# Masoom S. > Staff Software Engineer, Staff Platform Engineer | Java, Spring, AWS, Kafka, Docker, GitLab CI/CD | Observability Wizard Location: San Jose, California, United States Profile: https://flows.cv/masoom When I'm not building Enterprise Software at Scale transacting billions dollar daily, I’m probably tweaking Splunk/Datadog dashboards — or explaining to friends why blue-green isn’t just a color combo. I’m a Staff Platform Engineer with over 15+ years of experience in platform engineering. I’ve spent many years in the design / build / ship / iterate software lifecycle both hands on and in leadership roles, at companies of all sizes from startups to enterprise organizations such as Bill.com and Gap. I believe the key to making rock solid products is for platform engineering teams to be customer obsessed and capable of rapidly iterating using lean principles to ensure stable and scalable infrastructure. ACCOMPLISHMENTS at BILL: - Led migration of mainapp from on-prem infrastructure to AWS (EC2, Fargate, Lambda, S3, RDS, CFT), Docker, Java, and Gitlab CI/CD, reducing infrastructure costs by 30% and increasing system availability to 99.99%. - Modernization of deployment process for legacy apps by re-building release pipelines utilizing Java AWS, Oracle and Gitlab CI/CD, integrating automated testing, and orchestrating phased rollouts, transformed 7+ hours downtime releases into zero-downtime deployments and boosting operational efficiency. at Prosper: - Designed and implemented scalable, highly available, and secure RESTful API microservices using Java and Spring Boot, developing intelligent traffic distribution algorithms among credit unions which increased loan origination by over 10%. - Collaborated with DevOps team to build robust CI/CD pipelines, configure Docker and Kubernetes environments, and define standardized GitHub branch strategy, significantly expediting release cycle time by 10X. at Gap: - Developed RESTful API microservices in Java, Spring Boot and Kafka to fetch customer credit data from MongoDB and transmit it to Synchrony Financial for credit limit increases and pre-approvals, generating $2M in ARR.
