Web developer with 10+ years of professional experience, successfully freelancing for over seven years. I use Python and Django for most of my work. I have also worked extensively with WordPress in the past, though I rarely do so now. Backend work is my primary focus (API, DB, application logic, CI), but I'm also adept at frontend tasks. When it comes to desktop apps, C# is my language of choice for Windows and Java for cross-platform apps. In all of my projects I put code quality very high on my list of priorities, as well as following standards and best practices. "Readability counts"

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.

I design and build scalable, production-grade systems - not just features. Senior Full-Stack Engineer with experience across high-traffic platforms, I help companies move from idea → reliable, maintainable, and scalable software. Whether it's launching fast or stabilizing complex systems, I focus on architecture, performance, and long-term impact. What I bring: - Clean, scalable backend systems - Modern, performant frontends - System design & cloud-ready infrastructure - Payments, APIs, and integrations that don’t break at scale I’ve built and contributed to: - Distributed systems & migration from monolith to event-driven architecture - Production-grade platforms (e-commerce, booking, search systems) - Performance-critical backend services (load balancing, scheduling) If you need more than just code, someone who can think, design, and deliver, let’s talk.

I'm a developer for AI and webservices with theoretical foundation in AI models (LLMs, classifiers, neural network). I have experience shipping all these models to production, usually taking a few weeks or 1-2 months depending on the applications, from requirements discussions, architecture decisions to testing and deployment. - experience with AI technology, LLMs(GPT, Llama, Mistral, ...) - Python/Java backend development to integrate AI into your architecture - Consulting and review of AI opportunities for customer needs
