I am a Senior Software Engineer with more than ten years of experience building scalable backend systems, SaaS platforms, travel technology products, finance applications, Human Resource Management systems, and enterprise automation tools. My main skills are in PHP and Python, Node.js, TypeScript, MySQL, PostgreSQL, MongoDB, Redis, Docker, and designing systems that work on the cloud.

What makes me different is that I can take business problems and turn them into simple, reliable, and scalable software solutions. I have worked on systems for selling airline tickets, accounting and finance platforms that use ledgers, Human Resource Management and Enterprise Resource Planning modules, reporting dashboards, and booking systems that are used in businesses.

I am looking for a job where I can work from home as a backend engineer, full-stack engineer, or senior software engineer and contribute to making products, designing systems, creating application programming interfaces, making things work better, and helping with the technical growth of Software Engineering and the company.
