What I'm looking for

I’m looking for a team where I can own end-to-end frontend features with strong UI/UX collaboration, build scalable design systems, and keep improving through mentoring—ideally with opportunities to touch Node.js/NestJS backend work when it adds value.

I’m a frontend engineer with 5 years of production experience in React and TypeScript, and I take pride in owning the full UI/UX-to-implementation flow—from Figma design and client validation to delivery in code. I work comfortably end-to-end on features, closing the gap between design and development.

At The IT Solutions, I’ve built and maintained SaaS portals for energy sector clients, including customer and reseller dashboards, contract and billing overviews, and internal tools. I’ve also developed complex B2B and B2C e-commerce solutions on Shopify using React and Next.js, including full data migration and custom integrations.

I contribute to a modular design system to keep UI consistent and scalable, using TailwindCSS, HeroUI, and a headless CMS (Strapi). I also mentor junior developers and take on Node.js/NestJS backend tasks when needed, so I can collaborate effectively across the stack.
