I’m a Senior Software Engineer with 5+ years of experience building production web applications across SaaS, payments, transactional systems, and API integrations. I work mainly full stack, with a strong focus on React and TypeScript for the frontend, and Node.js/PHP (Laravel) for the backend—always aiming for pragmatic, reliable solutions that keep working well beyond the happy path. I’ve also worked as a Full Stack consultant across multiple domains like banking/financial services, security, medical, and enterprise systems. My day-to-day challenges often involve checkout flows, webhooks, payment provider integrations, reliability, and state consistency, and I enjoy designing maintainable architectures, clean interfaces, and dependable integrations that scale.
