from concept to launch. For existing products, I step in to improve architecture, refactor weak areas, and make the app easier to maintain and scale. If you’re building a cross platform mobile app, I can help choose the right direction between Flutter, React Native, .NET MAUI, Xamarin migration, or native app development depending on the product goals, timeline, and long-term plan. I focus on making those choices practical, not trendy, so the app can grow without becoming harder to manage. I’m also a strong fit for AI app development projects where the product needs more than a basic interface. That might mean smart workflows, automated actions, backend logic, or API integration that connects the app to real business systems. In those projects, I pay close attention to stability, data flow, security, and the user experience, because a useful feature only matters if it works reliably in production. 💡 Areas I specialize in - SaaS and startup MVP development - from idea to production-ready MVP. - Cross platform mobile app architecture - Flutter, React Native, and .NET MAUI. - App modernization and legacy migration - Xamarin to .NET MAUI, Flutter, or React Native. - API integration and backend connectivity - for apps that need stable data flow and real-time features. - AI app development and product automation - for teams that want smarter app experiences. - Continuous delivery, refactoring, and codebase optimization - to keep existing products moving forward. - Mobile app development for iOS and Android - with a focus on stability, performance, and usability. - Full stack developer support - when mobile work needs web, API, or backend coordination. - Native app developer support - when the project needs platform-specific quality and performance. - React Native developer support - for teams already working in JavaScript-based mobile stacks. - Swift developer and iOS developer support - for polished Apple ecosystem apps. - Android developer support with Kotlin - for strong native Android performance. - Flutter developer support - for fast cross platform mobile app delivery. - Xamarin developer support - for legacy apps that need modernization or migration. - .NET MAUI developer support - for teams moving toward a modern Microsoft stack. - Cross platform mobile app delivery - when one codebase needs to support iOS and Android efficiently. I’m a good fit when you need a mobile developer who can think beyond screens and help shape the full product. Whether the goal is a fresh MVP, a native app for iOS or native Android or a cross platform mobile app that can grow over time, I focus on code quality, maintainability, and practical results. I also make sure the work stays aligned with product goals, so the app is not just built well, but built in a way that supports growth and future updates. 🚀 If you need a Flutter developer, React Native developer, Xamarin developer, .NET MAUI developer, Swift developer, iOS developer, Android developer, Kotlin developer, mobile app developer, web developer, MVP development specialist, API integration expert, or full stack developer who can bring structure to a complex build and get it shipped, I’m ready to help.
