Hire Event Sourcing Experts | Nearshore Software Development

Event Sourcing is a powerful architectural pattern that captures all changes to an application state as a sequence of events. Instead of storing just the current state, you store the full history of events that led to that state. You need an expert who can leverage this pattern to build a system that is auditable, scalable, and can provide rich insights into your business. Our vetting process, powered by Axiom Cortex™, finds engineers who are masters of event-driven architecture. We test their ability to design an event-sourced system, to handle the challenges of eventual consistency, and to build powerful projections of the event stream.

Are you losing valuable historical data about your business?

The Problem

Traditional, state-oriented systems overwrite data, losing the rich history of what happened and why. This makes it impossible to answer important business questions about the past.

The TeamStation AI Solution

We vet for engineers who are experts in building systems that capture every change as an immutable event. They must demonstrate the ability to use an event store to create a complete and auditable log of everything that has ever happened in the system.

Proof: Complete Audit Trail and Rich Historical Insights
Is your system struggling to scale and evolve?

The Problem

A monolithic, state-oriented system can be difficult to scale and to adapt to new business requirements.

The TeamStation AI Solution

Our engineers are proficient in designing scalable and flexible event-sourced systems. They are vetted on their ability to use patterns like CQRS to create multiple, independent projections of the event stream, enabling you to scale your read and write workloads independently and to easily add new views of your data.

Proof: Scalable, Flexible, and Evolvable Architecture
Is debugging production issues a nightmare?

The Problem

When you only have the current state, it can be nearly impossible to reconstruct the sequence of events that led to a bug or data corruption. Debugging becomes a process of guesswork.

The TeamStation AI Solution

Our experts understand that an event log is the ultimate debugging tool. We vet their ability to use the event stream to replay history, debug complex issues, and understand exactly how the system arrived at its current state, dramatically reducing time-to-resolution for production incidents.

Proof: Rapid debugging and incident response via event replay
Are you unable to gain new insights from your existing data?

The Problem

Your current data model was designed to answer a specific set of questions. When new business requirements emerge, it's often difficult or impossible to answer them without a costly and complex data migration.

The TeamStation AI Solution

We hire engineers who see the event stream as a source of infinite potential. They are experts at building new projections from the existing event log to answer new business questions, without ever having to change the way data is written. This provides incredible business agility.

Proof: Business agility through on-demand data projections

How We Measure Seniority: From L1 to L4 Certified Expert

We don't just match keywords; we measure cognitive ability.

Our Technical Analysis for Event Sourcing

The Event Sourcing evaluation is a deep dive into advanced distributed systems design. Candidates are required to design an event-sourced system for a complex domain, demonstrating their understanding of aggregates, domain events, and commands. A critical assessment is their ability to design a solution for handling eventual consistency and to build projections for different read models. We also test their knowledge of different event store technologies. Finally, we assess their experience in operating and evolving an event-sourced system in production.
