What I'm looking for

I am seeking remote roles where I can architect scalable, real-time systems, lead technical delivery, and work with modern stacks (React/Next.js, Node.js, Python, AWS) while collaborating in Agile teams and improving observability and CI/CD.

I am a Senior Full-Stack Developer with 6+ years building scalable, secure applications using React, Next.js, Node.js, TypeScript, PostgreSQL, and AWS.

I specialize in designing production-ready systems, real-time applications, and developer tools, and have architected solutions that reduced data latency to under a second and cut sync times by 95%.

My work includes rebuilding a multi-tenant CMS that achieved 70% infrastructure savings, modernizing logistics and inventory systems, and automating ETL and deployment pipelines to improve reliability and speed.

I follow Agile practices, implement CI/CD with Docker and GitHub Actions, and emphasize testing (PyTest, Jest, Cypress) and observability to deliver high-availability, performant products.
