About
A small studio for serious software.
Smiling Boy LLC is an independent software studio. We work with startups, scale-ups, and engineering teams that need someone they can trust to ship production code, fix the things that quietly break, and leave the codebase in better shape than they found it.
The name is playful. The work isn't. We bring years of experience across distributed systems, cloud infrastructure, and developer experience — and we keep engagements small enough to care about the details.
- Senior engineers, no handoffs
- Written communication, async-first
- Fixed-scope or retainer engagements
- US-registered LLC, ready to invoice
Services
What we do, end to end.
We pick a small set of engagements at a time so we can stay close to the code and the team we're working with.
Cloud & infrastructure
Pragmatic cloud architecture, CI/CD pipelines, observability, and cost cleanup. We treat infrastructure as a product.
GCP AWS Terraform Kubernetes
Developer experience
Internal tooling, build systems, and platform work that makes your engineers faster without slowing anyone down.
Tooling Monorepos DX
Technical advisory
Fractional CTO and architecture reviews for founders who need a second pair of eyes on the hard decisions.

Why us
Calm, senior software work.
We're a small operation by design. Fewer clients, more attention, better outcomes.
01
Senior, hands-on
You work directly with the engineer doing the work — no account managers, no offshoring layers.
02
Written by default
Decisions, tradeoffs, and progress live in docs and PRs your team can read async, on their schedule.
03
Bias for shipping
We measure success by what's in production, not what's in a status report.
04
Boring infrastructure
We pick tools your team can run on a Tuesday at 3am, not whatever was trending on Hacker News this week.
