COLDSEA · SOFTWARE STUDIO

WE BUILD HARD SOFTWARE

We design and build custom software and the systems architecture behind it, then run it in production. ColdSea Deploy, our enterprise Windows deployment automation platform, is what that looks like shipped.

[01]

What we build

A small team of senior engineers. We take on the parts of a system that are hard to get right: real-time data, multi-tenant platforms, hardware in the loop, migrations that can't lose a row.

Custom software development

Production software built end to end: web applications, APIs, internal tooling, and cross-platform desktop clients. Typed, tested, and maintainable from the first commit through deployment. Recent work spans multi-tenant SaaS, real-time dashboards, and desktop apps that drive real hardware.

Systems architecture

The design underneath the software: data models, service boundaries, authentication and multi-tenancy, real-time pipelines, and the deployment topology. We architect systems that hold up in production and scale as you grow, then document the decisions so your team can carry them forward.

Systems integration

Connect isolated systems, legacy databases, vendor APIs, and hardware into one coherent, observable ecosystem.

Data migration

Move legacy data to a new platform with integrity: schema mapping, validation, reconciliation, and a cutover plan that holds.

Data acquisition

Capture and triage data from remote sensors and field devices in real time, from the edge to a queryable store.

Technology consulting

Architecture review, technical due diligence, and a pragmatic path from an idea to a shipped system.

ColdSea Deploy

ColdSea Deploy is our flagship product: an enterprise platform that takes Windows fleets from bare metal to fully configured through visual workflow automation. It is also our proof of work. Multi-tenant, real-time, API-first, and running in production today.

  1. 01

    Configure

    Compose a workflow from reusable, versioned components to configure the OS and install apps, drivers, and updates.

  2. 02

    Provision

    Build an OS installer with your license, edition, deployment drivers, and partition layout.

  3. 03

    Deploy

    Boot the installer to deploy Windows and your workflow, with real-time updates streamed to the dashboard.

Visual workflow engine

Ordered, versioned steps with conditions, dependencies, and per-step telemetry.

Reusable components

User, grouped, and system components with versioning and rollback.

Driver-pack catalog

Vendor sync for Dell, HP, and Lenovo with integrity hashing.

Real-time monitoring

Live execution status and per-step output, streamed as it happens.

Multi-tenant and RBAC

Organization isolation, role-based access, and full audit logging.

Pull-based security

Clients initiate execution, so no inbound firewall rules are required.

How we work

Senior hands only

A small team that writes the code. No layers between the people you talk to and the people building your system.

We operate what we build

Deploy runs in production under our own hand. We design for how software behaves on day two: upgrades, failure modes, and the on-call pager.

Typed, tested, observable

Static types, real test coverage, and instrumentation from the start. Systems you can change with confidence.
