Specializing in AWS Serverless Development, DevOps Automation, and Safety-Critical Software Verification (DO-178B/C).
Welcome to Cloud Services LLC. I am Sridhar Renangi, an IT professional with over 5 years of experience across two demanding disciplines — enterprise AWS cloud engineering and safety-critical avionics software verification.
Currently based in Hillsboro, OR, I work as a Software Developer at Keypixel IT Solutions, where I architect and deliver cloud-native systems on AWS — cutting manual analysis time by 40% through Lambda-driven data pipelines, and improving security compliance by 15% through IAM least-privilege enforcement and VPC PrivateLink isolation.
Prior to that, I served as an AWS Developer at Arizona State University, where I designed serverless architectures that reduced operational overhead by 20% and improved application response times by 30% — all built on Lambda, API Gateway, Step Functions, and RDS.
My foundation was built at Tata Consultancy Services, where I spent three years performing Hardware-Software Integration (HSI) testing for the Rolls-Royce Trent XWB and Trent 1000 engine control systems — validating safety-critical avionics software under DO-178B/C Level A compliance using MC/DC coverage techniques. That experience instilled an engineering discipline that I bring to every cloud system I design today.
I hold a Master of Science in Information Technology from Arizona State University and a B.Tech in Electronics and Communication Engineering. I build infrastructure that is not just scalable — it is engineering-grade reliable.
End-to-end serverless architectures using AWS Lambda, API Gateway, and Step Functions. Designing modular VPCs that mirror complex production environments.
Infrastructure as Code provisioning with Terraform and CloudFormation. Building CI/CD pipelines (Jenkins, AWS CodePipeline) to accelerate release cycles.
Implementation of IAM least-privilege policies, Secrets Manager, and audit logging via CloudTrail to meet enterprise data privacy standards.
Specialized verification for safety-critical software (DO-178B/C), including MC/DC analysis, Hardware-Software Integration (HSI), and fault injection testing.
High-throughput telemetry ingestion using DynamoDB and Python (Boto3). Schema migration and RDS query optimization for sub-millisecond latency.
Full-stack monitoring setups using CloudWatch, Grafana, and ELK Stack to detect errors in real-time and reduce incident response times.
