About Tenlyr

We're interested in what happens underneath the product.

Tenlyr is a product engineering studio built around a simple idea: Good engineering isn't about predicting everything. It's about making the right decisions as the product changes.

Why Tenlyr exists ↓

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 an entire week. Deployments become tense events. The team knows something is wrong with the backend, but nobody has the dedicated bandwidth to stop feature work and isolate it.

That's the kind of problem we like solving.

Tenlyr doesn't exist to sell billable hours or build generic brochure websites. We exist to be the specialist engineering brain in the room when product growth starts testing the limits of your architecture.

Founder & Architect

Direct engineering partnership.

Rajesh Ayyavu Founder · SaaS Architect · Tenlyr

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

Not just how a feature works in a local staging environment when everything goes right. But:

• What happens when 10,000 concurrent users execute the same workflow?
• What happens when the relational database grows past 50 million rows?
• What happens when an AI pipeline starts generating $8,000 monthly API invoices?
• What happens when the product changes faster than the original architecture assumptions?

Those questions are where I spend most of my time. No sales team. No account managers. Just a direct technical conversation about what you're building and where it's starting to hurt.

Architectural principles

Our engineering beliefs.

Clear constraints that guide every technical 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.
