I build the backend systems that keep enterprise products fast, reliable, and cheap to run. Over 7 years — across Fidelity Investments and Tata Consultancy Services — I've shipped microservices architectures, cloud-native AWS platforms, and CI/CD pipelines that teams actually rely on. A few things I'm proud of: ▸Cut campaign execution timelines by 60% by replacing legacy tools with a unified metadata platform (Micronaut + AWS). ▸Reduced deployment lead time by 30% with end-to-end CI/CD pipelines (Terraform · Jenkins · Kubernetes · ArgoCD). ▸Saved 25% in cloud operational costs by migrating on-prem systems to AWS — and wrote the IaC templates adopted department-wide. My core stack: Java / Spring Boot / Micronaut, AWS (Lambda, SQS, SNS, S3, CloudFormation, OpenSearch), PostgreSQL / DynamoDB / Snowflake, and observability tooling across Datadog, Splunk, and Kibana. I'm a 2× AWS Certified engineer (Solutions Architect + Developer Associate) and a SnowPro Core holder. I've also been going deep on data engineering and ML pipelines — because the line between backend and AI infrastructure keeps blurring. I'm drawn to roles where the engineering problem is genuinely hard — high concurrency, complex integrations, or systems that need to survive scale. If you're building something in that space, I'd love to hear about it.
