Perfsys is an AWS Select Tier Consulting Partner and authorized AWS reseller helping startups and SMBs build, migrate, and run their businesses on AWS. Founded in 2013 and fully remote since 2022, we've delivered 70+ projects for 30+ international clients across the US, UK, Ireland, Canada, and Europe.
Our AWS Delivery designations in Lambda, Amazon DynamoDB, and Amazon API Gateway reflect verified, hands-on delivery experience — backed by our engineers' individual certifications spanning AWS Certified Solutions Architect (Associate & Professional), AWS Certified Developer, AWS Certified Security – Specialty, and AWS Certified AI Practitioner.
We work across three connected areas: getting companies onto the right AWS architecture, keeping it running well after launch, and solving specialized technical challenges along the way. On the consulting and development side, we handle cloud architecture, application migration, and new product builds on AWS-native infrastructure. Once a system is live, our CloudCare managed services keep it running — support, observability and monitoring, and security and compliance. And for specific technical needs, our solutions cover identity management, AI agents, and data engineering on AWS.
