What I'm looking for

I am seeking senior backend or full-stack roles where I can design scalable microservices, integrate AI/third-party APIs, work in Agile teams, and drive CI/CD and performance optimizations.

I am a Full Stack Software Engineer with nine years of experience building and deploying web applications, primarily focused on backend development using Node.js and TypeScript.

I have designed and implemented microservices architectures, RESTful and GraphQL APIs, and serverless functions, and I have integrated payment gateways and third-party services across Fintech, e-commerce, logistics, event management, and SaaS domains.

On the frontend I build responsive SPAs and reusable UI components with React, Redux and Angular, and I optimize performance using profiling tools and modern UI libraries like Material UI and Tailwind CSS.

I work effectively in Agile teams, employ CI/CD pipelines and container orchestration with Docker and Kubernetes, and emphasize test coverage and secure integrations using JWT and OAuth2.0.
