Software development

Software development that outlasts the quarter it shipped in.

CogsnGears is a software development company that builds and rescues custom software for businesses that can't afford to guess. From web and mobile applications to internal platforms and integrations, we engineer systems that are durable under real load and legible to the teams who inherit them.

Full-stack development

Web applications, APIs, and platforms built end to end in React, TypeScript, Next.js, Node.js, Python, and Laravel.

Custom software, not templates

We model your domain and build to it, instead of bending your business around off-the-shelf software.

Rescue and rebuild

Inherit a struggling system, stabilize it, then rebuild it into something that scales — our most common engagement.

Shipped and handed off

Tests, docs, and observability as we go, then a clean hand-off so your team can run it without us.

FAQ

Questions, answered.

What does a software development company like CogsnGears actually do?

We design, build, and ship custom software — web applications, platforms, internal tools, APIs, and integrations — and then hand them off to your team documented and observable. We also rescue and rebuild systems that have outgrown their original design.

How much does custom software development cost?

It depends on scope. Projects on our quote form span from under $10k for focused work to $100k+ for full platforms, with timelines from a few weeks to six months. We scope sharply before writing a line of code.

What technologies do you use?

React, TypeScript, Next.js, Node.js, Python, Laravel, PostgreSQL, and the AWS/Kubernetes platform layer — chosen for durability, not novelty.

Can you work with our existing team?

Yes. We embed with in-house teams, lead delivery, or provide senior firepower on a specific problem — then hand off cleanly.
