What I'm looking for

I want to build reliable full-stack web products where I connect UI flows with backend logic—especially real-time systems, integrations (payments/auth), cloud deployment, and practical AI features.

I’m a Full-stack Developer with 4+ years of commercial experience building modern web products with React, Angular, Node.js, NestJS, TypeScript, and PostgreSQL. I’ve worked across SaaS, creator tools, marketplaces, mobile, and real-time products—connecting frontend flows to backend business logic and turning product ideas into stable features.

I’m especially strong at end-to-end integration: API work, authentication, payments, WebSockets, caching, and cloud deployment. In recent roles, I implemented YouTube channel connection and uploading flows, built Stripe/Stripe Connect payment logic for creator earnings and payouts, and integrated OpenAI API features for AI-assisted workflows.

I also enjoy working with existing systems and complex domains, whether it’s syncing data from Salesforce, building price-list and real-time monitoring systems, or developing gameplay and multiplayer features. My professional focus is clear architecture, reliable delivery, and building product experiences that perform well in production.
