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.

Mobile App Development

I develop cross-platform mobile applications using Flutter, ensuring seamless performance on both iOS and Android. While Flutter 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, medical clinics, and news agencies — I offer expert guidance on technology stack selection, IT recruitment, team management, and blockchain-related solutions.

CMS-Based or No-Code

Websites can be built using popular CMS platforms or No-Code / Low-Code solutions. While I primarily focus on custom development, I have extensive knowledge in this area and can help determine if this solution aligns with your needs. I provide guidance on the advantages and limitations of these platforms and can assist in finding the right specialists. Additionally, I can oversee the project and handle QA to ensure a high-quality final product.
