AI Overview
Performance snapshot
Perfsys is a cloud-focused software and DevOps consultancy with a consistent track record across AWS infrastructure, CI/CD pipelines, custom software development, and AI integration. The vendor's ratings skew overwhelmingly positive across all five evaluation categories, with strong evidence of on-time delivery, technical depth, and responsive client engagement. No recurring negative trends or declining scores were identified. The sole area of minor concern is a single below-average cost rating in one older review, which is isolated and does not represent a pattern.

Processes and approach
How do you gather and validate client requirements?
We run workshops, ask targeted questions, and review current systems. Requirements are captured as user stories and validated through early prototypes and feedback loops. This ensures clarity before development starts.
How do you ensure alignment with client goals and business strategy?
We map every feature to a business goal and review priorities with stakeholders during planning. Our iterative delivery model ensures the solution evolves with your strategy.
Which software development methodologies do you use (e.g., Agile, Waterfall, Scrum)?
We mainly use Agile with Scrum 2-week sprints, daily standups, and sprint reviews. This keeps development transparent and allows rapid feedback. Waterfall is used only for fixed-scope compliance projects.
How do you keep clients and stakeholders updated on project progress?
We use weekly or biweekly demo calls, shared dashboards (Jira, Notion), and async updates in Slack or email. Stakeholders can track deliverables, timelines, and blockers in real time.
How frequently do you hold check-in meetings or status updates?
We do weekly or biweekly check-ins depending on project pace. Urgent or high-priority tasks can trigger ad-hoc syncs. Slack or Jira is used for daily async updates.
What quality assurance practices do you follow?
We use automated testing (unit, integration, e2e), manual QA, code reviews, and CI pipelines. Each change is tested in staging before production. QA is involved from day one.
How do you identify and manage project risks?
Risks are reviewed during planning and each sprint. We manage them through architecture reviews, backlog grooming, testing, and frequent client syncs. Critical risks are escalated fast.
What kind of support or maintenance do you offer after delivery?
We offer tiered AWS support packages—basic to 24/7 with SLAs. Includes monitoring, backups, incident response, cost audits, and hands-on fixes. Custom support is available too.
