As a Senior Software Engineer with 7+ years of experience, I specialize in building scalable, high-performance applications that deliver seamless user experiences. My focus is modern full-stack development, using React for responsive front-end interfaces and Node.js for efficient, scalable backend systems. I emphasize clean architecture, performance, and maintainability to ensure robust production-ready solutions.
I have hands-on experience designing, developing, and maintaining cloud-native solutions using AWS services, including S3, EC2, RDS, IAM, Systems Manager (SSM), ACM, and CloudFront, ensuring secure, reliable, and cost-effective deployments. Experienced in containerization with Docker and implementing CI/CD pipelines to automate testing, deployment, and infrastructure delivery, enabling faster and more reliable software releases.
As a leader, I have led technical direction, facilitated architecture discussions, and mentored engineers to improve team delivery and engineering standards. I am an effective communicator who collaborates across teams to translate business needs into reliable technical solutions.
I excel at bridging frontend and backend systems, solving complex engineering problems with a structured, analytical approach, and consistently delivering high-quality software that drives business impact and efficiency.
I am passionate about continuous improvement, adopting modern technologies, and building efficient development workflows that enhance both product quality and engineering productivity.
