What I'm looking for

I’m looking for a team where I can build maintainable full-stack products, own scalable APIs and frontend experiences, and collaborate in Agile to solve business-critical problems with TypeScript and modern frameworks.

I’m a Full Stack Software Engineer with 5 years of experience building web and mobile applications across consulting, financial services, energy, and marketing technology industries. I develop scalable solutions in TypeScript and JavaScript, delivering maintainable software that solves complex business problems through technology. I also enjoy working in Agile environments with cross-functional teams to ship reliable frontend experiences and backend services.

I’ve built and maintained full-stack features across internal platforms, designing REST APIs and business logic with NestJS, TypeORM, and MySQL to support business-critical workflows and integrations. I’ve also supported marketing automation and event management, implemented integrations for cross-platform operations, and delivered frontend modules with React/Next.js and Vue/Nuxt—contributing to shared UI consistency via Storybook. From mobile banking interfaces to WordPress web solutions, I focus on high-quality user experiences and dependable delivery end to end.
