What I'm looking for

I'm looking to contribute to international remote teams building scalable web, enterprise, cloud, AI, and data-driven products. I value challenging technical work, collaborative Agile delivery, and opportunities to improve architecture, performance, and user-facing systems.

I've delivered 27+ software projects across healthcare, finance, education, and e-commerce, building enterprise applications that serve thousands of users.

At N-iX Agency, I developed ERP, CRM, CMS, POS, and enterprise web applications using Laravel, React.js, Vue.js, Angular, Next.js, Node.js, Java Spring, MySQL, and Oracle 11g. I integrated payment gateways including PayPal, Flow, Culqi, and Nuvei, while building automated invoicing, tax processing, email notifications, and third-party integrations.

At ELEKS, I built scalable cloud applications and RESTful APIs, managed AWS and Docker environments, and developed AI-powered chatbot solutions using OpenAI and Meta APIs. I focus on reliable architecture, database optimization, testing, and production deployment pipelines.
