I build production-ready mobile apps for Android & iOS from a single codebase using Kotlin Multiplatform helping startups launch faster, reduce costs, and scale confidently. With 6+ years of experience, I don’t just write code I deliver complete, stable, and scalable applications that are ready for real users. I’ve worked on live applications published on Google Play and specialize in building apps that are: ✔ Fast and responsive ✔ Secure and well-architected ✔ Designed for long-term scalability 💡 What I Can Do For You Mobile App Development (Primary Focus) Build Android + iOS apps using Kotlin Compose Multiplatform Share business logic across platforms → reduce development cost Clean architecture, scalable codebase, production-ready systems App performance optimization and stability improvements Backend & Full-Stack Development Build APIs using Ktor (Kotlin) Authentication systems (JWT, sessions, secure flows) Database design (PostgreSQL / SQL) Media handling (uploads, streaming, cloud storage) Google Play Expertise (Big Advantage) Publish apps to Google Play (end-to-end) Fix Play Store policy issues & rejections Optimize listings for better conversions Setup verified organization accounts 🚀 Results Clients Care About Faster development using shared codebase Reduced cost (one codebase instead of two teams) Stable apps that don’t break in production Clean UI + smooth performance Proper backend structure (no messy systems) 🧠 Why Clients Choose Me I’m not just a developer, I think like a product builder. With a background in Biomedical Engineering (FUTO), I bring: Precision and attention to detail Structured problem-solving Strong focus on reliability and risk management Plus, I have experience in: Startup environments (fast execution, real impact) Project management (clear timelines & delivery) Product thinking (building what users actually need) 🛠 Tech Stack Mobile: Kotlin, Compose Multiplatform (Android, iOS, Web, Desktop) Backend: Ktor, PHP, REST APIs Frontend: JavaScript Database: PostgreSQL, SQL 🤝 How I Work Clear communication from day one Defined milestones and timelines Regular updates and progress tracking Long-term support if needed I treat every project like a partnership — your success is my priority. 📩 Let’s Work Together If you’re building a mobile app and want: One codebase for Android & iOS A clean, scalable backend A developer who understands both tech and business Send me a message — let’s discuss your project.
