About Tenlyr

We're interested in what happens underneath the product.

Tenlyr is a small team built around a simple idea. Good engineering is not about predicting everything. It is about making the right choices as the product changes.

Origin

Most technical problems don't start as technical problems.

A founder wants to ship faster.

An engineer adds a quick workaround to meet the deadline.

The feature becomes popular. Usage grows.

Another workaround gets added on top of the first one.

Six months later, something that used to take a day takes a week. Releases feel tense. The team knows something is wrong behind the scenes, but nobody has time to stop and find it.

That's the kind of problem we like solving.

Tenlyr doesn't exist to sell hours or build brochure websites. We are the specialist in the room when your product's growth starts to strain how it was built.

Founder & Architect

Direct engineering partnership.

Rajesh Ayyavu Founder · Software Architect · Tenlyr

I started Tenlyr because I enjoy understanding how products behave underneath the surface.

Not just how a feature works when everything goes right. But:

• What happens when 10,000 people use the same feature at the same moment?
• What happens when your database grows to tens of millions of records?
• What happens when an AI feature starts costing thousands of dollars a month?
• What happens when the product changes faster than the original plan expected?

I spend most of my time on those questions. No sales team. No account managers. Just a straight conversation about what you are building and where it hurts.

Architectural principles

What we believe.

Simple rules that guide every decision we make.

01 We don't optimize what doesn't matter.

02 We don't rebuild things just because they're old.

03 We don't add complexity without a measurable reason.

04 We don't confuse architecture diagrams with working production systems.

05 We don't stop at recommendations when implementation is the real problem.

Track record
