Tracing & SLO drift
We map p95/p99 curves against your stated SLOs, then tie spikes to specific handlers, queue depths, or missing indexes—not generic “scale up” advice.

Stack Grove Consulting
Project-based programming consulting for teams chasing down slow APIs, database contention, and runaway cloud bills—without rewriting everything on day one.
Where latency hides
Signals we trace before changing code
Each card reflects a layer we profile during assessments: observability gaps, storage bottlenecks, and the human review loop that catches regressions early.
Storage & query plans
Execution plans, lock waits, and ORM N+1 patterns get documented with reproduction steps your engineers can verify in staging.
Implementation pairing
When you retain us for build support, we pair on patches—caching boundaries, batching, back-pressure—so knowledge stays with your team.
We quote each engagement after a written scope: assessment days, advisory blocks, or paired implementation sprints—fees agreed individually, never off a shelf SKU.
Process-led delivery
How a performance engagement runs
Intake & access checklist
You share architecture diagrams, recent incident notes, and read-only telemetry exports. We confirm data-handling boundaries before touching production paths.
Profile & hypothesis log
We capture flame graphs, slow-query logs, and dependency timings, ranking hypotheses by expected latency reduction and implementation risk.
Findings workshop
A structured readout separates quick configuration wins from structural changes—each item lists owner, validation metric, and rollback notes.
Optional build support
If you extend the engagement, we join your sprint ceremonies for targeted PRs; otherwise you receive advisory hours to unblock internal teams.
Heavy-duty systems demand the same discipline online: measure first, change one variable at a time, and keep rollback paths as visible as weld seams on steel.
Questions
FAQ before you book time
Which stacks do you work in?
Typical backends: JVM services, Node/Go APIs, Python workers, and PostgreSQL or MySQL primaries. We focus on performance mechanics—connection pools, serialization, batching—not rebranding your framework.
Do you need production access?
Assessments often start with staging replicas and exported logs. When production access is required, we use least-privilege accounts and document every command in your ticket system.
How are fees structured?
Fixed-fee assessments, day-rate advisory, or paired implementation blocks—each proposed in writing after scoping. No subscription or retainer is implied unless you request one.
Can you guarantee a latency target?
We commit to method and transparency, not marketing guarantees. Every recommendation ties to a metric you already track or one we help you define during intake.
Fit
Who benefits—and who should wait
Good fit: engineering leads with a measurable slowdown, an upcoming traffic event, or a migration where performance sign-off is required.
Not a fit yet: greenfield products without users, or teams seeking a full-time staff augmentation replacement—we stay advisory and project-scoped.
