How can we collaborate?

I can deliver a wide range of projects — from simple specific / custom websites to complex full-stack applications with Web3 and AI integrations.

Before selecting a technology stack, I always take the time to analyze your goals, business specifics, budget, and deadlines to find the best-fit solution.

My background includes working with various businesses and projects, not only as a developer but also as an SEO marketer. Additionally, I have hands-on experience in IT team management, which helps me approach projects with both technical and strategic perspectives.

JavaScript Front-End / Full-Stack Development

I build a wide range of web applications, websites, and Web3 DApps using TypeScript, Vue.js, React.js, Next, Nuxt, and Prisma ORM for efficient SQL database management.

2/4

Mobile App Development

I develop cross-platform mobile applications using React Native, ensuring seamless performance on both iOS and Android. While React Native has its pros and cons, it delivers apps that are nearly as fast as native solutions, offering a smooth and efficient user experience.

IT Consulting & Mentoring

With experience across diverse industries — including Yandex (a major tech company), PropellerAds (advertising network), Embria (venture fund and startup incubator), as well as crypto projects, AI startups, medical clinics, and news agencies — I offer expert guidance on technology stack selection, IT recruitment, team management, and blockchain-related solutions.

4/4

AI Automation & Workflow Orchestration

I help businesses find where AI can create real operational value, then design and integrate AI-assisted or agentic workflows for tasks such as customer support, sales operations, reporting, internal tools, and content processes. This includes evaluating the right stack, connecting APIs and business systems, defining guardrails and human review, and shipping practical automations that reduce manual work and improve speed. Whether the solution uses custom code, orchestration platforms, or modern AI tools, I focus on measurable business outcomes rather than AI for its own sake.
