Software engineer with 9+ years of experience in frontend and backend development, specializing in React, Next.js, and Node.js. I build complex web applications end to end, from user interfaces and real-time interactions to backend services, APIs, and application architecture.

On the backend, I work with Node.js and Express.js, developing APIs, implementing business logic, and integrating services. My experience includes data-intensive financial and trading applications, WebSocket-driven market data, and custom TradingView integrations, where performance and efficient communication between the client and server are critical.

I design application architectures from scratch and evolve existing systems as products grow. I’ve worked with Domain-Driven Design, Clean Architecture, and Feature-Sliced Design to establish clear boundaries and keep large codebases maintainable. I also investigate production issues and optimize performance across the stack, from rendering, SSR, and data fetching to request volume and backend load.

I take an active interest in the product behind the code: understanding user needs, questioning requirements, discussing UX, and using product metrics to inform technical decisions. I continuously explore new technologies, including AI tools and integrations, and look for practical ways to apply them to development workflows and product features.

I also have leadership experience and am comfortable taking responsibility for technical direction and coordinating team delivery while staying hands-on with development. Having worked in small startups and organizations with 50+ developers, I’m open to senior engineering, tech lead, and team lead roles that combine technical ownership, product involvement, and building software.
