For 15+ years, I’ve built web and mobile apps that run reliably in production — not just demos. Clients come to me when systems need to stay stable under load and behave predictably. I focus on architecture and delivery that actually work in real conditions. I’ve delivered 100+ projects, including high-load systems with millions of users. My experience covers VPN & cybersecurity solutions, banking software, AI tools, real-time tracking systems, and scalable mobile/web platforms with complex functionality — along with other non-trivial systems. Tech: • Swift (UIKit / SwiftUI), Kotlin (Jetpack, Coroutines) • React (Next.js), Vue • Node.js (NestJS / Express), PHP (Laravel / Yii2) • WebSockets, TCP/UDP • REST / GraphQL APIs • Stripe / PayPal • Firebase, Amplitude, AppsFlyer, RevenueCat • OpenAI, Gemini, Claude, vector DBs • JWT, OAuth2, encryption, secure storage I handle architecture and key decisions myself. If needed, I involve additional developers — always transparently. Process is straightforward: define scope → plan → build → test → release → support. No overengineering, no surprises. If you need help with a new project or improving an existing one — send a short description, and I’ll quickly outline the best way to approach it.
