Monzer Hossain has more than thirteen years of software engineering experience which includes requirement collection & analysis, solution design, application development and deployment & maintenance of the developed applications by ensuring required enhancement and bug fixing. He is keen to solve complex backend problems in collaboration with fellow engineers and stakeholders and also love to guide juninor engineers to excel in their careers.

He started his career in a system/software engineer role in a leading telecommunication operator, Grameenphone Limited (Affiliate of Telenor, Norway), in Bangladesh. During his eight years career he involved in different phases of Software Development Life Cycle (SDLC) from requirement analysis and design to development of several network performance, fault, configuration and inventory management systems. He had the opportunity to work with different development technologies such as Java/J2EE, C++, C#, HTML, PHP, JavaScript, CSS and several database management systems such as Oracle, MySQL. He has working experience of several scripting languages such as shell, Perl etc. in Unix based environments. He deployed and administered Apache Tomcat, JBoss, Weblogic and IIS web servers to host enterprise grade applications.

In order to hone his knowledge and skills, later he opted for further study and completed MS in Computer Science from Computer Science and Engineering Department of University of California, Riverside in March 2016. He also worked as Graduate Student Researcher (GSR) in Networks, Systems and Security Laboratories. His project involved security issues in Software Defined Networks (SDN). He also learned several machine learning and data mining techniques as well as big data processing using Hadoop’s map-reduce framework in order to bulid search engine in his course works and projects. He also studied several data center network topologies, cloud computing, network function virtualization, software defined networking etc. extensively.

After finishing his MS, he briefly worked in a VOIP network monitoring software development company in California and then moved to Sydney. Then he worked in the IT department of a retail company as Software Engineer. He was involved in designing, developing and customizing warehouse management systems, freight management systems, e-commerce systems etc. using different PHP frameworks such as Symfony, Magento. He also developed few in-house tools using Java, NodeJS, Serverless framework etc. to facilitate day-to-day operations of the company. He worked in different AWS such as Lambda, DynamoDB, SQS, SES, RDS, S3, CloudWatch etc. He integrated different systems through REST API, messaging service (SQS). He used Atlassian stack (Bitbucket, Jira, Confluence etc.) and scrum methodology for project management.

Currently he is working in the Platform Engineering squad of a global SasS company as Senior Software Engineer. He is involved in design, development, deployment and maintenance of various microservices to support the core platform of the product. He actively participates in the planning and design phase of many mission critical initiatives and drives those projects to successful completion by both contributing himself and enabling fellow team mates to excellence through mentoring, sharing ideas, enforcing best practices, code reviews etc. He has contributed to various complex systems including backstage service, notification service, query service, document management system, employee onboarding etc. The technology used for those projects were PHP, Golang, AWS ECS, ECR, SQS, Mysql (Aurora), DynamoDB, Lambda, Appsync, EC2, S3, DMS, Redshift, Kinesis, Docker, Jenkins, Terraform, Coudwatch, Datadog, Localstack etc. He is also responsible for analyzing and optimizing performance of the product through various initiatives.
