AWS Cloud Case Studies — Real Client Results

"Perfsys's knowledge about technology and understanding of our needs and services have been impressive. Perfsys turned our deployments from hands-on AWS work into reviewed, automated pipelines, and onboarding a new client environment now takes about half a day. Their project management has been perfect, and they have delivered in every weekly meeting."

Chief Application Architect, Nogalis Inc

"What impressed me most was Perfsys' personal approach. As a startup, we needed a knowledgeable team that was accessible and responsive, and Perfsys struck that balance perfectly, with direct access to the people doing the work. They delivered a production-ready OlivPay on schedule and within budget, and as a non-technical founder I especially appreciated their guidance."

"What stood out most about Perfsys was their genuine depth of experience in government and financial technology. They came in with relevant background and understood the complexity of what we were building from day one, and the team was enthusiastic and committed throughout. Perfsys completed all nine planned milestones of the phase, delivering a working three-portal system with a no-code workflow configuration engine."

"Perfsys' dedication to getting the job done and done correctly was impressive. They helped us do exactly what we had been trying to accomplish for almost a year with several other companies, reviewing our entire AWS account and backing up all of our data for transfer to a hard disk. They took care of my needs immediately, I never had to follow up, and I would highly recommend them."

Jazmin Sarabia

Office Manager, Aztec Data Supply, Inc.

"On a scale of five stars, we give them a six! What impressed me most about Perfsys was the team's domain expertise: AWS cloud software is complex, and after three different sets of full-stack developers failed to integrate our AWS analytics over six months, Perfsys succeeded. They fixed all our analytics issues and restored KaZang's data flow across four AWS services, so we call them the "Dream Team.""

Gary Matsumoto

Founder & CEO, KaZang, Inc.

"We've been most impressed with Perfsys' responsiveness and expertise. They have been helping us configure our AWS VPCs and manage updates so they work securely across development and production, and we have seen real improvements. Perfsys delivers on time and responds well to our needs, and we chose them for their good reviews, cost-effectiveness and ease of doing business."

"The knowledge Perfsys had about working with serverless solutions from AWS was impressive, and together with fast development and quick responses in communication, it made them a perfect partner. They built our digital signage platform, which now runs 24/7 and is used daily, and our monthly costs are lower than ever thanks to the serverless approach we chose together. Perfsys always answered directly and solved issues fast, so we now have a stable solution that we can trust."

Andreas Sallmunds

Founder, Roligt AB

"They were very responsive and devoted to their work. Perfsys planned, created and now maintains our cloud environment, and we have working, stable production and other environments. The work has always been delivered on time."

"The workflow with Perfsys was tightly integrated with how we like to operate, with everything communicated through Slack and code commits and build status updates automatically notifying our engineering team. Perfsys took on provisioning our AWS resources and finishing our CI/CD workflow, which let our engineers focus on core business decisions. I was especially impressed by their communication and willingness to teach and transfer knowledge, which left us in a great place to continue maintenance on our own."

Thomas Reid

Engineering, Startup

"Perfsys is proactive and has creative ideas on how to approach the very unique setup we have in our company, almost always finding professional and effective solutions. They migrated our production environment to AWS and built a custom Keycloak-based SSO solution, and our web app and SSO now run exactly the way they should. Having the same agile mindset on projects made the communication and workflow with the Perfsys team outstanding from the beginning."

Ingmar Bornholz

CEO, my-vpa GmbH

"I have a very high level of confidence with Perfsys. I can go to bed at night knowing I won't wake up to a user complaint about website or login errors, something we experienced weekly with a previous agency, and their maintenance package comes with built-in alerts. It also costs less than the retainer we paid that agency, while Perfsys keeps us aligned on industry best practices."

Alexey Scherbakov

CTO, Intro Inc.

"Perfsys took great pride in the quality of their work. Their ability to meet a deadline and implement complex solutions with little rework is remarkable. They delivered full-stack development of our scalable, easy-to-configure product and deployed it to production, which helped us win new business."
