StackVertex Consulting
When APIs multiply and deployment pipelines crack, you need an architect who writes code—not slideware. We take on discrete cloud application architecture engagements with scope and fees agreed before work starts.

Where cloud designs stall
Teams inherit microservices that never quite decompose, identity flows that sprawl across regions, and Terraform stacks nobody wants to touch. The symptoms look like slow releases and noisy incident pages—not a missing slide in a deck.
We focus on programming consulting for cloud application architecture: service boundaries, event contracts, runtime topology, and the code paths that keep them honest.
Project-based, not a retainer shelf
Each engagement is scoped as a project. Deliverables, milestones, and fees are written down and signed off before implementation consulting begins.
Typical architecture threads
Container orchestration choices, API gateway placement, multi-account AWS or Azure landing zones, queue-backed workers, and observability hooks that match how your team actually deploys.
Read-heavy systems
Cache tiers, read replicas, and CQRS-shaped boundaries when traffic spikes are predictable but schema churn is not.
Integration seams
Partner APIs, webhook reliability, idempotency keys, and schema versioning when you cannot pause the business for a big bang migration.
Security-minded defaults
Least-privilege IAM, secret rotation patterns, and network segmentation that developers can live with during daily deploys.
Architecture decisions should survive the next hire
Problem-led reviews start with the failure you are trying to prevent: cascading outages, runaway cloud bills, or a release train that only moves on Fridays. We map the runtime graph, read the repos that matter, and propose structural changes you can implement incrementally.
Documentation is code-adjacent—sequence diagrams tied to real endpoints, ADRs with rejected options spelled out, and migration steps sized for your team’s capacity.

Cloud application architecture is not a logo on a landing page—it is the set of constraints your compilers, containers, and on-call rotations all agree on.
From notebook to production graph
We pair whiteboard-level reasoning with the repositories that implement it. That means reading your service templates, tracing a critical user journey through queues and databases, and pointing to the exact modules that need refactors—not generic “best practices.”

Cable management is a metaphor—and a metric
Tangled dependencies show up in network paths and in import graphs. We document both, then sequence removals so you can ship fixes while traffic is live.

Questions teams ask before signing a scope
Do you resell cloud credits or software?
No. Fees cover architecture consulting and hands-on programming guidance. You keep direct relationships with your cloud vendors.
Can you embed with our developers?
Yes, when the scope includes pairing sessions or review gates. We still document decisions so knowledge stays when the engagement ends.
What languages and stacks?
We work where your services already live—commonly TypeScript, Go, Python, and JVM stacks on Kubernetes or managed container platforms.
How do fees work?
We quote project fees after a discovery call. There are no published package prices on this site; each statement of work is individual.
