Senior Software Engineer · Cloud · Full Stack
I’m Abraham Rohith Roy, a Senior Software Engineer with 14+ years of experience in full-stack development and cloud engineering on AWS and Azure. I design and ship reliable, maintainable enterprise applications.
Senior Software Engineer at Cognizant with a career in enterprise software engineering since 2013, and a strong focus on cloud platforms and scalable application design. I care about clean architecture, developer productivity, and delivering software that lasts.
Full-stack enterprise engineering, serverless architecture on AWS and Azure, RESTful API design and management with Apigee, strong data analysis and data management across SQL and NoSQL databases (MongoDB, DynamoDB), and observability with Splunk and Datadog.
I pair hands-on engineering with continuous learning, applying cloud-native patterns and modern development tooling to build maintainable solutions and accelerate delivery.
Clean engineering, continuous improvement, pragmatic problem solving, collaboration, and shipping reliable software with confidence.
Areas of professional work reflected in my software engineering experience, with the core tools and technologies used in each.
Developed and supported full-stack enterprise applications across a long-term career at Cognizant, focused on scalable, maintainable software.
Designed and operated serverless architectures on AWS and Azure — event-driven, auto-scaling workloads built with Lambda, Azure Functions, and managed cloud services for scalability, security, and cost efficiency.
Designed and delivered RESTful APIs that power enterprise workflows, managed and secured through Apigee and instrumented with Splunk and Datadog for monitoring, alerting, and reliability.
Strong data analysis and data management across relational and NoSQL stores — modeling, querying, and optimizing data with SQL, MongoDB, Amazon DynamoDB, and Elasticsearch to drive reliable, data-informed decisions.
