Real-time analytics, p99 under 90ms
Pull-request review, eval-gated rollouts
Core Web Vitals tracked from day one

Atlas Trade
We rebuilt Atlas Trade's legacy back-office on a type-safe Next.js + Postgres stack. Tick-to-screen p99 dropped from 540ms to 88ms, and the team retired a $30k/mo vendor in the process.

“We hired Codlinx for an MVP and ended up with a platform we trust enough to run our entire desk on. The team writes code the way our SREs review it.”
Priya Sharma
VP Engineering, Atlas Trade
“They rebuilt our checkout in six weeks and our Core Web Vitals went all green. Conversion followed within a month.”
Liam Foster
CTO, Brightwave Commerce
“The codebase they handed over is the cleanest we've inherited. Onboarding a new engineer takes a day, not a fortnight.”

Engineering Manager, Northwind
FAQ
Common questions about web development.
- Can you take over an existing codebase?
- Yes. We start with a paid two-week audit and return a remediation plan before committing to a build.
- Do you do marketing sites or only apps?
- Both — but only with conversion goals attached. Pretty pages without numbers attached aren't our thing.
- What about SEO?
- Server-rendering, structured data, sitemaps, and Core Web Vitals are part of the default build.
Other services
Most engagements run two or three in parallel.
