Message

At Now Optics, I develop end-to-end features with TypeScript, React, Next.js, Svelte, and Node.js APIs. I integrated OpenAI APIs into production applications and built visual exam workflows from patient scheduling through medical review and results generation.

Previously, at Binary Solutions, I developed and deployed production platforms and real-time cryptocurrency casino games using native WebSockets. I also worked with asynchronous task systems, message queues, event-driven patterns, and NestJS microservices; at Now Optics, I designed a headless CMS for the Marketing team's content and publishing workflows.
