Crafting Scalable Solutions

A glimpse into who I am and what drives me.

I'm a Software Architect with 16+ years of experience designing and building scalable applications across cloud, messaging, performance testing and automation domains.

My core stack revolves around Java, AWS and Clean Architecture principles. I believe great software solves real problems elegantly — and I bring that mindset to every project, from open-source libraries to enterprise cloud solutions.

As an AWS Community Builder, I actively share knowledge through technical articles, community events, and open-source contributions that help teams build better, more resilient systems on the cloud.

Cloud Architecture
Designing resilient, cost-optimised AWS solutions with serverless and container-based workloads.
Messaging & Streaming
Building event-driven systems with Kafka, AWS Kinesis, SQS, SNS and IBM MQ.
Performance Testing
Creating JMeter plugins (awsmeter, mqmeter) that enable load testing at scale on cloud services.
Open Source Lover
Contributing back to the community with libraries, demos and technical writing.
