Performance & automation practice

Tier-1

Finance & public-sector pedigree

2 weeks

From kickoff to first regression run

Quality assurance, practiced as engineering.

Core practice

Manual & exploratory testing

Structured test plans, risk-based coverage matrices, and exploratory sessions that find the defects scripts never will.

Test automation

Playwright, Selenium, and API suites wired into your CI — deterministic, parallelized, and owned by your team when we leave.

Performance & load

JMeter and k6 models built from real traffic shapes. We report p95s, saturation points, and the fix list — not a PDF of graphs.

Security testing

OWASP-aligned assessments, auth and access-control probing, dependency and secrets review ahead of audit season.

AI-assisted QA automation

LLM-generated test cases from specs and tickets, self-healing selectors, and triage agents that cluster failures before a human opens the report.

Beyond QA, on the same engineering footing.

Secondary services

Web & app development

Full-stack builds and remediation work, shipped against the same test discipline we sell.

How to build a load test from real production traffic

Synthetic 100-user ramps tell you nothing. Deriving arrival rates, think time, and cache-hit ratios from access logs — with a k6 script to match.

Killing flaky tests: a flake budget your team will actually keep

Quarantine lanes, retry accounting, and the CI dashboards that make flakiness a tracked defect class instead of background noise.

AI in QA7 min

Where LLM-generated test cases help — and where they lie

A practical split between spec-to-case generation, self-healing selectors, and failure triage, with the review gates each one needs.

Learn AI the way engineering teams actually use it.

A practical curriculum for software and QA teams: what to learn first, what to skip, and how to evaluate an LLM feature before it reaches production. Written by our founding engineer — no hype, no prompt tricks.

A 6-week self-study path, fundamentals to shipped feature
Eval harness templates for testing AI output like any other system
A QA checklist for AI features: hallucination, latency, cost, and rollback
