Part-Time Contract | Remote | Approximately 20 Hours per Week
About the Role
A mission-critical SaaS platform used by approximately 800 flooring businesses to manage leads, estimates, product selection, inventory, scheduling, installations, invoicing, and paymentsis being modernized from a legacy .NET/ASP, SQL Server, stored-procedure-heavy environment to React, Node.js, TypeScript, native PostgreSQL, REST APIs, and AWS. Much of the initial conversion has been completed using AI-assisted development. The immediate priority is to clean up, test, validate, and safely release the converted system while existing customers remain active.
We are looking for a hands-on Senior DevOps/Platform Engineer who can strengthen the delivery platform, observability, security, and production safeguards required for frequent, low-risk releases.
Responsibilities
- Assess the current AWS infrastructure, CI/CD pipelines, environments, deployment process, and production risks.
- Improve automated build, test, security-scanning, deployment, and rollback workflows.
- Support small,



frequent releases through feature flags, staged rollouts, health checks, and automated validation.
- Establish safe coexistence between legacy and modern services during the migration.
- Build and maintain infrastructure as code for repeatable, auditable environment provisioning.
- Strengthen monitoring, centralized logging, distributed tracing, alerting, dashboards, and incident-response procedures.
- Define service-level indicators for availability, latency, error rates, database health, queues, and critical business workflows.
- Help diagnose performance and stability issues involving AWS, Node.js services, APIs, PostgreSQL, Babelfish, and legacy .NET components.
- Support the transition from Babelfish and SQL Server-oriented behavior to native PostgreSQL.
- Review capacity, connection-pool, timeout, retry, queue, and load-shedding configurations.
- Improve resilience for asynchronous and event-driven workload
