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.
