Engineering
Engineering at 11Seas means senior people writing maintainable code, not a large team producing volume. Ninety-five percent of engineers on our projects are mid or senior level, and every line of code is reviewed before it merges.
We build mobile apps, web platforms, and the cloud infrastructure underneath them — with architecture decisions made against your actual growth curve rather than a hypothetical one.

Mobile Engineering
Native and cross-platform applications built for performance and offline resilience.
- Swift and Kotlin for native iOS and Android
- React Native and Flutter for cross-platform
- Offline-first data sync and conflict handling
- App Store and Play Store release management
Web & Backend Engineering
Web platforms and the APIs behind them, built to be extended by whoever comes next.
- React and TypeScript front ends
- Node.js, Python, and Laravel services
- PostgreSQL and Redis data layers
- REST and GraphQL API design
Cloud & DevOps
Infrastructure that deploys predictably and recovers gracefully — CI/CD pipelines, containerization, monitoring, and alerting configured from the start rather than bolted on after an incident.
AI & Data Engineering
Where AI genuinely improves a product, we integrate it deliberately: retrieval pipelines, model integration, evaluation harnesses, and honest cost analysis before committing to an approach.
Two ways to build the same system
Volume-based delivery
- Large team producing code quickly
- Architecture decided by whoever starts first
- Tests written if time allows at the end
- Undocumented decisions live in people's heads
- Scaling problems discovered in production
Senior-led engineering
- Small team of engineers who have shipped before
- Architecture reviewed against your real growth curve
- Automated tests running on every commit
- Setup guides, architecture notes, and runbooks maintained
- Load tested before release, not diagnosed after

Questions
Commonly React, React Native, TypeScript, Node.js, Python, Laravel, Swift, Kotlin, Flutter, PostgreSQL, and AWS or GCP. We pick per project rather than defaulting to one stack.
Yes. We start with a short audit to understand the architecture and current state, then work incrementally. We don't propose a rewrite unless the numbers genuinely justify it.
Peer review on every pull request, automated test suites in CI, linting and type checking, plus periodic architecture reviews as the system grows.
You do — fully. Source lives in your repositories under your accounts, with complete IP transfer written into the contract.
Yes. Unit tests on business logic, integration tests on critical paths, and end-to-end tests on core user journeys. Coverage targets are agreed per project rather than chased for their own sake.
Regularly. We join your standups, use your tooling and conventions, and participate in your code review process as one team rather than a separate vendor.
Why 11Seas
Code that outlives the engagement
The real test of engineering work is what happens six months after handoff. We build systems a different team can understand, extend, and operate — because most of a product's life is maintenance, and that's where sloppy architecture gets expensive.
