Mahmoud Samir

I’m a Senior Software Engineer and former Technical Lead with 7+ years of software development experience, specializing in Java, Spring Boot, REST APIs, and distributed microservices. I build reliable backend systems, improve application performance, and help teams deliver maintainable software through practical architecture, code reviews, and mentoring. At Vodafone, I automated CI/CD pipelines with Jenkins, reducing deployment times by 70%. I also built a fault-tolerant RabbitMQ cluster capable of processing 80 million messages daily, supporting high-volume business applications. Currently, I work at IMTAC in Oman, leading full-stack development for an education digital transformation project. My work includes automating school evaluation, inspection, and appeal workflows using Spring Boot, Angular, and Camunda, alongside system architecture and deployment automation. My technical toolkit includes PostgreSQL, Oracle, MongoDB, Docker, Jenkins, Redis, and Hazelcast, with a strong focus on testing, messaging, and database performance. I’m looking for a fully remote Senior Backend Engineer or Technical Lead role where I can own backend services, solve scalability and reliability challenges, and collaborate with a team that values clear communication and engineering quality. I’m open to both full-time roles and contract opportunities.
