Design service-oriented backend systems for products that need cleaner scaling paths and better service boundaries. We help teams break down monoliths, define communication patterns, and reduce operational complexity as platforms grow.

Database Architecture & Optimization

Build database layers that support performance, consistency, and long-term maintainability. We design schemas, indexing strategies, and query patterns that help products stay responsive under increasing load.

Upgrade outdated backend systems without disrupting business-critical workflows. We help teams modernize architecture, reduce technical debt, and improve long-term maintainability through phased engineering plans.

Real-Time Processing

Support products that rely on live updates, event-driven workflows, and streaming data. We build backend systems that can process and deliver real-time information reliably across customer-facing and internal use cases.

Monitoring & Observability

Create stronger production visibility across backend systems and infrastructure. We help teams instrument services, surface useful alerts, and improve response speed when performance or reliability issues appear.

"I was concerned about a possible mismatch of talent levels of our in-house engineers versus contractors. But, as it turns out, many of the Seven Unique engineers we hired emerged as top performers. In fact, of our group of 120 developers, all the Seven Unique engineers we had were in the top 20 of the organization.
