What I'm looking for

I’m looking for a senior engineering role where I can own scalable React/Node architectures, lead reviews and mentoring, and collaborate with product, design, and QA to ship secure, well-tested features.

I’m a Senior Software Engineer with over 8 years of commercial experience across outsourcing and product companies. I combine B.Sc. and M.Sc. in Computer Science with a practical focus on building maintainable, secure, and performant systems end-to-end.

In my current role at SVITLA SYSTEMS INC., I designed frontend architecture with SSR, a security layer, and a modular component system to keep a growing codebase scalable. On the backend, I built and maintained services using Node.js, Express, and PostgreSQL, and integrated Stripe, AWS, and Elevio to support core business workflows.

I enjoy technical leadership that moves teams forward: mentoring developers, leading code reviews, and driving engineering best practices. I also support reliability through unit testing with Jest and RTL, and I collaborate closely with product owners, designers, and QA to refine requirements and deliver complex flows.

Earlier, at LUXOFT/DXC TECHNOLOGY, I architected a React frontend for a Canadian banking system, including a custom graph-based routing and data-transfer layer, while partnering directly with banking advisors. At CLEARMOVE and Vitamin London, I delivered fullstack and React-focused work across multi-platform apps, APIs, and component libraries—always balancing speed, quality, and clear documentation.
