# Subham Sarkar on Tal

## Headline

Lead Software Engineer · Backend, Microservices & Cloud\-Native AWS · Building systems that scale at Fidelity

## About

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\.
