Omu Systems is a US-based software consulting firm founded by Jacob Parrott, a senior software engineer with over five years of experience building revenue-critical backend systems at scale.

Previously at Engine (formerly Hotel Engine) and FIS, Jacob has architected pricing engines, microservices, and data pipelines that have generated over $30M in measurable revenue impact.

Based in Japan with full US work eligibility, Omu Systems operates on an async-first model with 3–4 hours of daily overlap with US business hours for standups, pair programming, and strategic discussions. Your team gets deep, focused engineering work delivered daily—plus real-time collaboration when it matters.

US WORK ELIGIBLE

American citizen operating a US-registered LLC. No visa complications, no compliance headaches.

ASYNC-FIRST WORKFLOW

Deep, uninterrupted engineering while your team sleeps. Thorough written communication and documentation.

SENIOR-LEVEL ONLY

No junior handoffs. Every line of code, architecture decision, and review comes from senior-level expertise.

What We Build

End-to-end backend engineering for complex business problems. From system design to production observability.

Microservices & System Design

Decompose monoliths into well-bounded services. gRPC contracts, domain modeling, and architecture that scales with your business.

Backend Development

Production-grade APIs and services in TypeScript, Node.js, Python, Golang, and Rust. Built for reliability, tested for confidence.

Pricing & Business Logic

Revenue-critical pricing systems, dynamic margin optimization, and strategy frameworks that drive measurable financial outcomes.

Data Pipelines & ETL

Automated data workflows, event-driven architectures, and streaming pipelines. AWS Glue, SNS/SQS, and custom orchestration.

Observability & Monitoring

DataDog, Sentry, and custom alerting. Correctness frameworks, automated anomaly detection, and dashboards that surface real issues.

Infrastructure & DevOps

Terraform, Docker, Kubernetes, Argo CD, and CI/CD pipelines. Infrastructure as code for repeatable, auditable deployments.

How We Work Together

Omu Systems operates async-first from Japan, giving your team an extended development cycle. Deep engineering work happens during focused hours, with 3–4 hours of real-time overlap daily for collaboration.

01

DEEP WORK

Focused, uninterrupted engineering during Japan daytime. Complex architecture, implementation, code review, and thorough pull request documentation delivered by the time your team logs on.

02

SYNC WINDOW

3–4 hours of daily overlap with US business hours for standups, pair programming, design discussions, and sprint ceremonies. Real-time collaboration when it counts.

03

ASYNC HANDOFF

Detailed written updates, Loom walkthroughs, and comprehensive PR descriptions. Your team picks up exactly where things left off—no context loss, no blocking.
