Clear Stack.
Senior product engineers · San Ramon · Bengaluru
Senior engineers, a stable team, and applications built to be kept.

A small studio of senior product engineers. Ruby on Rails specialty. We build and operate business-critical applications, often for the better part of a decade.

§ I · What we do

Three things, done well.

We're more useful when we're honest about scope. Below is the entire menu — nothing else is on it.

i. Build

We design, build, and ship modern web applications.

End-to-end. Specialty: Ruby on Rails. Surrounding stack: Hotwire, Tailwind, Postgres, TypeScript where it earns its keep.

Rails Hotwire Tailwind Postgres TypeScript
ii. Operate

We run applications already in production.

Proactive monitoring, on-call, SLAs we keep, and parallel feature capacity. Most of our long-term client relationships started here.

Monitoring On-call SLAs Parallel dev
iii. Migrate & Automate

We move applications to the cloud, and automate how they live there.

Cloud migrations to AWS and Azure. Infrastructure-as-code with Terraform, Ansible, and Packer. We've operated cloud deployments for clients for eight years and counting.

§ II · How we work

Four beats, on every project.

Small commits. Continuous deploys. Decisions on production behavior, not a slide.

01 Frame
The problem in a sentence

A shared problem statement. The metric that defines success. What's out of scope, in writing. Estimates as cost ranges, not promises.

02 Slice
The riskiest thing, first

A useful production path in the first week behind a feature flag — exercised by real users or real-shaped data. We learn from a running system, not a deck.

03 Ship
Small commits, continuous deploys

Deploys are routine. Tests and feature flags carry the safety. Code review is for taste and architecture, not gating.

04 Hold
Evidence before opinion

Observability is the source of truth. We add to the system based on what it does in production, not what we hoped it would do.

§ III · A representative engagement
"ClearStack was able to succeed where other companies failed by delivering on time, and with consistent quality."
Graeme Queen Director of IT Services, The Standard

We introduced Ruby on Rails to The Standard's engineering team and trained them on it. Together we built the data-intake and processing engine that handles thousands of insurance policy transactions every night — the system that runs much of the company's group-benefits administration.

Eight years on, we continue to operate it. Features ship the same week they're written; production stays quiet.

Policies processed nightly ~10k

§ IV · Who we are

A small studio, by design.

Five senior engineers and a small bench. We don't grow by hiring. We grow by deepening the relationships we already have — and we've kept most of them for the better part of a decade.

What we believe
  • Senior engineers, not seats.
  • Discipline, not ceremony.
  • Ownership is collective.
  • Proactive beats reactive.
  • The box stays open.
